Lily Gladstone had to be 100 percent camera ready before she could pose for a portrait with Tim Cook ... yes, even the head honcho himself has to acquiesce to an Oscars glam team.

The actress -- who was up for Best Actress last night, but lost to Emma Stone -- stepped out for Apple's Oscars after-party at the Sunset Tower Sunday evening ... and she was hobnobbing with Apple's CEO, even stepping in to take some photos with him.

Before the cameras could fully snap away, though ... her touch-up crew had to constantly come over and adjust things on her -- which left Timbo awkwardly waiting right by her side.

Check out the video, obtained by TMZ ... TC is trying to figure out what to do with himself as Lily's team keeps doing its work ... moving her dress around, fixing her hair, etc. You can tell he's a bit of an afterthought here -- and he's just there to make her look good!

Tim was notably unbothered ... he just smiled and stood to the side of the chaos. Eventually, Tim and Lily were able to pose for a series of pics -- so, mission accomplished.

Understandable that Lily would warrant this type of attention on Oscars night -- she was one of the front-runners during the ceremony ... but even after losing out to Emma, it looks like people still were hyper-focused on her and wanting to chat her up. Tim ... not so much.

A lot of folks feel like LG actually got snubbed out of a statuette ... but we'll leave that be.

Everyone from "Killers of the Flower Moon" left empty-handed, in fact, but hey ... at least they have each other -- not to mention a bunch of handlers who'll jump in at a moment's notice.

Emma Stone didn't seem to like Jimmy Kimmel's quip about her movie "Poor Things" -- and she let it show right afterward ... now, everyone's playing lip-reader as to what she said.

Clips of the Best Picture nominees played throughout the evening -- and when the "Poor Things" montage went up ... JK dropped a zinger about Emma's R-rated nominated movie, saying, "Those were all the parts of 'Poor Things' we're allowed to show on TV."

The audience chuckled a bit -- but when the cameras cut to Emma in the immediate aftermath of Jimmy's joke ... she quickly said something to her husband, Dave McCary.

On its face -- and based on nothing but trying to make out the words -- it appears she said "What a prick" ... that or "Oh my god." The internet seems to think it was the former.

The moment was immediately picked up online ... and people are still trying to decipher what ES actually said in response to JK insinuating that "Poor Things" was all about sex -- which, to be frank, it kinda is. There's more themes beyond that ... but sex is the main driver.

The only one who can clear the air on what was said is Emma herself -- but she's got a shiny new Oscar to celebrate right now, and she probably ain't gonna spill the tea today.

Anyhoo, it wasn't all tension between Emma and Jimmy during the evening -- in fact, he kicked off the ceremony showering her "Poor Things" performance with praise during his opening monologue ... so he had some love for her, and we're sure ES appreciated it.

In addition to Emma's Best Actress trophy ... her movie also won Costume Design, Production Design, and Makeup & Hairstyling. Big night for the "Poor Things" camp -- jabs regardless.

John Cena stripped down to practically nothing to pull off a streaker bit at the Oscars ... but we now know just how much skin he really showed, and what was actually covered up.

The wrestler-turned-actor took to the Dolby Theatre stage in Hollywood, Calif. in nothing but nude-colored modesty wear to make it appear like he was really naked at the annual industry event. In other words, his junk/ass was covered up after all, so he wasn't totally naked.

As you can see from the new photos ... John was totally unfazed by the minimal amount he had to wear -- as he smiled offstage while waiting for his hilarious segment to begin.

He was even snapped shushing a few people behind the scenes while rocking only Birkenstock sandals and an impressive timepiece.

Remember, John is no stranger to performing in little to nothing -- he famously wrestled shirtless while rocking only denim jorts throughout most of his WWE career.

As for how he pulled off his onstage quick change to present the Best Costume Design category ... the video above shows several Oscars production assistants draping John in fabric as the nominee montage played.

And the commitment to the bit has certainly paid off -- JC's appearance has been applauded as one of the night's highlights.

Other notable moments at this year's Oscars include Emma Stone ripping her dress during Ryan Gosling's performance of "I'm Just Ken," Jimmy Kimmel and Donald Trump exchanging words mid-show, and "Twins" costars Arnold Schwarzenegger and Danny DeVito's reuniting onstage.

Ya gotta wonder how John's ex, Nikki Garcia, felt about the bit -- as she was also in attendance working the Oscars red carpet.

The Oscars are over, and the stars all went out with a bang hitting up after-parties around town -- but the biggest hot spot was 100% Vanity Fair's shindig ... where it was a who's-who.

Hollywood's A-list crowd hit up the magazine's annual post-Oscars get-together -- which has become a staple during awards season, and where just about everyone who was in town swung by to have their photos taken and to hobnob with other celebs post-show.

Of course, ya can't blame anyone for wanting to hit up this Oscars bash -- the red carpet and giant lettering is eye-catching, to say the least, and everyone's dressed to the nines.

The pap shots were something to behold, but once people were inside and mingling -- there was a lot to see there as well ... with lots of different stars crossing paths and exchanging smiles. Indeed, Oscar winners themselves were on hand ... as were the runner-ups.

Some of the celebs on hand ... Da'Vine Joy Randolph, Emily Blunt and John Krasinski, Margot Robbie, America Ferrera, Billie Eilish, Jeff Bezos and Lauren Sanchez, Sydney Sweeney, Sofía Vergara, Lenny Kravitz and lots of others.

FWIW, that wasn't the only game in town ... Beyoncé and Jay-Z threw another party at the Chateau Marmont -- and that bash was just as star-studded. In fact, there may have been some double dipping here.

Just a smidge of the stars who showed up for Jay and Bey's party -- the KarJenners, LeBron James, Kelly Rowland, Ciara and Russell Wilson, Chrissy Teigen and John Legend, Emma Stone, Mark Ruffalo, MGK and Megan Fox, Kerry Washington and more.

It was certainly a night to remember ... especially for some movies like "Oppenheimer," "Poor Things," "The Zone of Interest" and a handful of other flicks that truly cleaned up and swept.

"Barbie" left relatively empty-handed ... as did "Killers of the Flower Moon." That's not to say people weren't happy at the actual ceremony, though ... 'cause they absolutely were.

Peep all the photos showing the behind-the-scenes. A night to remember and then some!

Ryan Gosling did his big musical number at the Oscars  -- getting onstage in front of all his peers and belting out the 'Barbie' standout song ... and he did it guns (n' roses) blazing.

The actor just got done performing 'I'm Just Ken' during Sunday's broadcast -- and it was as epic as everyone expected ... with the Ry Guy fully committing to the bit ... and rocking the house with some killer vocals and even better backing musicians, including Slash!

Indeed ... the top hat-rockin' rocker joined Ryan onstage to play some live guitar, and he absolutely shredded as RG belted out the fan fave from the biggest blockbuster last year.

Ryan even came down to the front row -- where he had Margot Robbie and Greta Gerwig help him sing the tune. And yes, he was fully decked out in all-pink wardrobe for the ditty.

For a little while, it was unclear whether Ryan was actually gonna do 'IJK' at the Oscars -- but in the end ... he finally signed on, and his costar Margot just recently reassured everyone he was itching to do it ... despite him kinda playing coy throughout this year's award season.

It was one of the only 'Barbie' highlights of the night thus far -- Billie Eilish just won Best Song, for 'What Was I Made For,' but it's been fairly quiet for the doll crew otherwise.

We'll see if 'Barbie' ends up getting some love for Best Picture ... or if 1 Oscar is it.

Hollywood is emptying the tank ... partying almost nonstop before the Oscars begin, and the celebs are often running into the same faces at every stop on the circuit.

Check out the fame parade that went down at a Bev Hills house party on Saturday -- Jeff Bezos and Lauren Sánchez were there with their pals Kris Jenner and Corey Gamble ... while Andy Cohen, Rumer Willis, Tracee Ellis Ross, Nicky Hilton and Kathy Hilton also filed into the event.

Flip through the galleries, 'cause there were way more partygoers on hand than we can mention.

Later on, some of those same people made costume changes and headed to the Beverly Hills Hotel for Chanel's pre-Oscars event.

Newlyweds Usher and Jennifer Goicoechea rubbed elbows with the likes of Best Supporting Actor nominee Robert De Niro, Lily-Rose Depp and Kristen Stewart, Willem Dafoe, Sánchezos (Lauren & Jeff) again and Best Supporting Actress nominee America Ferrera.

And, after all that ... the party train was far from done.

Next stop ... the famed Chateau Marmont where Willem made another appearance on Saturday night, and other guests included "Foodgod" Jonathan Cheban, Lil Nas X, Alessandra Ambrosio, Billy Zane, Abigail Spencer and Jodie Turner-Smith.

If this all sounds exhausting it's only because it probably is -- it's the show (your face) part of showbiz, and it's a big part of what makes Hollywood go 'round.

Jimmy Kimmel took some light-hearted shots during his opening Oscars monologue -- but the highlight was probably his reflection on the strikes last year ... for a variety of reasons.

The recurring host -- who was back for yet another gig this year -- kicked things off Sunday by actually running a little bit late ... but once he got going, he was ready to make some jabs and crack some jokes ... most of which landed fairly well with the star-studded crowd.

Jimmy mentioned the fact that Margot Robbie and Greta Gerwig were snubbed this year -- chiding the audience who seemed to agree, since a lot of them are voters -- and he even poked fun at Robert Downey Jr. at one point ... referencing his previous drug use.

Jimmy referenced an old dog-themed movie RDJ was in -- and said if he was ever to remake it ... he know the perfect candidate ... highlighting the dog from 'Anatomy of a Fall.'

The guy hopscotched around in his monologue, but eventually landed on the SAG and WGA strikes -- which consumed much of entertainment in 2023 ... and which created a lengthy work stoppage in Hollywood as labor union honchos and studio execs negotiated new deals.

Jimmy sounded sincere in shouting out everyone who remained on picket lines through that difficult period -- but, of course, he eventually gave kudos in a funny, backhanded way.

Check it out ... Jimmy says the strikes taught everyone a good lesson about what they were made of -- namely, a lot of guts ... even though he said no one would ever be able to pick up a shovel. Jimmy also used a lot of colorful descriptors in patting everyone on the back.

You gotta see it to understand what we mean ... it was both graceful, and pretty insulting.

Jimmy ended on a high note, though, when he brought out a bunch of crew members who work behind the scenes ... saying he appreciated their support through the strikes. Looks like everyone else felt the same way -- 'cause all the production people got a standing O.

Miriam Margolyes says people who are still diehard 'Harry Potter' fans as fully functioning adults worry her a bit -- and she's got a clear message for them ... grow the hell up!

The actress -- who played Professor Pomona Sprout on two 'HP' films back when those were still a thing -- did a recent interview with New Zealand's 1 News, where she was plugging a new project of hers ... and she was quite candid on how she feels about this topic.

Check it out ... Miriam says people that are still obsessed with the 'Harry Potter' movies -- or, god forbid, the even older books -- concern her ... 'cause they're still acting like lil' kids.

She says she'll still get asked about 'Harry Potter' stuff to this day -- and goes on to say she's startled to hear people are doing whole ass 'HP'-themed events ... including weddings. Miriam jokes that she wonders what the first night of fun would be for 'HP' newlyweds.

As Miriam puts it, 'Harry Potter' is for children, and the adults still clinging to their childhood nostalgia need to get over it. MM hits the point home by definitively saying ... "It's over!"

Yes, it's a bit harsh -- but you can tell Miriam just doesn't understand the years-long fandom.

The director of 'The Holdovers' is being accused of ripping off another Hollywood creative, who claims the guy hijacked his own years-old script in what he calls outright plagiarism.

Simon Stephenson -- whose story/writing credits include 'Luca,' 'Paddington 2' and other big hits -- levied a heavy plagiarism allegation against Alexander Payne earlier this year with none other than the WGA ... and his claims are just now coming to light publicly.

According to Variety -- which has reviewed and published emails from this whole ordeal -- Stephenson hit up some WGA honchos to complain that Payne's script/story for 'The Holdovers' was a "brazen" ripoff of a script he wrote back in 2013 called 'Frisco.'

Not only are the plots nearly identical, Stephenson alleges, but he goes on to claim there is "line-by-line" replication ... adding he has proof Payne reviewed his screenplay in years past.

Stephenson wrote in one of his emails to WGA, "I’ve been a working writer for 20 years -- in my native U.K. before I came to the U.S. -- and so I’m very aware that people can often have surprisingly similar ideas and sometimes a few elements can be ‘borrowed,’ etc."

He adds emphatically ... "This just isn’t that situation. The two screenplays are forensically identical and riddled with unique smoking guns throughout."

Stephenson was reportedly told his gripes were not a guild issue, and that he might need to consider a lawsuit to address his concerns -- no word on whether he's done that yet.

As for Payne -- who's not a writer on 'Holdovers,' but who says he heavily supervised the script-writing process -- he's publicly said his flick is loosely inspired by a 1935 French film.

As Hollywood's rich and famous trickle in for the Oscars this weekend -- a massive protest is going down just a stone's throw away ... with folks hitting the streets to speak on Palestine.

A huge demonstration is unfolding about a mile away from the Dolby Theater in Hollywood Sunday -- at none other than the Dome Entertainment Centre, in fact -- where hundreds of people gathered with signage, megaphones and Palestinian flags ... while up in arms.

Of course, this is a pro-Palestine protest -- one that's been organized by groups like Writers Against the War on Gaza LA, Film Workers for Palestine, SAG-AFTRA Members for Ceasefire and others ... with their main message being, "No awards during a genocide!"

Another tagline being used for this protest ... "While You're Watching Bombs Are Dropping."

It goes without saying ... these folks are protesting against the ongoing war in the Middle East -- this as Gaza continues to be under siege as Israel seeks to eradicate Hamas.

As you can see ... tensions were high here, as people chanted and made their voices heard ahead of the biggest night in Hollywood. The Oscars are just about an hour from starting.

Unfortunately for these demonstrators, they won't be getting much closer to the actual Oscars venue itself -- the Dolby Theater is blocked off by cops, who've set a wide perimeter ... and who are standing guard with their riot gear ready to go in case things escalate.

Meanwhile ... the stars are getting ready for the big show -- lots of red-carpet arrivals are happening right now ... and they don't seem too worried about the ruckus up the block.

Y'know it's Oscars weekend when even the likes of Nicolas Cage are out on the scene ... in this case to honor "Killers of the Flower Moon" director Martin Scorsese and the cast of his Best Picture-nominated film.

TMZ got video inside the Bev Hills celebration, where Nic, himself an Oscar winner, and his wife Riko Shibata mingled at the Giorgio Armani-hosted party.

It's a rare sighting of Cage at showbiz events. He's more of a karaoke bar kinda guy, but, like we said, it's that kinda weekend in Hollywood.

Several other nominees were front and center ... including 'Flower Moon' star Lily Gladstone, who's up for Best Actress. She's already made history as the first Native American woman nominated for the award, and most critics say she's got a good shot to win Sunday night.

Her costar, and Best Supporting Actor nominee, Robert De Niro was there and looked to be in good spirits ... as he stopped to take a few snaps with folks. We also got shots of last year's Best Supporting Actor winner Ke Huy Quan, Olivia Munn and John Mulaney, Jane Seymour and Paris Jackson doing the small talk thing.

Other faces in the crowd -- Best Actor nominee Jeffrey Wright, Alessandra Ambrosio, Scott Eastwood and Callum Turner, who was not with his relatively new GF Dua Lipa ... unfortunate, for him, and everyone else there.

Jonathan Majors' Hollywood career isn't over yet -- even as his sentencing looms, he's going full gym rat, getting in shape for an upcoming film shoot ... and we got a glimpse of his routine.

Sources close to Majors tell TMZ … he was in L.A. for a week, hitting the gym hard and training for a possible gig before flying back to New York.

No word on what Jonathan's potential role might be, but we're told it would require him to be in incredible shape ... and that's why he was training so intensely.

Our sources say Jonathan's aiming to get shredded -- like superhero ripped -- and the video shows he's getting pretty close to that goal.

Remember, Jonathan was a Marvel star before the studio dropped him immediately after a New York jury found him guilty of misdemeanor assault and harassment for the now-infamous incident with his ex-GF, Grace Jabbari.

We're told Jonathan's working out with his regular trainers, who are getting him in tip-top shape.

For the next month or so, our sources say Jonathan will be shuffling back and forth between visiting Meagan Good in New York and training in Los Angeles.

What's unclear is when the movie shoot would begin -- if he lands it, time is of the essence ... assuming he'd have to get it done before he's sentenced.

The CAA Pre-Oscars shindig was the place to be ... with the best of the biz out to play at The Sunset Tower Hotel, gearing up for the glitz and glam to come on Sunday.

The legendary bash is known as one of the major Oscars warm-up events, and just like every year, Friday night's shindig featured a who's who in Hollywood with lots of the nominees -- like Best Actor hopeful Cillian Murphy -- in the mix and rubbing elbows.

Previous Oscar winners Viola Davis and Brendan Fraser were also part of the line-up -- along with Chris Rock and Sacha Baron Cohen. Of course, it's been 2 years since Chris was targeted by Will Smith onstage at the Oscars -- so, it's nice to see him back enjoying the festivities.

Some of the others mingling the night away were Danny DeVito, Demi Moore, Jeff Goldblum, Donald Glover, Sir Patrick Stewart, Best Actor nominee Jeffrey Wright, Chris Evans, Salma Hayek, Olivia Wilde, and Neil Patrick Harris.

The future of the movie biz was also on hand ... younger actors like "May December" star Charles Melton and Anya Taylor-Joy, "Top Gun: Maverick's Glen Powell and model Kaia Gerber.

Now, they're not big screen stars, but the hosts with the most Andy Cohen and Kelly Ripa kept the party vibes going strong at the bash, which had DJ Rashida and Lady Sha spinning the beats.

CAA reps some of the biggest names in the biz -- such as "Barbie" stars Margot Robbie and Ryan Gosling -- and it hosts this pre-awards bash every year to celebrate clients, colleagues and peers.

Hollywood's elite are warming up for Sunday's Oscars with pre-parties every bit as celeb-packed as the main event will be ... as Usher, John Legend and Leo DiCaprio rallied in one of the town's more iconic mansions!

TMZ got this video inside the William Morris Endeavor talent agency's big bash in Bev Hills Friday night -- it was held at the Beverly Estate, sometimes referred to as the "Godfather" mansion, and it was absolutely swimming with A-Listers.

Check out these faces in the crowd -- Justin Timberlake, Tobey Maguire, Teyana Taylor, Busta Rhymes, Rob Lowe and, of course, the 3 aforementioned superstars ... all rubbing elbows, literally and figuratively.

Even the celebs themselves seemed starstruck at times ... you can see Justin, Usher and Teyana were posing together for a few snaps as they chatted and laughed.

After their little photo sesh, Justin chatted a bit with some of the other guests as Teyana walked around, mingling.

At one point, Teyana bumped into Busta and the two began to shoot the breeze. Rob was also spotted making the rounds.

Never one to miss a party filled with beautiful people ... Leo, along with his pal Tobey, popped in just as the music started pumping and everyone was hitting the dance floor.

By all accounts, Leo was in good spirits and not even hiding his face that much, as we usually see him.

As for John Legend ... Mr. EGOT got off his feet to do the small talk thing ... sitting on a couch to chat up some other guests.

By the way, the mansion where all this was going down is the spot where they filmed the famous horse's head scene for "The Godfather" flick.

A dog featured in a movie that's up for an Oscar this year reportedly ruffled feathers at an awards event last month -- where other contenders got pissed off for him being a good boy.

Back in mid-February ... the border collie from 'Anatomy of a Fall' -- whose real name is Messi but who goes by Snoop in the film -- made an appearance at the Oscars luncheon ... where he was a big hit with all the stars, especially with Ryan Gosling, who seemed pretty smitten with the pooch.

Nothing wrong with bringing the dog from the film to make a little cameo for a pre-Oscars powwow right??? WRONG!!!! At least that's how some felt about it behind the scenes.

According to THR, production companies (and presumably studios) that have films up for Academy Awards apparently complained about Messi's presence at the luncheon ... griping that the dog being there and being so popular was giving his film an unfair advantage.

The dog showed up when Oscar voting was still going on -- and per THR, multiple companies with their hat in the ring complained to Academy honchos about it.

Fast-forward to today -- and the newest news is that Messi will be MIA from Sunday's ceremony ... a bummer, of course. Whether that decision has anything to do with the luncheon "scandal" ... jury's out. THR reports the luncheon thing had always been planned to be a one-off for Messi -- but if his being there angered that many people, who knows!

BTW, this dog is super talented -- and some have joked that it might actually be worthy of an Oscar nod itself. If you haven't seen 'Anatomy' yet ... there's a memorable scene with the dog, where it almost overdoses on aspirin ... and it plays out looking scarily real.

As it turns out ... that's because it was, meaning the dog was actually playing dead. A BTS look at how that came to fruition surfaced this week -- and it's pretty fascinating. Smart pup!

Alec Baldwin may look to enlist the help of other celebs when his manslaughter trial over Halyna Hutchins' death gears up this summer -- but there's a catch ... TMZ has learned.

Sources with knowledge of the case tell TMZ ... the actor's team is considering putting together a list of famous people to potentially testify on Alec's behalf during his trial in July -- but we're told these stars would be people who've already spoken out in Alec's defense.

Specifically, we're told Alec and his team would possibly be eyeing public figures who've weighed into the issue of whether an actor can be held responsible for weapons on set.

Worth noting ... our sources say this potential witness list hasn't come to fruition just yet -- remember, the trial is still months away -- and we're told nothing is set in stone either.

Still ... if this comes to pass, it'd be major news -- especially with the potential names.

So far ... Alec has received public support from a number of stars, all of whom have taken a firm stance -- namely, that it's crazy to go after Alec for something he wasn't tasked with checking in an acting capacity. Some of those names include Debra Messing, Mickey Rourke, DJ Qualls, Frances Fisher (who also starred in "Rust") and others.

Interesting to note ... some of these actors have already committed to being available in court if Alec should come to call on them -- including Mickey ... who tells us he's game to testify.

Mickey tells TMZ ... "Whatever Alec needs I’ll be there 100%. The armorer is 100% responsible for any gun handed to an actor. Especially, to an actor who didn't have experience with guns."

Rourke adds ... nobody from Alec's legal team has reached out to him yet.

As we reported ... Alec pled not guilty to an involuntary manslaughter charge in January ... over two years after he held the prop gun that went off and killed Halyna during a "Rust" rehearsal. Director Joel Souza was also injured at the time.

The armorer on set, Hannah Gutierrez-Reed, was just convicted of involuntary manslaughter herself -- and while some feel that doesn't bode well for AB ... others disagree, arguing it only cements that the person responsible for weapons on set was found criminally liable.
