Diana Ross pulled out all the stops in the name of Oscar Sunday ... giving people in attendance at Byron Allen's annual gala a night of endless love.

The former Supremes singer was havin' a blast headlining Byron's shindig at the Beverly Wilshire Hotel, busting out some of her classics from the past 6 decades.

The 78-year-old icon performed for about an hour and had 3 costume changes over that period. Yes, Miss Ross still knows how to put on a show!

Believe it or not, Diana wasn't the only big event at this shindig -- attendees could also pay money, which went to Children's Hospital L.A., to get roasted by the famed roastmaster Jeff Ross -- and Chrissy Teigen's mom Vilailuck was one of the lucky donors.

Take a look, Jeff doesn't go easy on her, but we guess that's the best bang for your buck -- no pun intended. Howie Mandel MC'd the roast and threw in his 2 cents too.

Despite Jeff's harsh roasting of several folks who donated to the cause, not a single comedian was slapped!!!

Two L.A. restaurants connected to Tom Sandoval have seen brutal reviews in the wake of his scandal ... it's gotten so bad, Yelp's put the kibosh on the whole thing.

The negative comments target TomTom and Schwartz & Sandy's -- both co-owned by Tom Schwartz and Sandoval -- with all the gnarly reviews coming after Tom's affair with 'VPR' costar Raquel Leviss went public.

One reviewer shared a pic of a Raquel-inspired cockroach they claim they "found" while dining -- dragging Raquel's looks and Tom's band, which the reviewer says sounds like "Freddy Krueger scratching on a chalkboard."

Critics also talk about patronizing a different eatery -- Something About Her -- AKA Ariana Madix's sandwich shop.

And there's this ... "TomTom's a place for pigs and homewreckers."

It didn't get much better over at Schwartz & Sandy's ... with some again calling out the "cheaters" and saying Tom should live in a cave.

Yelp had to pull the plug on reviews for both restaurants ... telling users there's been an influx of reviews because of public attention, so the site hit the pause button while staffers determine if these are real customer experiences.

Avril Lavigne and Tyga aren't gallivanting around Paris to grab headlines ... they're actually interested in dating and getting to know each other without pressure or expectations.

Sources close to the couple tell TMZ … Avril and Tyga are still in the early stages of figuring one another out, but they're not putting any labels -- ala girlfriend/boyfriend -- on anything just yet.

There's been speculation the two are only hanging out as a publicity stunt in order to generate some buzz around a possible music collab. Our sources say that's not true, and the two don't have any music in the works -- they're just really enjoying hanging out.

It's easy to tell they're more than enjoying each other's company -- packing on the PDA during a recent trip to Paris, including a make out sesh at a fashion week party and strolling hand-in-hand through the streets.

TMZ broke the story, Avril called off her engagement to Mod Sun only a few weeks ago, after our Avril sources told us the whole thing had been unraveling for a few months.

Mod Sun was surprised by the news, but has powered through his concert tour to promote his "God Save The Teen" album ... a project with several songs dedicated to Lavigne herself.

D.L. Hughley is pushing back against folks who say Chris Rock deserved to be slapped by Will Smith for making fun of Jada Pinkett Smith ... he finds the narrative extremely ironic.

The comedian ripped into The Root's Candace McDuffie, who went on CNN and claimed Chris had it coming after years of targeting Black women with his jokes, saying she's got it all twisted.

D.L. says Chris isn't punching down on marginalized women, as Candace believes, but rather making fun of celebs who put their business out in the streets ... he says it's all fair game.

The irony for D.L. ... Candace thinking the violent slap was justified while a comedic response goes too far, and everyone's allowed an opinion except for the man who actually got smacked in the face on live TV.

Tom Schwartz hasn't shown too much concern about the outrage over Tom Sandoval's affair with Raquel Leviss -- which makes this performance of Green Day all the more worrisome.

Witnesses tell TMZ ... Schwartz was with pals at The Oaks Tavern in Sherman Oaks for some karaoke -- showin' the crowd his version of Green Day's hit, "Brain Stew."

We're told he picked up his group's tab Wednesday night. It's unclear how long Schwartz and the gang stayed out, but we're told Sandoval definitely wasn't in attendance.

It appears Schwartz isn't all that fazed by what's going on with his best bud right now ... but he should be if ya ask former "Vanderpump Rules" cast member Kristen Doute.

As we reported, Kristen -- who dated Sandoval years ago -- completely dragged Schwartz calling him a "f****** p****" for keeping quiet about his friend's affair. She claims he's expressed concern in texts, but she thinks public actions speak louder.

BTW, Schwartz and Raquel were briefly an item too, having made out during the show's current season ... so, there's a little more drama.

Schwartz has been mum on the cheating affair -- up until Saturday, that is ... when he sat on the fence about who to show his allegiance for ... ultimately tossing up his hands and chalking it up to a major bummer.

GloRilla and Finesse2tymes appear destined for a legal battle over that tragic stampede at their New York concert -- the family of one of the three people who died says they're lawyering up.

Brandy Miller was trampled to death in the chaos that followed the rappers' ill-fated Rochester show earlier this month ... and her sister, Michelle, tells us the family plans to sue Glo and Finesse2tymes, plus the promoters and Main Street Armory.

Michelle says her fam is in the process of retaining an attorney -- they've spoken to several since Brandy was pronounced dead on Monday, and aim to retain someone who's high profile  ... because the family "has no plans to back down."

Finesse and GloRilla had reportedly left the venue before the stampede. They've both expressed how devastated they are about the tragedy, and it doesn't appear either artist is under criminal investigation for the incident at this time.

When TMZ Hip Hop got Finesse in NYC this week, he scoffed at the idea he might be blamed, and flat-out told us he wasn't worried about potential lawsuits.

Ryan Garcia tells TMZ Sports Jake Paul would probably get "beat up" by Floyd Mayweather if the two ever got in the ring ... but he did put at least some respect on the YouTuber-turned-boxer's game -- saying he believes the tilt would at least go the distance.

A potential Paul vs. Mayweather fight appears to be in the works ... after the guys got into a heated back-and-forth outside of the Miami Heat game on Wednesday night.

So, when we got Garcia out promoting his upcoming match with Gervonta Davis out in LA this week -- we had to ask ... who'd win if the fight went down?

Garcia made it clear that despite his friendship with Jake, his money is on Floyd ... "but, guess what," he said, "Jake won't get knocked out."

His explanation for why was simple ... Mayweather couldn't KO Jake's big bro, Logan, in their exhibition match back in June 2021 -- and he obviously believes Jake's a better fighter.

As for the meetup in the streets this week ... Garcia called out Floyd for it all, saying it wasn't "right" to confront Paul with a huge entourage.

But, Garcia told us he isn't too worried about that matchup ... saying his focus is solely on Davis -- who he'll take on next month after years of smack talk.

Kane -- AKA Mayor Glenn Jacobs -- tells TMZ Sports he's focused on running his county right now ... but the WWE legend didn't rule out the possibility of holding other political offices in the future, saying he'd entertain the idea when the time is right.

We recently talked to Jacobs -- currently in his second term as the mayor of Knox County, TN -- and asked the WWE Hall of Famer whether he has ambitions of ascending the political ladder, and running for higher office like U.S. senator or governor.

"I don't know," Glenn said. "I'm just trying to do the best job I can as mayor right now. We'll leave that until the time comes."

Jacobs -- who's been a WWE Superstar since 1995 -- told us he's content in his current role, and wants people to remember him for the difference he's made in their lives through his policies and advocacy.

"What I want is pretty simple," Jacobs said. "People to understand that I cared about my community and wanted to do what I could to make it a better place. As mayor, you don't do that yourself, but what you can do is kind of lay out a vision and get people to the table and somewhat lead the way."

Glenn was inducted into the WWE Hall of Fame in 2021, and says he didn't enter politics for personal gain, but rather to make Knox County "even better than it already is."

Five-star hoops prospect Kiyomi McMiller -- arguably the top girls H.S. basketball player in the country -- tells TMZ Sports she's hoping to get a signature shoe just like Michael Jordan ... after she inked a deal with His Airness' brand last month.

We spoke to the 16-year-old -- a superstar point guard for Life Center Academy in Burlington, NJ -- just a few weeks after she put the pen to paper with Jordan ... and she told us the historic deal is "pretty crazy."

And, she said that now that she's a part of the MJ roster ... she wants her own line of kicks one day -- perhaps with something that ties into her "The Product" nickname.

She added, though, that her "ultimate goal is to be the greatest of all-time."

Kiyomi's parents coached at a local college when she was young, sparking her love for the game -- and it was actually her father, Mike, who came up with her famous moniker. McMiller said Dad thought of it because he believes she can deliver anything that's needed on the basketball court.

McMiller -- who wears #23 just like Mike -- told us Julius Erving, Kevin Durant, Kyrie Irving, Stephen Curry and MJ are her top-five favorite players of all time ... and said the reason she considers Jordan the greatest ever is because he stood out among other NBA greats.

Kiyomi, a junior who's yet to commit to a college, is planning on majoring in communications, sports management or marketing.

We asked McMiller -- whose lethal handles and shiftiness on the court make her a must-see -- what player inspires her game the most ... and she said Kyrie and KD influence how she plays.

Maitland Ward says the adult film industry's awards show is far superior TV than anything the Academy Awards is offering ... and she thinks it boils down to who's doing the voting.

We got the former "Boy Meets World" actress-turned-porn star in Bev Hills and asked why she thinks traditional awards shows like the Oscars are losing interest and viewers.

Maitland says the folks voting for the Oscars are way too old and aren't in touch with the country ... and she thinks the nominations this year once again show a lack of diversity.

On the flip side, Maitland says porn is rife with female directors and performers from all walks of life ... and she thinks the AVN Awards does a better job reading the room and going with the most deserving candidates, with no politics involved.

While awards shows are mostly losing viewers year after year, Maitland has an idea for how the Academy Awards could get a shot in the arm and a ton more eyeballs with a new category ... yep, she wants to see someone win an Oscar for having sex on camera!!!

Maitland has won seven AVN awards since joining the porn industry in 2019, including Best Leading Actress this year.

"I don't think fans wanna tune in to see me wrestle. They damn sure don't tune in to see me do Brazilian jiu-jitsu. So, why not cut the fat and get right to the meat and potatoes."

That's former UFC and Bellator champion Eddie Alvarez, 39 -- one of the greatest lightweight mixed martial artists in history -- on why he's decided to leave MMA for bare knuckle boxing.

Alvarez recently inked a deal with BKFC ... and will fight 37-year-old fellow former UFC star Chad Mendes on April 29.

The men have over 60 pro MMA fights combined (Eddie has 40), but Alvarez points out the sports are considerably different, including the fact that cuts are very prevalent.

"There's a lot of little subtleties that I learned when I went to the event myself. Usually you get cut about a minute or two into the fight, typically there's a cut that goes on and you have to learn and you gotta learn to fight with that," Eddie says.

And, cuts are a serious factor, according to Alvarez, who says seeing one's own blood can screw with a fighter's head.

"Some guys could be world champs, undefeated. Never seen their own blood and when they do, you get to see the bitch in them real quick. You need to see your own blood a few times," Eddie tells us, adding, "I'm very familiar with my own blood. I know what it tastes like, smells like, and oftentimes I don't feel like I'm in a fight until I'm cut."

The Underground King says there are more differences between the sport.

"There's even smaller margin for error. And it's a sprint, not a marathon. You need to be ready when that bell rings. There's no feeling out process."

Eddie and Chad aren't the only combat sports stars on the card. Former UFC champ Luke Rockhold is also boxing former UFC star "Platinum" Mike Perry the same night, and we spoke to the 38-year-old fighter.

"It's different, it's intriguing, and it's f****** scary. F****** crazy shit. I'm a f****** crazy man."

Aside from being a great fighter, Rockhold's also a model (he was previously the face of a Polo Ralph Lauren advertising campaign), so we asked him he if was concerned about his moneymaker getting damaged (see Eddie's comments above about the cuts).

"Do I seem like I'm worried about my face?" Luke joked, adding ... "Mike Perry should be worried about his face cause I plan on putting it right on his f****** nose!"

"I wanna make that nose a little more crooked."

"The Challenge" star C.T. Tamburello and his estranged wife have agreed on who gets the house in the midst of their divorce ... and he won't be the one movin' out.

According to legal docs, obtained by TMZ, Lilianet "Lili" Solares filed back in December to get sole possession of their Florida pad -- but she has now agreed to move out and leave the marital home to C.T.

Docs say Lili will move into a rental property ASAP ... but C.T. will be responsible for the $7,200 deposit for her new place. Lili's only allowed to enter the marital home to get her stuff -- including furniture and personal items, as well as some of their kid's things.

C.T.'s required to pay $761 a month for temporary child support ... and they agreed to stick to a schedule when it comes to taking care of their little one, Christopher Jr.

TMZ broke the story, C.T. filed for divorce last November, putting an end to their tumultuous marriage. No word on what led to the decision, but their relationship issues were front and center on "The Challenge: Double Agents" -- where he revealed they separated back in 2020, before eventually getting back together.

Edwin Castro, the recent winner of the $2.04 billion Powerball prize, grew up in Los Angeles and was once a prominent Boy Scout and high school athlete ... TMZ has learned.

Our sources tell us 30-year-old Edwin rose all the way to Eagle Scout during his time in the scouts, and he attended Crescenta Valley High School in La Crescenta, CA ... not far from Joe's Service Center in Altadena, where he purchased the winning lottery ticket.

In addition to being a Boy Scout, we're told Edwin played football and baseball in high school ... our sources say he grew up in a "wholesome family" that frequently took fishing trips.

Our sources say Edwin, who studied architecture at Woodbury University in Burbank, is a quiet guy with a kind heart.

Since striking it rich, Edwin's already used some of his new money to buy a swanky $25.5 million pad in the Hollywood Hills ... one month after claiming his lump sum payment of $997,600,000 before taxes.

Edwin's new crib has all the bells and whistles, including a home gym, garage parking for seven cars and a motor court ... and we're told he has a passion for classic cars and fitness.

As we reported, Edwin was being sued by a man who claimed the winning lotto ticket was actually stolen, claiming Edwin was involved in the alleged theft ... but the lottery says they have the utmost confidence Edwin's the rightful winner.

One source told us, "Winning the lotto couldn't have happened to a better guy."

The Instagram model who's been down one breast -- thanks to one of her massive implants bursting -- is now sporting a new look that takes a major load off her back.

The Canadian model, who goes by Mary Magdalene on social media, tells us she underwent breast reduction surgery ... going from 5,000cc implants to a mere 700cc. If that sounds like a giant difference, it is -- without her famous pair she's a full 20 lbs. lighter!

Remember ... one of Mary's implants popped last month, leaving her with one 11-pound breast she referred to as her "uni-boob" and a bunch of saggy, tattooed skin where the other implant used to reside.

Mary says she's now a C cup after going under the knife ... a major difference from when she was walking around with K cups. It doesn't sound like those enormous implants did the body any good; she says her actual boobs were so damaged, she had no tissue left.

In addition to a breast reduction, Mary says plastic surgeons also performed a lift, implant exchange and liposuction.

The healing process was brutal ... she says she got an infection and a fever and needed antibiotics through an IV. However, she's feeling better now.

One more tidbit, shall we say ... Mary says she also had a vagina reduction, so she's no longer claiming to have the "world's fattest vagina." Someone call Guinness.

MMA fans are clamoring for a Jon Jones vs. Francis Ngannou megafight ... but Dana White says there's nothing to see there, 'cause the new heavyweight champ would've demolished "The Predator" much like he did Ciryl Gane last weekend!

The UFC president joined Babcock on the TMZ Sports TV show (airs weeknights on FS1) ... when White was asked if he could foresee any situation where he'd welcome Ngannou back to the UFC and make the Francis-Jon fight.

"I'm not interested," Dana said.

"I tried to make that fight for two years. He didn't want the fight. Know what I mean? He didn't want the fight, and he left here without even having another deal in place. And, I know how the boxing world is, it's crazy, but Francis didn't want to [fight Jones]."

Don't be too disappointed ... White says Francis almost certainly would've been easy work for the G.O.A.T.

"Let me tell you what, I think, a lot of other people feel this way, I think that's exactly the way the fight would've gone if [Ngannou] was in there, too."

Of course, Jon made Ciryl look like light work at UFC 285 ... taking him down and forcing a tap out in a shade over 2 minutes.

Dana, using some MMA math, explained why Ngannou wouldn't have stood much of a chance.

"[Francis] and Ciryl had a five-round war, and if Ciryl doesn't go for that submission, Ciryl probably wins that fight. At the end of the 5th round there."

FYI, Ngannou won their UFC 270 scrap in January 2022 by unanimous decision, but it was a very close fight.

Dana then answered the original question -- can you see yourself making JJ vs. FN?

"No."

We also talked to White about the next big heavyweight matchup, Stipe Miocic vs. Jones. There's talk the fight will go down at UFC 290 on July 8 during International Fight Week, but Dana says nothing's set in stone, and there's not much time to get a deal done.

Dana also said he wouldn't be surprised if this is 35-year-old Jones' last fight.

"I wouldn't be shocked either if he fights Stipe and then retires."

We also talked to Dana about his upcoming Power Slap 1 event, going down Saturday night in Las Vegas. The card features four title fights ... including the two top-ranked heavyweights in the world.

White says he sees parallels between Power Slap/slap fighting and the UFC in its early days, when MMA was viewed as being brutal and too violent.

Dana also broke some news about the future of "Power Slap: Road To The Title," announcing they've signed a two-year deal. White says the next season will take place in Dubai.

Travis Kelce is a total natural with a future in acting if he wants it ... so says comedian Jeff Dye, who tells TMZ Sports he was blown away by the Kanas City Chiefs superstar's performance on "Saturday Night Live."

TK made his big debut at Studio 8H last weekend ... and many were impressed with how comfortable he looked on stage as he delivered his lines.

Dye admits he gave a bit of an eye roll when Kelce was announced as the show's host -- because in his opinion, athletes usually aren't funny -- but the tight end turned him into a believer.

"He reminded me of Phil Hartman, that's how good I'd say he was," Dye says. "Not being sarcastic, it was very Phil Hartman-esque."

It goes without saying it's a massive compliment from Dye -- Hartman is a comedy legend ... and spent eight seasons on the sketch show from 1986-94.

We also talked to Dye about who else from the sports world could make the transition over to acting ... and there's one two-time Super Bowl champ he thinks would thrive in entertainment.
