Dating

Justin Bieber showed how much of a smooth operator he is by pulling a move on Hailey Baldwin that also signals just how serious they are this time around.

The couple hung out in Brooklyn Sunday where they looked so in love they were completely oblivious to anything going on around them. Besides your standard making out, Justin also hit Hailey with the ol' forehead kiss. Makes 'em melt every time.

Sucking face in public ... it's become their thing.

They've been practically inseparable since rekindling things last month ... although, Justin did take a brief break on Friday when he flew West for a special delivery.

Tom Brady can cross sixth member of the Backstreet Boys off his post-football plans ... 'cause AJ McLean says the Pats QB's singing is way too garbage for that.

We brought you the story last week ... TB12 had a date night with Gisele out at U2's concert in Boston when he screeched out the words to "Vertigo" and "Pride (In The Name of Love)."

When we showed AJ the clips ... his reaction was the same as mostly everyone else's ... "Not everybody is supposed to be a singer."

McLean did give props to Brady for sharing his, um, voice with the world ... saying it took "cajones" for Brady to do that.

Olivia Culpo and Danny Amendola are vacationing in Spain together ... and when we say the views are spectacular, we ain't talkin' the Torre de Savinar.

The on-again, off-again couple are getting some quality time on the Spanish islands this week ... but Olivia ditched the dudes for an all-girl yacht trip with friends.

So, what are they up to? Taking lots of photos of each other in sexy poses ... and for good reason, they're all insanely hot models.

As for Amendola, the two were spotted at dinner together the other night -- not the greatest body language -- but couply enough.

At least his tan looks great!

Remember, the two broke up back in March after dating for 2 years -- but they started hanging out again at a friend's wedding earlier this month ... and now, boom -- European vacation.

Totally back together, right?

Nick Jonas ain't the only one dating up ... add DJ Flume -- one of the hottest EDM artists in the world -- to the list because the 26-year-old is now dating 40-year-old and best-selling author, Kelly Oxford!!

Sources tell TMZ ... Flume and Kelly have been dating for several months. They met at a house party last fall and they've been going strong ever since. The Australian DJ -- with more than 1 mil followers on Instagram -- shows up on her IG as far back as November 2017.

Kelly -- who has 3 children -- was shamed earlier this year after posting pics from a sexy photo shoot. Unclear where the hate's coming from ... she's a smoke show and she's also a badass who can hold it down in her own right. Kelly's written 2 books -- including the New York Times Best Seller "Everything is Perfect When You're a Liar" -- and a couple screenplays.

She's also on powerhouse William Morris Endeavor's speakers circuit roster. Again, total badass.

Get it, Flume.

Justin Bieber and Hailey Baldwin must really have a thing for PDA ... cuz the two were caught sucking face again out in the open.

The newly crowned lovebirds were spotted in an NYC park Thursday in a full embrace and oblivious to everyone walking by. It's unclear just how long the two had been standing there, but they seem pretty comfortable macking in the open.

TMZ broke the story ... Justin and Hailey -- Jailey? ... meh, maybe not -- have been on a PDA parade around NYC over the last week. The couple was first spotted making out in a Brooklyn park near the water, then later sharing some smooches on an NYC park bench.

Donald Trump Jr. clearly has his marriage in the rearview, because he and GF Kimberly Guilfoyle were all about it Thursday night at a Poison concert.

The President's son and the FOX News host hit up the concert at the Jones Beach Theater in Long Island, New York. They were front row and clearly having a good time.

Ben Simmons is pulling a Khloe Kardashian -- getting back together with his significant other after she sucked face with another person!

Just weeks after Kendall Jenner was spotted making out with Anwar Hadid, she seems to be fully back with the 6'10" Simmons ... because the 2 partied in Hollywood on Thursday until 2 in the morning!!

Check out this video of the couple (?) leaving Hyde nightclub on the Sunset Strip right around closing time and driving off in the same SUV.

One thing we also noticed ... 21-year-old Ben gave a stiff-arm to the rose lady who was hoping the NBA star would reach into his pockets to impress Kendall after the club.

Justin Bieber put a ring on it -- on HIS finger, anyway ... but chill, Beliebers. He ain't married yet.

Sources close to the Biebs tell TMZ ... Justin wanted to play a prank on paps by slipping a band on his left ring finger. He figured he'd sit back and watch the internet explode -- and that's pretty much what happened. Fans who posed with him wondered if he'd gotten hitched to Hailey Baldwin.

Seems Kyrie Irving and Chantel Jeffries really are a thing -- 'cause the two were spotted on a movie date together on Monday ... and we're told they looked like a couple.

The NBA star and Justin Bieber's ex-girlfriend took in a flick at the iPic in Westwood, CA -- "Incredibles 2" -- and they held hands on the way out of the place.

By the way, the iPic is a seriously fancy joint -- it's got a full wait staff, bar and kitchen menu and they serve you in your seat while you're watching the movie!

The two were reportedly spotted in New York earlier this month -- but it's unclear if they were together or just hanging out.

Jeffries -- a DJ -- has been linked to a bunch of stars, including The Weeknd and DeSean Jackson. She was also famously in the car when Bieber was arrested for his DUI back in 2014.

Irving dated Kehlani back in the day -- but recently came out and said they're still good friends.

What relationship issues?!

Khloe Kardashian and her baby daddy, Tristan Thompson, looked very much together Monday night -- partying together all over L.A. ... on a parents' night out.

Just days after moving back from Cleveland, Khloe and the Cavs star started their night at Nobu in Malibu together ... before moving over to The Peppermint Club, where they hooked up with Kendall Jenner and Ben Simmons.

Kendall and Ben ducked out after that while the rest of the gang headed over to Poppy -- where they partied until 2 AM.

Anwar Hadid clearly has a type, because he was necking someone who looks so much like his last hookup, Kendall Jenner, it warrants a double take.

Her name's Sonia Ben Ammar and she's also a model. The two cuddled up outside Poppy, which was the place to be Monday night. Kendall's sisters, Khloe and Kourtney, were at the WeHo hot spot too, but no sign of Kendall ... more on that in a second.

Kendall and Anwar hooked up in NYC earlier this month at a fashion after-party. It apparently wasn't anything serious and didn't cause any bad blood between Anwar's sisters, Gigi and Bella.

As for Kendall ... she didn't crash Poppy Monday night, which likely had something to do with Anwar being there. Her and her on-off beau, Ben Simmons, were nearby at The Peppermint Club.

Hard to tell who moves quicker here, but Anwar couldn't keep his hands off his new girl, even though she seemed to have something else on her mind.

Chris Pratt is apparently a hopeless romantic, who really knows how to make a girl laugh -- just ask Katherine Schwarzenegger!!

Chris was spotted on a picnic date Sunday with Arnold and Maria's 28-year-old daughter. The duo's outing went down up in Santa Barbara, and Chris was a total gentleman -- picking up Katherine at her place and driving her up the coast in his truck ... they even stopped to get gas together.

We've seen Chris get flirty before, but this is the first time we've seen him on a full-fledged date since he filed for divorce from Anna Faris back in December.

While Katherine clearly has a Hollywood pedigree, she's not IN the biz. She's an interior designer and lifestyle blogger.

Pete Davidson was technically single when he started dating Ariana Grande ... TECHNICALLY, but "Friends" fans might not agree.

Sources close to the newly engaged couple say Pete and his ex-gf, Cazzie David, were "on a break" in early May -- but not necessarily broken up for good -- when his relationship with Ariana sparked. But they hit if off, and it quickly became clear Pete was serious about moving on with Ariana.

The good news -- it seems all parties involved are happy with the end result. As we reported, Cazzie's not upset or dwelling on her ex's quick rebound. Hey, if it's good enough for Ross and Rachel.

As for Ariana and Pete -- they're still in full PDA mode with Davidson posting a pic wrapped up with his fiancee, captioned ... "u know what you’d dream it be like ? it’s better than that."

Is Rihanna missing out by not dating Joel Embiid? He seems to think so.

The following is a direct quote:

"I don't want to talk about Rihanna but, you know, I feel like every girl in the world should, you know, taste the process and see what the process is like."

Gotta love a man with confidence.

Remember, Embiid tried to shoot his shot at Rihanna back in the day, but it didn't quite work out for the young NBA star.

So, when we saw him out in Bev Hills the other day, we asked him about it -- and he made it clear he's moving on ... to EVERY OTHER WOMAN ON EARTH!

"Every girl in the world is missing out. You know you got to taste the process, you gotta see what the process is like."

John Cena and Nikki Bella's dinner date looked hard to swallow by the looks on their faces, and we're guessing it had nothing to do with the meals they ordered.

The on/off -- but lately, mostly off -- couple went out Tuesday night to the Cowboy Star Restaurant in San Diego, not far from where Nikki lives.

Witnesses tell us their conversation looked intense during the entire meal -- which could be good or bad. As we've told you .. they've been trying to work things out since Bella called off their engagement in April. Cena begged to get her back, but they haven't announced a reconciliation yet.

No denying ... Nikki did NOT look happy at this particular moment. Glass-half-full types will say they're having a tough convo that'll lead to a reunion. Half-empty peeps will say ... it's the last supper.

Ben Simmons not only ruined his chances at a reconciliation with Tinashe ... he also blew it for EVERY OTHER PRO BALLER -- because the singer tells TMZ Sports she's 100% done with athletes.

The "Faded Love" singer was leaving Delilah in West Hollywood after hitting the club on Wednesday night -- and, after all the drama with Ben, we asked her what she's looking for NEXT in a man.

"Not to be an idiot," she told us ... noting that she finds a LOT of idiots in this town.

And when we asked if that meant no more ballers, she responded ... "Oh yeah. That's 100."

For the record, Tinashe recently dropped a ton of new music with big stars like Future, Offset, Ty Dolla $ign and French Montana ... so who needs NBA stars when you've got rappers?
