Bella Thorne is hanging out with a brand new pro athlete ... and believe it or not, we ain't just talking about her boobs and butt cheeks.

The ex-Disney star was rocking a barely there see-through half shirt and some very tight white shorts during a trip to Six Flags Magic Mountain on Thursday with L.A. Lakers star Jordan Clarkson.

Unclear if they're anything more than friends ... but the two pulled up to the park together in his Lambo.

We know Bella likes NBA players -- she spent a lot of time hanging out with Chandler Parsons earlier this year ... and even kissed him in Mexico.

Scott Disick feels betrayed by Kourtney Kardashian whom he claims held out hope they could get back together at the same time she was banging a 23-year-old model.

Our Scott sources say he's devastated by the pics that came out this week of his 37-year-old baby mama with Younes Bendjima, whom she's been with since October.

From Scott's point of view, Kourtney has dangled a carrot in front of Scott, that she'd be open to getting back together if he got sober and "show respect." He says he hasn't hit the bottle in months and believes he's been extremely good to her.

So, you ask, how can Scott seriously think she'd get back with him if he's been with at least 3 women over the last 6 months? The way Scott sees it ... it was "retaliation" after Kourtney hooked up with other guys.

He also thinks it's been super unfair that when he missteps, the entire Kardashian family comes down on him like a ton of bricks, but when she crosses the line, everyone in her fam gives her a pass.

All that said, Scott wants back with Kourtney, but she's got other things on her mind and various other body parts.

Barack Obama seriously dated several women before meeting Michelle, and none of them were African-American, according to the author of one of the definitive books about the former president.

Christopher Andersen, who wrote "Barack and Michelle: Portrait of an American Marriage," appeared on "TMZ Live" just after excerpts from another book -- "Rising Star: The Making of Barack Obama" -- were released, saying he twice proposed to a woman before meeting Michelle.

Andersen says Obama, who had big political aspirations early on, recognized the value of marrying a black woman, although he's quick to add the love between Barack and Michelle is real and profound.

12:20 PM PT -- A rep for Hailee says she and Justin are friends. That's her side of it.

Our sources are clear ... their relationship has left the friend zone.

Justin Bieber's moved on to a new Hailey -- different spelling though because he's now dating singer and actress Hailee Steinfeld ... TMZ has learned.

It's all still fresh. Our sources tell us they've only been seeing each other for a little over a month -- though that's a lot in Bieber's world. We're told they were introduced by pastor Carl Lentz. They both attend his church.

Last month, JB dropped a giant clue things were heating up between them when he was photographed mid-FaceTime with the "Pitch Perfect 2" star.

Justin's in NYC now and we're told they met up after Hailee went to the Met Gala ... solo.

Kendall Jenner was happy to leave half of her skirt behind for a Met Gala after-party in NYC ... and she seemed content to leave A$AP Rocky back there as well.

Kendall and A$AP hit up 1 OAK after the Met Gala Monday night, where she was looking pretty damn hot in almost half of a leather mini skirt barely held together by strings.

Travis Scott's birthday dinner was quite the event ... for his new gf, Kylie Jenner, who showed up in force with her whole crew for the festivities.

Kylie, her big sis Kendall, Bella Hadid, Hailey Baldwin and Cara Delevingne all rolled into Cipriani Sunday night to celebrate Travis' 25th.

Kylie and Travis have been pretty inseparable since Coachella ... and, based on the showing at this party ... her pals are giving them the stamp of approval. Afterward, they all headed to Travis' show at Terminal 5 where things got a little raucous.

Lit birthday, for sure.

Travis Scott might have been rocking a sweater ahead of his show Saturday night ... but that doesn't mean Kylie Jenner wasn't giving him goosebumps underneath.

Kylie was seen tagging along with Travis at his gig at Bentley University just outside of Boston, where she was clinging to her new man at the hip.

We're told the couple went to a Boston club called Bijou afterward, and were together a majority of the time except for when Travis was on stage performing.

He didn't mention her during the set ... but this picture's worth a thousand words. So is this one.

Joe Jonas and Sophie Turner are working out as a couple ... literally.

Paps spotted the pair holding hands as they left a gym sesh together Saturday in the East Village in NYC. As you can see by their workout gear ... things are getting physical between them.

We already know Joe's super athletic -- he boxes and whatnot in his spare time. Looks like he's getting Sophie into that ultra fit life too.

Plus, she's already made it clear Joe's giving her that good good. So again ... get it, Sophie!

Aaron Rodgers was spotted at an L.A. golf course Thursday with a very attractive blonde -- and we're told it's "Baywatch" actress Kelly Rohrbach.

Just a few weeks after reports surfaced he split with longtime girlfriend Olivia Munn -- the Green Bay Packers quarterback hit up the Westchester Golf Course.

Witnesses tell us Rodgers and Rohrbach appeared to be holding hands and looked flirty -- until they noticed people watching them.

Both Rodgers and Rohrbach are avid golfers -- so maybe it was just a platonic trip to the links.

Then again, maybe not.

Kylie Jenner and Travis Scott jumped from holding hands at Coachella to holding way more at an NBA playoff game, and yet ... they're still in the heavy flirting with a chance of banging stage.

The rapper was courtside in Houston Tuesday night for the Rockets-Thunder game and must've thought rubbing Kylie's inner thigh would bring his hometown Rockets good luck.

This comes on the heels of Coachella ... where sources at the music fest tell us Kylie showed up to support Travis as he headlined the second biggest stage. KJ was there with her own pals, but the social media clip of them holding hands doesn't lie.

We're told they were super flirty in the desert, and although nothing was consummated ... all signs point to it happening soon. Our sources add ... they've been close for years, since they both appeared in a Justine Skye music video.

From the looks of it, they moved a BIG step closer to banging in Houston.

Timing might not be great -- he's touring with Kendrick Lamar this summer, and she's fresh off the breakup with Tyga breakup.

But as they say, the best way to get over a rapper is to find another one ... who can pay his bills.

Jesse Williams has been separated from the wife he is now divorcing for more than a year, and he's been hanging out recently with Minka Kelly.

TMZ broke the story ... Jesse filed to end his 5-year marriage to Aryn Drake-Lee ... they've actually been together for 13 years. They have 2 children, the youngest is a year old.

As for Minka, they're shooting a video game/movie in Paris and have been seen both on and off set for the last few months, but no one's saying if it's anything more than a friendship.

A lot of Jesse's fans are upset he's moving on, but a source connected with the couple tells TMZ ... as far as Jesse's concerned, the relationship has "played itself out."

Yes, J Lo ... A-Rod is just that into you, and the poor guy couldn't even hide it Monday afternoon as the two grabbed lunch in New York City.

The couple had a fancy meal at The Sea Grill, which is just above the Rockefeller Center ice rink. Plenty of city sights to see outside, but Alex was transfixed by his date.

Be honest ... ya kind of want someone to look at you the way he's looking at Jennifer.

OkCupid is fraudulently peddling a dating site with a bunch of "dead" profiles ... so says one of its members who filed a class action lawsuit.

Chad Perkins says he got suckered into paying for a premium service that would allow him to view others who "liked" his profile ... but instead, noticed most, if not all, accounts that liked him were inactive.

In docs, obtained by TMZ, Chad says he paid $44.99 for the "A-List" package, but less than 2 weeks later he noticed no real person actually "liked" his profile. Chad complained but says all he got was an apology for a "software programming error or bug."

Chad ain't buying it, and in the suit he says the website is just covering up its scam. He's suing to get his money back and other damages.

If Tyga's new mystery girl looks familiar, it's not just because she's a Kylie look-alike -- she also used to date Justin Bieber.

Jordan Ozuna was banging the Biebs back in 2014 ... back when she was a Hooters waitress in Vegas. She also worked as a bottle girl there at a famous hotel and casino before moving to L.A. -- where she's apparently hooked up with Tyga.

We're told Jordan and the rapper have been talking and hanging out a lot for a few weeks ... but she's telling people they're just friends.

Wonder if she said the same thing about the Biebs?

David Spade and Naya Rivera ain't a one-off -- they were hanging again, this time on land, and everything about her outfit says he'll be back for more.

The couple did dinner at Nobu in Malibu Thursday night. It's the first time we've seen them together since the shots of them snuggling in a pool a few weeks ago in Hawaii.

Since then David's tried to blow off the relationship, telling us it's NBD. However, Naya's dress at dinner -- cut wayyy up to there -- screams it is. Or at least it was that night.

Plus, let's not forget David's ex Heather Locklear's confirmation ... of the BIG deal.

John Salley knows exactly what Carmelo Anthony should do amidst all his basketball and woman drama -- head west and play for the Lakers!!

The 4-time NBA champ says Melo's not the type to seek advice about his split with La La, but he's optimistic things will get better for the superstar on and off the court ... and thinks L.A. is the place to start fresh.
