Dating

Something's definitely going on between Zayn Malik and Gigi Hadid ... they partied together Tuesday night and security did their level best to shield them from photogs.

They showed up at The Nice Guy in WeHo at around 10:30 PM where they entered from the back so there's only a fleeting glimpse. Two hours later they resurfaced and left together.

Gigi hit up the same spot Sunday night at Justin Bieber's after-party, where she was photographed leaving in a SUV with Zayn.

Anyone confused?

Smells like a reconciliation for Michael Sam ... 'cause the football player was out in L.A. with his ex-fiance this week ... and TMZ Sports has the video!

We didn't even realize it at first ... but upon further inspection you can totally see Vito Cammisano leave Craig's restaurant with Sam and get into his waiting SUV on the way to the nearby Nice Guy bar.

Sam and Vito were hanging with male model Shaun Ross that night ... and later in the evening, Ross and Vito posed for a pic together.

Sam and Vito split back in June -- just 6 months after the two got engaged during a romantic couples trip to Italy.

The two came together to shoot an anti-bullying video last month ... and it may have been the beginning of a reconciliation.

No word how serious they are -- considering they went out with a 3rd wheel -- but it seems like they're headed in the right direction.

Kylie Jenner goes from breakup to "until death do us part" faster than anyone ... because she and Tyga are going to get married, and that's straight from her mouth.

The recently reunited couple was out after the American Music Awards Sunday night when someone popped the question.

She did not hesitate with her answer ... if only we could see Tyga's face.

Ah, young love.

Kylie Jenner was flying solo Friday night -- no Tyga in sight -- but she may not have left solo.

The freshly-single 18-year-old partied at Hyde on the Sunset Strip in WeHo until 2 AM. Apparently Justin Bieber was inside and so was A$AP Rocky.

You can see from our video, Kylie and A$AP leave in the same SUV.

Teenagers heal more quickly.

Justin stuck to his theme of giving impromptu performances by jumping on a table inside the club to perform "What do you mean?".

Khloe Kardashian was rushing to divorce Lamar Odom, so she could be with James Harden -- and only pulled the divorce papers because Lamar was in a coma.

Khloe went on Ryan Seacrest's KIIS-FM radio show to talk about Lamar's health, and her relationship with NBA superstar, Harden -- and she makes it seem like they never broke up throughout Odom's near-death experience.

TMZ broke the story ... when Khloe and Lamar called off their divorce, she hoped they would reconcile. But Monday morning, it sounded like Harden's been waiting in the wings all along. She told Ryan, "There are times I’m sure he was very uncomfortable with things. But I’m glad he’s been so supportive to me."

Giada De Laurentiis moves fast ... and she's got fast moves.

The cooking star and her new BF Shane Farley were all over each other in Houston Saturday night at La Grange bar.

Giada -- whose divorce became final in September -- was all over Shane, and he was more than a willing participant.

Giada was in town for a book signing earlier in the day ... lipstick in tack.

Who would've guessed Katt Williams would turn out to be the world's greatest boyfriend ... in addition to showering his gf, Hazel-E, with extravagant gifts, Katt's also cool with other men rubbing their junk all over his gal.

Hazel-E hit the popular Sin City striptease Thunder From Down Under over the weekend and from the looks of the video, really weathered the storm.

Khloe Kardashian and James Harden made their first public appearance together since Lamar Odom's medical emergency.

Khloe and James arrived together at Lure nightclub in Hollywood around midnight Sunday and stayed for 2 hours. They left separately.

Gwen Stefani was attracted to Blake Shelton like a magnet, because he resurrected her self-esteem ... so say some of her closest friends and associates.

Gwen told people in her life, Gavin Rossdale was a "control freak" who said disparaging things to keep the upper hand in the relationship. Our sources say Gwen complained Gavin had an issue with her parenting skills and criticized her for not being a supportive wife.

Gwen, we're told, was "blown away" by the kindness Blake showed her after she split with Gavin. "It made her feel good again," said one source. Blake also won her over by just being fun ... something Gwen said she had been missing in her life for a long time.

For his part, we're told Blake called Christina Aguilera last week -- before he hooked up with Gwen -- and told Christina he had "a crush" on Stefani. Christina's response offered little hope ... "Ha, good luck with that." Turns out Christina underestimated him.

You gotta love the honesty from Eric Dickerson ... who says if he was a young, star athlete today -- there's no way he'd date just one woman ... he'd try to sample ALL of the Kardashians!!!

This clip is awesome ... the NFL Hall of Famer tells TMZ Sports, athletes should go out and have a good time and enjoy ALL of the perks of being a celebrity ... as long as they do their job.

But when we specifically asked about Kim, Khloe, Kendall and the rest of the K-squad, Dickerson's answer was the best.

"Let me put it to you like this here ... if I was in my 20's, I'd be dating them all."

Blake Shelton and Gwen Stefani are dating ... TMZ has confirmed.

A rep for Gwen tells TMZ they wanted to reveal the new relationship Wednesday night as they celebrate the CMAs in Nashville.

We're told Gwen and Blake will be attending several after-parties following the awards ceremony.

Our sources say Gwen made the decision at the last minute to fly to Nashville with Blake. We're told her plan is to go to the after-parties but not the CMAs. We asked if it was because Miranda Lambert was going to be there and one source said, "She doesn't care if Miranda's there or not. She just didn't have the right clothes for the award ceremony because it was so last minute."

They will not be hiding their relationship tonight. We're told they'll spend a few days together in Nashville.

As for how long they've been dating ... we're told "just days."

5:14 PM PT -- As we told you, Blake's flying solo at the CMAs. Expect plenty of cutaways to his seat.

L.A. Lakers star rookie D'Angelo Russell is not keeping up with the Kardashians -- or banging one of them -- with sources telling TMZ Sports he and Kendall Jenner are just friends.

Rumors have been swirling that the two are in the early stages of a relationship ... which is why she was courtside at the Lakers game on Sunday.

But multiple sources (really good sources) tell us it just ain't true ... "They're not dating."

One source connected to the situation put it this way -- "Kendall is not into him."

We're told she was at the game because she's friends with one of the Dallas Mavericks players and his girlfriend.

Another source tells us, "They're friends, but that's about it."

Then again, that's kinda how it starts ... right?

Swipe left on the dating app Bumble and a half-naked photo of Johnny Weir wearing nothing more than a banana leaf just might pop up.

The Olympic skater was in Chicago this weekend when his Bumble profile popped up for locals. For those outta the loop, Bumble's a dating app that's pretty much the same as Tinder.

It's clear he's ready to date again following his nasty, public divorce from Victor Voronov.

Weir's Bumble profile is stark, only mentioning he's a sports commentator at NBC who loves his dog and can speak 2 languages. But when you swipe through his images, a clearer pic emerges.

He should have no problem finding a date.

"Orange is the New Black" star Dascha Polanco is back on the market, and hooking up with a woman is on the table.

Dascha ended her 6 year engagement more than 2 years ago with a non-show-bizzy guy, and she made it very clear Sunday night leaving Dos Caminos in NYC, 'OITNB' has made its mark on her.

Turns out, Travis Browne was telling the truth ... the UFC star really is in a full blown relationship with Ronda Rousey -- so says Ronda herself.

After Browne went public about it yesterday ... saying Ronda is his woman and he's her man ... Ronda issued a confirmation to ESPN saying, "It's true that Travis and I are in a relationship."

Ronda explained, "I don't talk about my personal life much. That's why it's called 'personal life" ... but added, "I've really enjoyed the time we have spent together and getting to know one another. And that's all I'm going to say about it."

The rumors are true ... Ronda Rousey is in a relationship with UFC fighter Travis Browne -- the same guy who was accused of beating up his wife -- and then CLEARED after a UFC investigation.

Browne just went on "The MMA Hour Live" and said he started talking with Ronda over the summer and their relationship blossomed.

"I'll say now that we are together," Browne said ... "She's my woman and I am her man."
