Dating

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."

She's partied with him all over the world ... and was recently spotted at his game ... but Karrueche Tran tells TMZ Sports she's definitely NOT dating soccer superstar Memphis Depay.

But watch the video ... it's not the most convincing denial we've ever seen.

Tran first hung out the Manchester United stud in Miami back in June -- and was spotted in the crowd at one of his games just a few weeks ago.

But when we saw Chris Brown's ex-girlfriend out at Beso in Hollywood this week ... she insisted they're nothing more than friends.

Bella Hadid, The Weeknd, Gigi Hadid and Joe Jonas celebrated Bella's 20th birthday in NYC.

The 2 couples went to Nobu restaurant in Tribeca Friday for the occasion.

Scott Disick just took his talents and his relationship with blonde model Lindsay Vrckovnik to South Beach.

They started hanging out in New York this week, but looks like Scott's gonna hang on to her for at least a few more days ... since their all-nighter turned into a weekend getaway.

32-year-old Disick and the 18-year-old model, who just graduated high school (congrats!) were in Miami cruising from the schmancy Setai Hotel to the beach.

We're told Scott was very flirty with his new lady friend, and spent hours on the beach together.

At least he's spending time with a kid ... just not his own.

Travis Barker and Rita Ora are dating, Travis' rep confirms to TMZ.

We're told the couple's so smitten with one another they've spent almost every day together since hitting it off at the Power 106 All Star Celebrity Basketball Game in LA.

That was 10 days ago ...

Big step for Serena and Drake ... the tennis star jetted up to Canada for the opening of Drake's restaurant Monday night -- and hung out with the rapper's mother!!

Drake was in Toronto to launch his new eatery Fring's ("I got onion rings, gotta lotta onion rings") ... along with the two ladies in his life.

Serena looked smokin' hot -- high heels and a pencil skirt -- and according to people inside, there was the usual restaurant PDA with Drake.

Unclear how much time Serena spent with Drake's mom -- but we're told the music was so loud inside, it would have been tough to have that "So, you're dating my son" conversation anyway.

As for Drake, he posted a pic from inside the restaurant with his mom ... calling her his "one and only."

No word if Drake's dad showed up -- after we spoke with him last time, seems he was also waiting for some quality time with his son's new boo.

Rihanna and Travis Scott were like two dogs in heat early Friday morning at her Fashion Week after-party ... making out, grinding and dry humping each other as if no one was watching.

Fact is ... they were openly and notoriously affectionate in front of a room full of people.

The two have been hanging out in NYC this week, fueling rumors they've hooked up ... but this video pretty much confirms it.

Britney Spears hit the town Friday night with a new man.

Brit was at Iroha Sushi in Studio City with restaurant tycoon Harry Morton. First date, we're told, but a date nonetheless. If the Morton name sounds familiar it's because Harry's the grandson of Morton Steakhouse founder Arnie Morton.

Harry's been linked to some of Britney's contemporaries. He once dated Lindsay Lohan. That one didn't go well. He claimed she flooded his West Hollywood condo out of revenge.
