Dating

Nick Diaz isn't letting his domestic violence case get in the way of meeting new women -- the UFC star was out in Vegas this weekend getting hot and heavy with a new lady ... TMZ Sports has learned.

Diaz hit up XS Nightclub at the Encore Hotel on Saturday night -- where our sources spotted Nick kissing a new mystery lady right in front of everybody!!

Unclear if they're dating or if they were just having a fun night.

We're told this is NOT the woman who accused Diaz of domestic violence.

As we previously reported, Diaz was arrested a few weeks ago after another woman -- who told police she had been in a sexual relationship with Diaz for years -- claimed Diaz attacked and choked her at a Vegas home.

It's been about six months since Kendall Jenner was linked to a rumored NBA BF, but as her biking date with Ben Simmons shows ... you never forget how to date one of 'em.

Kendall was seen getting her ride on this weekend with the 76ers star point guard -- on a bicycle, folks ... relax. Eyewitnesses tell us they were cruising near The Grove in West Hollywood Sunday -- and we gotta say ... Kendall looks like the pro out of the two.

She's got solid form, AND she's got a purse on her, too, which looks perfectly in sync with her body. Much improved from 2016, when she ate s*** riding down a dirt road.

Ben, meanwhile, looks a little too big for his own bike here ... perhaps struggling to peddle, even. The dude is like 6'10", though ... maybe raise the seat next time, yeah?

Either way, it's nice to see Kendall switch up the activity for her 3rd NBA pal. Can't say we ever saw her hit the outdoors like this with Blake Griffin, or Jordan Clarkson either.

Kenyon Martin says "there's no such thing as simple flirting" anymore ... and it's all because men have crossed the line too many times when it comes to picking up women.

The ex-NBA star says he's well aware of the problems many women face in the workplace and other areas in their lives when men come on way too strong ... and it's not right.

"Over the years, men have abused their power," Martin tells TMZ Sports.

So, what happens now? Martin has advice for young men, including NBA players -- "Be smart. Notice the signs."

"No means no! Some resistance? Gotta turn away."

John Cena's desperate plea to get Nikki Bella back might've totally worked -- a month and half after calling off their engagement, the couple is working on their relationship, according to Nikki herself.

Nikki tells us they've seen each other a few times, and are trying to work things out ... day by day. You'll recall, she called off the engagement after having serious questions about their future together. John didn't want kids, Nikki did.

Cena took the breakup hard -- making red carpet pleas for her, and then going on the "Today" show to profess his undying love for his ex. As he put it, "I want to be the father of her children. I just want us to work."

Well, it's official ... Ben Simmons is 100% hanging with Kendall Jenner -- because they hit up Nice Guy in West Hollywood together on Wednesday night -- on a double date with another NBA star.

It's funny because Ben and Kendall hit up one of the most paparazzi-packed places in town -- but arrived separately so the photogs couldn't get a shot of them together.

FYI, Kendall left the restaurant around 10:45 PM to make it look like she was leaving ... but snuck back inside to hang with Ben. They both REALLY left together around 1 AM.

Still, everyone knew the jig ... especially when they left and both got into the same SUV -- along with Kylie's BFF, Jordyn Woods, who was hanging with 21-year-old rising star Devin Booker.

Of course, everybody stayed mum when we asked about relationship status -- and Ben's situation with ex-GF Tinashe ... but it's obvious the dating rumors are true.

NBA star Ben Simmons had a fancy dinner date in Bev Hills on Monday night ... and the woman in his car sure looks a lot like Kendall Jenner.

It makes sense ... considering new reports the Philadelphia 76ers star has broken up with Tinashe and moved on to Kendall. The romance has been going on for a few weeks, according to Page Six.

Our video was shot outside the Waldorf Astoria Beverly Hills -- where our sources say Simmons and the mystery woman had a bite to eat together. We're told the woman tried like hell to stay low key -- using her hoodie to cover her face.

Kendall's been connected to basketball players before -- most recently, she was with Blake Griffin and before that she was reportedly dating Jordan Clarkson.

If that really is Kendall (and it really seems like it is) ... welcome to the Kardashians, Mr. Simmons!

FYI, we last saw Simmons with Tinashe in Philly earlier this month -- riding in a Ferrari together.

Scott Disick has been tamed by a woman close to half his age.

Scott turned 35 Saturday and he spent it with 19-year-old gf Sofia Richie on St. Barts. For her part, Sofia is in hook, line and sinker, telling the world, "Happy Birthday babe! Thank you for being you. Love you."

The 2 have been together now for a year and word is they've gotten super serious.

It also looks like Scott and Kourtney Kardashian have made peace ... if only for the sake of their 3 kids.

Scott has a pilot in the works where he's flipping houses in the L.A. area with super realtor Tomer Fridman ... and guess who's behind the project? If you guessed Kris Jenner you would be correct!

Nicki Minaj just sent the internet into a frenzy, confirming she and Eminem are a couple.

Minaj has been on a social media tear lately, promoting new music and her upcoming album. She posted a clip on Instagram Thursday rapping along to her verse on YG's "Big Bank." One fan commented on the video asking Minaj, "You dating Eminem???" ... Nicki replied with a simple, "yes."

It's possible Minaj is just kidding, she mentions Em in the song, saying "Told 'em I met Slim Shady, bag the Em.Once he go black, he'll be back again."

Nicki and Eminem have teamed up before ... both appearing on her track "Roman's Revenge" in 2010.

Caitlyn Jenner and her rumored 21-year-old girlfriend were all smiles and chatting it up ... not with our photog, but it's clear as daylight they're into each other.

We got Caitlyn and Sophia Hutchins on Sunday leaving Craig's in WeHo, where our guy tried to get some clarity on the nature of their relationship. Watch ... they wait to get inside before we see their lips moving. Rumors are they're an item ... and Sophia dropped a massive hint after this pic of herself lying on a bed with the exact headboard at Caitlyn's Malibu crib.

Caitlyn Jenner and her rumored 21-year-old girlfriend appear to have shacked up together ... and the proof is all in Jenner's bed!

Caitlyn and Sophia Hutchins -- who is also transgender -- have reportedly been an item for several months. However, earlier this week Sophia dropped a massive hint as to just how serious things between the two might actually be.

Hutchins posted a photo of herself lying on a bed with the caption, "Home. Sweet. Home." Look closely ... the bed's headboard is the exact same one Caitlyn's posted many times in the past from her Malibu home.

Rob Gronkowski turns 29 today -- only 40 more years until his favorite number -- and he's celebrating with an insane trip to Jamaica with his bikini model girlfriend.

Gronk and Camille Kostek have been living it up at some super fancy resort -- eating fruit, hiking to waterfalls and busting out some sexy bikini dances (thanks for that, btw).

Gronk seems to be in a good place -- as you can see at the end of the dancing video.

The two have been connected for years -- they were serious, then took some time apart ... but now they seem to be in full swing.

No word if a ring is in Camille's future ... but it sure seems to be headed in that direction.

Khloe Kardashian and Tristan Thompson are taking their rekindled relationship to the next level ... with a daytime movie date.

The 2 were at a cinema a few miles outside Cleveland Tuesday afternoon, and looking very much like a couple again. Khloe and Tristan grabbed snacks together before the movie and were seen leaving in the same car afterward. No word on which flick they caught.

We broke the story ... Khloe's family is the opposite of thrilled about her getting back together with Tristan, but they're backing off pressuring her to dump him for good.

Ryan Seacrest's grueling "American Idol" commute ain't looking all that rough -- considering he gets to make out with his hottie gf, before AND after going wheels up.

Ryan and Shayna Taylor were out shopping and grubbing over in Venice, CA ... the day after they jetted from NYC to LA for his little $10 million weekend gig. They did lunch inside Gjelina, and did PDA outside the hot spot.

Now that all the 'Idol' episodes are live, Ryan has to make this cross-country trek every weekend. Soon as 'Idol' ends Sunday nights ... the couple hops back on a jet plane -- private, of course -- to be back in NYC for 'Live' and his radio show.

Pump the baby brakes on Blac Chyna -- 'cause she's definitely not pregnant right now, although that could change ... TMZ has learned.

Sources connected to Chyna tell us she is NOT currently pregnant with her boyfriend YBN Almighty Jay's kid, despite reports to the contrary. However, we're also told that she DOES want more kids in the future ... and isn't ruling anything out with YBN.

Chyna already has two kids of her own -- one with Tyga, and another with Rob Kardashian. If she got knocked up again ... it'd be baby number 3 for her.

Sounds like it's possible. Fact is, we're told Chyna is in love with the 18-year-old rapper, and IF she were to become pregnant anytime soon ... he's obviously first in the running as the baby daddy. As we've reported ... the couple's been seeing each other since at least February.

Stormi Webster was flying solo Wednesday night so her parents could hit the town in Houston.

Kylie Jenner and Travis Scott sat on the hardwood as they watched Travis' home team destroy the Minnesota Timberwolves.

It seems the fam is making Houston their second home ... earlier this month Travis, Kylie and Stormi flew to Texas so his family could meet their newest 2-month-old member.

The Weeknd was seen partying with a ton of hot chicks at Coachella ... but he isn't locked down by a single one.

Abel -- who headlined the festival on Friday -- was spotted with Chantel Jeffries, hanging out with Kendall Jenner and even being friendly with his ex, Bella Hadid. However, sources close to the singer tell us he's simply enjoying the single life ... and isn't serious with anyone.

Our sources say Bella was in the crowd for Friday's show and the two exchanged hellos, but any reports saying they swapped spit are totally untrue.

We're told after his performance Friday, Abel spent most of the weekend partying with his friends, family and the XO Crew.
