Hot Vegas

Michelle Obama looked like she was having a spankin' good time at Christina Aguilera's Las Vegas show ... especially when one of the dancers twerked on her!!!

The former First Lady attended Christina's The Xperience Wednesday night at Planet Hollywood's Zappos Theater, and got singled out by one of Aguilera's shirtless male dancers while she was in the middle of singing "Lady Marmalade."

Michelle didn't seem to mind -- she mimicked delivering some butt slaps before the guy moved on, and she continued to dance in her seat. In fact, she and her friends looked like they wanted more ... more ... mooooore.

We're told Obama and her group of gal pals were escorted out by security after the show ... seemingly pleased with Christina's performance.

As for why the ex-FLOTUS was in Vegas ... she spoke earlier in the day at the Ultimate Software Connections Conference, so apparently her ladies' night out was the pleasure after the business.

"What happens in Vegas, stays in Vegas" just doesn't apply to her.

Kevin Hart wants the judge to throw out his sex tape lawsuit ... just like he says the legal papers were thrown out of a car window and left on his driveway.

According to new legal docs -- obtained by TMZ -- the actor claims he was not properly served in the case filed against him by Montia Sabbag ... Hart's alleged sex tape partner who sued him for $60 million, claiming he and his friend conspired to tape their encounter.

Hart wants the suit dismissed because he claims the process server "simply threw a set of papers out of a car window in view of a security guard" outside the gate of his home.

The security guard's photos of the drive-by drop-off appear to show the legal papers lying on the ground outside the server's car. The security guard claims he doesn't live at Hart's residence, and wasn't authorized to accept service of a legal complaint.

Due to the improper service ... Hart wants the judge to dismiss the case.

We broke the story ... Sabbag sued Kevin back in September, alleging her 2017 encounter with him in a Vegas hotel room was all planned by Hart and J.T. Jackson -- his friend who was later charged for extortion.

The Cirque du Soleil acrobat who fell during the finale of a Beatles LOVE performance seemed to lose their grip at the height of a rope stunt -- and based on this footage, he's lucky.

We broke the story ... the Sunday night accident at The Mirage in Las Vegas, forced performers to cut the music and send the audience home early. First responders needed room in the theater to get to the guy who went down hard.

You can see in the video ... everything started off as planned as the acrobats and dancers performed to "Sgt. Pepper's Lonely Hearts Club Band" ... the stuntman elevated on the rope and came down safely twice.

The third time though, he lost control and plummeted to the ground.

After the fall, a fellow performer gave an emergency signal, but there were several seconds of confusion -- others on stage didn't know what happened, and kept the show going. It's awkward to watch, but they just had no way of initially knowing.

It's impossible to see this accident and not think of Genea Sky's 15-foot drop from a stripper pole in Texas. She suffered some brutal injuries but survived ... just like this guy in Vegas.

A rep for LOVE tells us the emergency team got him backstage and he was transported to a hospital. His injuries were non-life threatening, and they say he wants to get back ... in the show!!!

LOVE says he's doing well and they expect him to be back in the show soon.

James Harden had a front-row seat for a Desiigner performance in Vegas, but he got more than he bargained for ... 'cause the rapper fell off stage right into the NBA superstar!!!

Desiigner was in the middle of his hit song "Panda" Tuesday around 1:30 AM at JEWEL Nightclub when he misstepped. Seriously, he just missed a step and toppled off stage onto Harden's back. Chill, Houston ... you don't have a problem. The Beard and its owner were not injured.

Our sources say James was trying to keep it low-key inside the club -- he had his hoodie on when he arrived. That went out the window when Desiigner found out he was there and blew up Harden's spot.

The brush with Desiigner didn't ruin Harden's night or his All-Star break -- the Rockets are off until Thursday night. We gotta give JH props here ... for NOT flopping!!!

A super scary moment went down during a Sunday night showing of The Beatles LOVE in Las Vegas ... when one of the stunt performers took a nasty fall.

Law enforcement sources tell TMZ ... a member of the Cirque du Soleil team was injured during the show at The Mirage and transported to a hospital. Fortunately, we're told the performer suffered non-life threatening injuries.

Could have been much worse, according to witnesses, who say a male LOVE performer was doing a rope stunt at a very great height when he lost control and fell. Those in the crowd described the incident as "shocking," "just awful" and "traumatizing."

Immediately after the fall, the show was stopped due to the medical situation and the audience was asked to leave. We're told the fall happened near the end of the show.

We don't know which song they were performing at the time, but the show is packed with incredible acrobatics set to Beatles hits. It's been one of the most popular shows on the strip since opening in 2006.

A rep for the show tells us the show stopped "as a precautionary measure and in accordance with our emergency response protocols."

They continue, "As always in the case of an accident, the artist will continue to be monitored by the show's medical and coaching teams to determine when he can return to his activities."

Minnie Mouse was in no mood to be sweet with a security guard who was jawing back and forth with her ... and she wasn't shy about dropping haymakers.

The surreal scene went down on a street in Las Vegas, where a woman in a Minnie costume took off her mouse head to throw down with a woman apparently working security.

In the video, it appears the woman in the security jacket lunges at Minnie ... and it's all downhill for her after that. Minnie throws and lands a series of violent punches, before getting on top of the woman to continue pulverizing her.

Mickey tries to jump in and break it up but appears to get popped once himself ... meanwhile, Goofy mostly looks on in dismay.

Eventually, the 2 women are separated and Minnie yells, "I ain't no bitch, bitch!" before taking off with Mickey. It's a pretty stark contrast from her usual, "Aren't you sweet" catchphrase.

Law enforcement sources tell TMZ ... Vegas cops are aware of the altercation and want to speak with both parties, but there's no investigation until either of them comes forward.

UFC fighter Felice Herrig is giving TMZ Sports a blow-by-blow of her bloody Vegas street fight ... and she tells us the whole thing started over a penny.

35-year-old Herrig --the #12 ranked strawweight -- was in Sin City for UFC 246 ... when her night out on the town started to resemble her day job.

Herrig was walking with a friend between two casinos when a woman halted foot traffic to retrieve the cent.

“I was just like, ‘Dude it’s just a penny,’” Herrig told us. “And then I thought it was over and I was walking out with my friend, Kim, and she comes up from behind me and she was like, ‘It was on heads!’”

The penny-pincher declined Herrig’s request to get out of her face.

“So, I kind of shoulder bumped her to kind of let her know to go away, and she came at me,” Herrig tells us. “She punched me in the nose. I just remember punching her two times back.”

Herrig wasn't seriously hurt ... but did have her nose busted. Luckily for the woman who allegedly started beef with Felice ... she wasn't badly hurt either.

“I wanted to double-leg her, but I’m still recovering from my ACL injury,” Herrig tells us.

Felice says she doesn’t go out in public looking for fights, but she had a message for anyone else looking to start with her.

Dana White says Conor McGregor's next fight will almost definitely be a rematch with Khabib ... and the result of the match will have a major impact on the legacy of both guys.

TMZ Sports talked to Dana White outside T-Mobile Arena in Vegas after McGregor DOMINATED Donald "Cowboy" Cerrone ... and asked the UFC honcho who the Irish superstar wants next?

"Conor wants Khabib. Conor always has a lot of options. He wants Khabib, that's the fight he wants, and we'll see what happens."

We then asked White who he wants Conor to fight.

"I think Khabib makes sense too."

Khabib is scheduled to fight Tony Ferguson in April ... and if the 28-0 fighter wins, that could set up the Nurmagomedov-McGregor rematch -- and it'd be HUGE.

The only snag? Khabib and his manager, Ali Abdelaziz, have repeatedly said the Dagestani star will NOT rematch Conor.

But, Dana doesn't sound worried.

"Listen, Khabib has never turned down a fight. The guy's 28-0. He's one of the baddest dudes to ever do it," Dana tells us.

"This fight's important for his legacy too. When you start looking back at Khabib's career and if he goes undefeated and retires. You're looking at the names, and the names mean everything. He beat Conor McGregor. He beats Tony Ferguson. He beat Conor McGregor again. He beat this guy, that guy."

That's not all ... White also talked Floyd Mayweather -- who teased a Floyd-Conor II and Floyd-Khabib bout Saturday night -- and made it clear TBE still wants to fight.

Here it is ... Conor McGregor and Donald "Cowboy" Cerrone stripping down and weighing in for their main event fight at UFC 246 -- and good news, they both made weight!

Conor and Cowboy both hit 170 on the dot -- perfect weight for their welterweight matchup Saturday night at the T-Mobile Arena in Las Vegas.

The last time McGregor fought, he only weighed 155 to fight Khabib Nurmagomedov for the UFC lightweight title.

But now, he's moved up in weight and he looks pretty good -- big, strong and UFC doctors say he's in the best shape of his MMA career.

As for Cowboy, DON'T SLEEP ON THAT GUY -- Cerrone holds the UFC record for most victories, most finishes and most fight bonuses!

Both fighters will next attend the UFC ceremonial weigh-in -- which goes down later Friday in front of thousands of fans. It's usually a chaotic scene. We'll have the highlights for you right here.

O.J. Simpson's reputation as a violent convicted criminal is already SO HORRIBLE, it's basically impossible to inflict even more damage to it ... so says the Vegas hotel locking horns with Juice in a defamation case.

As we previously reported, Simpson's suing the Cosmopolitan of Las Vegas over a Nov. 8, 2017 incident in which he was kicked off the property following an alleged drunken incident at a hotel bar.

In the wake of the incident, hotel staff told TMZ ... Simpson was wasted and became disruptive, getting angry with employees ... and glasses broke at the bar.

How does Deontay Wilder feel about Tyson Fury's claim that he's masturbating 7 times a day to prep for their big rematch?! He thinks it's HILARIOUS!

"I mean, enjoy yourself," Wilder said to his heavyweight rival ... "Just use the proper lotion!"

Of course, Fury says he's giving himself TONS of self-love before their Feb 22 fight to get his testosterone levels up ... claiming he'll take any edge he can get!

Wilder thinks Fury is joking -- because 7 times a day is a tall order for anyone!

"Whatever he says is for entertainment or whatever," Wilder says ... "He wanna j*** off? Enjoy himself! Just use the proper lotion. I mean some like thick lotion."

On a serious note, Fury is predicting a 2nd round knockout of Wilder when they clash at the MGM Garden Arena in Vegas ... but Deontay says that ain't happening.

In fact, Wilder says if Fury knocks him out in the 2nd, he'll RETIRE!

Mike "The Situation" Sorrentino is not willing to dance for Chippendales despite his rock-hard abs and background as a stripper ... Sitch says the male revue can't afford him!!!

We got the "Jersey Shore" star and ex-con in New York City, and our photog asked Mike if he's ever going to follow Vinny Guadagnino's lead and join the famous production in Vegas.

Easy to see why folks think Situation and Chippendales are a match made in heaven ... the reality star is all about his abs.

There's also some history between the two ... Sitch judged a Chippendales competition back in October, but couldn't be coaxed into taking off his shirt.

And, there's this ... "Jersey Shore" alums have a history of bringing in huge box office numbers at Chippendales. Vinny was such a smashing success last year, they brought him back for an extra 6 weeks.

O.J. Simpson's hell-bent on going to trial with The Cosmopolitan, and he's evoking the name of Meek Mill to plead his case ... according to new legal docs.

Juice is trying to avoid arbitration in his lawsuit against the Las Vegas hotel -- in which he claims he was defamed -- because he argues the Cosmo's history of "intentionally and recklessly attacking well-known public figures by placing them in a false light and defaming them" warrants a jury trial.

Simpson refers to the rapper in the docs as "another African American public figure" who was defamed by The Cosmopolitan, and says the hotel was "forced to apologize" only because Meek went public with his grievances.

Essentially, O.J. wants to go public with his as well ... which is why he seeks to put the kibosh on a much more private arbitration process. According to the docs ... he also expects a jury to award him much more money in punitive damages.

As you'll recall ... Simpson was banned from Cosmo in 2017 just weeks after his prison release for allegedly being drunk and disruptive. He claims he was neither drunk nor belligerent and was falsely accused.

Meek Mill, on the other hand, was threatened with an arrest by the hotel back in May for trespassing. The rapper accused Cosmo of going to "extreme racist levels" to keep black entertainers off its property.
