Hot Vegas

And yesterday outside of Crustacean in Beverly Hills, Iron Mike offered up some incredible free knowledge to the embattled boxer -- it's the best piece of advice we've heard in a long time!!!

10:34 AM PT -- TMZ Sports has now obtained the original criminal complaint filed against Tarver in Nevada in 2013 ... which shows he was charged with fraud and theft for taking out the money in 2012 and never paying it back.

According to the criminal complaint, both charges are felonies ... which means Tarver could be facing some real slammer time.

Former boxing champ Antonio Tarver never paid back $200,000 in gambling markers to the Wynn Las Vegas from a gambling binge in 2012 ... so says a lawsuit obtained by TMZ Sports.

Tarver was arrested in Florida over the weekend on a warrant out of Nevada -- the arrest documents were vague about the nature of the alleged offense.

Now, we know ... Tarver is the target of a criminal investigation for allegedly not settling several gambling markers he took at the Wynn during a 4-day gambling binge in July 2012.

According to the Wynn, Tarver took out $50k on July 24, 2012 ... another $50k on July 26 ... and $100k on July 27 ... totaling $200k.

WHAAAT! Things got way too hot for Lil Jon in Vegas last weekend -- some hot blonde chick twerked her ass off at his table ... and the rapper decided she needed to chill ... with a glass full of ICE CUBES.

The video was shot Sunday night inside XS Nightclub -- it's pretty wild ... and Lil Jon obviously knows talent when he sees it ... because the girl in the clip has serious skills.

The stripper who was fired for taking photos with Katy Perry -- INSIDE A STRIP CLUB -- has moved on to bigger and richer things ... Floyd Mayweather Jr.

The stripper -- Devon -- Instagrammed the photo Wednesday night in Vegas after randomly running into Money May ... who's worth a reported $170 million ... way more than Katy Perry.

TMZ broke the story ... Devon lost her stripper job in Santa Barbara earlier this month after management found out she'd been taking pics with Katy inside the strip club ... where Katy spent thousands of dollars.

TMZ later posted the photos.

Rapper Cam'ron kicked some dude's testicles into the back of his throat Monday night in Vegas ... and it only cost him a reasonable $20.

Here's how it all went down. Cam'ron ran into a ballsy street peddler who was playing let's make a deal -- his sign read, "Kick me in the nuts ... $20."

Cam'ron accepted the gentleman's offer and delivered David Beckham style. The street peddler collapsed in pain, Cam'ron paid his debt and went on his merry way.

Ray Allen is worth between $200 and $300 MILLION DOLLARS ... and even though it's "not smart" for the guy to play high-stakes blackjack, Ray can afford it ... so says Kenny "The Jet" Smith.

The "NBA on TNT" analyst was leaving LAX yesterday when we asked him about Allen's $10k-per-hand blackjack run in Vegas over the weekend ... a run that didn't turn out well for Ray.

"It's not smart, but it's like $100 to him," Kenny said ... "He's got enough money to probably fund the hotel."

Then, after estimating Ray's ENORMOUS net worth, Kenny dropped some serious wisdom:

"A guy who can play $10k-a-hand in blackjack, I'm not worried about him ... it's the guy who's got ten dollars and loses ... that's the guy I'm worried about."

#true.

Ray Allen was LIGHTING UP a blackjack table in Vegas over the weekend ... dropping $10k per hand at the Bellagio ... and TMZ Sports has the pics.

The Miami Heat superstar decided to try his luck with the cards on Saturday night ... and posted up at a $1,000 minimum table in the exclusive Club Prive high-rollers lounge.

You can check out his stack (don't worry, it's OK to look) ... it appears Ray was gambling with somewhere between 30 and 40 yellow chips ($1,000-a-pop).

Our casino sources who were there during the gambling run tell us Ray -- who once signed an $80 MILLION contract -- didn't have a great showing at the table ... and walked away empty handed.

Hopefully, he stayed long enough to get his free drink.

We reached out to Ray's camp for comment -- so far, no word back ... but you know somewhere, Charles Barkley is smilin'.

DON'T YOU EVER TALK ABOUT RICHARD SHERMAN'S ANKLE ... 'cause less than one week after injuring it in the Super Bowl, the Seahawks star was partying hard on it during a rager in Vegas!!!

Sherman -- along with fellow Legion of Boomer Kam Chancellor -- hit up the Chateau nightclub in Sin City Saturday night ... and cut loose, despite suffering a high ankle sprain during the Feb. 2nd victory.

Seemed like Sherman was feeling "no pain" that night -- we're guessing the gang of hot chicks following him around that night makes a man forget about a freak joint injury.

Meanwhile, Peyton Manning is still sad somewhere ..

BEHOOOOLD ... the hot blonde stripper Justin Bieber recently used as a chew toy ... in all her fake-breasted glory ... and contrary to reports, she's definitely NOT old enough to be his mom.

Sources close to the dancer tell TMZ, 26-year-old Karolina began working as a stripper in Vegas very recently after moving from Chicago -- and when Bieber quietly visited Sin City back in January (before his DUI arrest) he handpicked the bunny-tatted dancer to come back to his hotel room.

We were initially told by the owner of the photo that the pic was snapped inside an L.A. recording studio, but turns out it was actually taken inside Bieber's Vegas penthouse.

Sources tell us, Bieber and his entourage hand-picked Karolina and two other dancers to come back to the hotel room for private dances ... and Bieber paid them THOUSANDS each in cash.

As soon as they arrived to the room, we're told the girls' phones were confiscated and they were each required to sign one of Bieber's famous confidentiality agreements, barring them from talking about what transpired that night.

Our sources wouldn't say how far things went between Bieber and the girls -- but we're told Karolina voluntarily posed for the boob photo.

Shayne Lamas -- who decided to marry her hubby HOURS after meeting him at a drunken pool party -- is re-writing all the rules of marriage ... 'cause not only is she still with the dude ... they're still HAVING SEX.

We know that ... because sources close to Shayne tell us she's pregnant again.

We told you their story ... Shayne is a former winner of "The Bachelor" who fell in love with TheDirty.com founder Nik Richie 4 years ago at a wild Vegas pool party ... and hours later decided to get hitched.

NO ONE expected it to last. But Shayne and Nik are still going strong ... they have a 2-year-old daughter named Press -- and now we're told Shayne's 16 weeks pregnant with their 2nd baby.

"Transformers" director Michael Bay says his epic meltdown in Vegas yesterday might not make him popular with technology nerds ... but also says it hasn't exactly hurt him with the ladies.

Bay was on "TMZ Live" explaining why he freaked out and walked off stage during a big presentation at the CES convention.

It's not like he's never been on stage ... he says he's been front and center hundreds of times, but explains why this one was different.

Britney Spears is into 2 things -- her BF and B&D .. and she got to enjoy both at the same time during her Vegas New Year's Eve concert.

Brit dragged David Lucado on stage at Planet Hollywood ... forcing him down on hands and knees, strapping him into a harness and dog collar and then parading him around on a leash.

David seemed to enjoy it enough ... it's one of the fun perks of being with Britney.

Hours after retaining his championship belt and possibly ending Anderson Silva's career ... UFC Middleweight champ Chris Weidman continued his campaign of destruction -- by decimating a double bacon cheeseburger.

Weidman partied at Surrender nightclub -- washing down his burger with a cold Miller Lite.

UFC's other big winner Ronda Rousey also feasted in celebration ... she went with family and friends to Wolfgang Puck's restaurant at the MGM for her usual post fight chicken wings.

America!

Britney Spears blew everyone away during her Vegas debut last night ... everyone, but Katy Perry.

Katy was front and center for the "Piece of Me" show -- rubbing elbows with Miley Cyrus and Adam Lambert -- and while Miley danced her ass off, Katy couldn't seem less interested.

True enough ... Britney's no John Mayer, but come on Katy -- she's a much better dancer than him.

As they say ... you can please some of the people all of the time ...

Britney Spears got the lead out for tonight's big Las Vegas debut.

Brit's friends and family were there for her final dress rehearsal for the "Piece of Me" show ... and she did not disappoint.

Britney is back to her old self onstage ... her dance routines blew everyone away. Her singing ....

Jay Z continued his 22-day quest to eat an entirely vegan diet yesterday in Vegas ... and then partied his face off while paying tribute to Beyonce's new surprise album.

Sources at Hakkasan restaurant tell us Jay dined on strictly vegan options after his concert ... while his friends -- including rapper/producer Timbaland -- ate crispy duck salad and roasted Chilean seabass.

Afterward Jay and his entourage hit up Hakkasan's nightclub (pictured above) ... and toasted champagne to honor his wife Beyonce's surprise album when the DJ played their new collab "Drunk in Love."

99 problems but a dish 'aint one.
