Hot Vegas

AWESOME VIDEO ALERT ...

TMZ Sports is about to show you NFL legend -- and MMA fighter -- Herschel Walker dressed as Lady Gaga and dancing to "Luck Be A Lady Tonight" in front of a packed house in Las Vegas.

It happened Thursday night in Sin City when master ventriloquist Terry Fator called Herschel up on stage during his show at the Mirage ... and what came next was so epic, you just need to watch.

Celine Dion is back on the Strip -- after a year-long hiatus she returned to her Las Vegas residency at Caesars Palace.

The Colosseum was sold-out for CD's first show since last summer ... when she stepped aside to take care of her ailing husband, Rene Angelil, who's been recovering from cancer.

The 47-year-old still nailed the high notes while running through hits like "Because You Loved Me" and "My Heart Will Go On."

Celine's scheduled to do 40 shows between now and January ... for di world!

Kevin Federline has a devious plan to kick everyone's ass in his fantasy football league ... and it involves naked women and lots of vodka.

K-Fed typically hosts the fantasy football draft at his home, but this year he's decided to bring league members to Vegas. The draft will take place August 29 at the Crazy Horse III Gentleman's Club, where he's DJing.

Now here's the plan. Kevin doesn't drink anymore, but the other guys drink plenty and he's banking on them going into full intoxication mode, giving him a clear-minded advantage. He's also banking on the guys getting distracted by naked chicks, although Kev's not immune from that either.

Travis Scott beat on security guards at his concert to protect an extremely unruly fan, and it was all caught on video.

Scott was performing at the SLS in Vegas Tuesday night when a fan in the front row tried clawing his way on stage. Security stepped in, presumably to protect Travis. But the rapper turned on them.

The situation escalated as more guards got involved and Travis got more aggressive.

Richard Jefferson likely dropped some of his new Cleveland Cavaliers dough on a craps table in Las Vegas, where he was hanging with his ex-teammate Luke Walton -- and hauling in the chips.

Vegas sources tell TMZ Sports the former U of A Wildcats were doing some serious high rolling at Aria last weekend ... wagering anywhere between $600 and $1,000 on each roll. We're told Luke walked away with about $20k in winnings, and Richard did even better.

Talk about a great guys' weekend -- we got video of the duo boarding a Southwest flight for Vegas, and they told us the real reason for the trip ... their fantasy football draft.

Jefferson's got a good shot at his first NBA championship after signing with LeBron and the Cavs -- and, of course, Walton just won his 3rd title (as a Golden State asst. coach). But sounds like all the weekend smack talk was about their FF championship.

DeAndre Jordan was heckled on his way out of a Vegas pool party this weekend -- with people telling him he sucks and the Clippers suck as he left Wet Republic with Kevin Durant.

TMZ Sports spoke with Aloun Siharath -- a Vegas promoter who was walking with Jordan's entourage as they left the pool party at the MGM Grand ... who tells us Jordan and his pals were cool, calm and collected and never let the hecklers bother them.

In fact, in the video you can hear people yelling for security -- but we're told the situation didn't get to a point where anyone was arrested.

Jordan and Durant continued to party -- hitting up various nightclubs and parties ... and even hanging with former Clippers star Matt Barnes.

A massive fire erupted Saturday at The Cosmopolitan hotel on the Vegas Strip.

The entire pool area was consumed by flames sending guests scurrying for safety. At least one person has been reported injured.

Willie Nelson is scheduled to perform tomorrow night ... no word on whether the fire will have an impact on the show.

Scott Disick is in full-on single mode, partying in Vegas and making lots of bank at the same time.

Scott raked in $50K for his appearance Friday night at 1Oak at the Mirage in Vegas. He was heavily guarded ... the only ones able to penetrate security were pretty girls.

Scott left alone but his party pal Mally Mall breezed out in a party bus with 40 of his closest friends ... all extremely female.

Meanwhile, back at the ranch, Kourtney Kardashian Instagrammed this pic of her watching Scooby- Doo with her kid.

Different ways to spend Friday night.

LeSean McCoy will not be denied access to smoking hot chicks -- even though the Buffalo Bills are crapping on his "females only" party -- he found plenty of hot chicks on the Vegas Strip.

'Shady' looked like the main attraction while partying last week at Encore Beach. We just got these pics of him hanging out shirtless and posing with every bikini babe within arms reach.

The Bills new RB got in hot water with team officials on Thursday for using the Bills logo on an Instagram invite to a party -- strictly for chicks. The party was scheduled for Sunday night, but it's unclear if it's still a go.

Juan Pablo was up to no good in Vegas -- at least that's the way it seemed --- cavorting with a soon-to-be bride until all hours of the morning.

The most hated bachelor ever on "The Bachelor" was prowling around The Bank Nightclub at the Bellagio last Saturday, when he spotted a bachelorette party ... not the show, just random chicks.

Juan was like a heat-seeking missile, zeroing in on the bride, taking her on the dance floor where he got all handsy and grindy.

But Juan wasn't done. He invited the entire party to his table, but they all declined ... except the bride. We're told the 2 of them drank and danced until 4 AM.

Jeff Dunham does his best work with dummies -- but he knows a cheap knockoff of his most famous puppet when he sees one ... so, he's taking some clown to court.

According to court docs, the famous Vegas headlining ventriloquist is suing Anthony Horn for making bootleg merchandise that looks eerily similar to Jeff's co-star … Walter the Dummy.

He says Horn has been selling counterfeit merch online -- for anywhere between $350, on up to $1,000. He fired off a cease and desist earlier this year, but says Horn would not stop.

Jeff says he created Walter back in 1987, and filed to trademark him in 2010. He's suing for all the profits from the knockoffs, and best of all ... he wants all of them destroyed.

Bonfire of the Walters, coming soon ... if Jeff wins.

The newly crowned Miss USA, Olivia Jordan, is hot as hell … a not-so-well-hidden secret Vegas discovered when she stripped down to a bikini to win a different title.

Olivia won the Luli Fama Swimwear Model Search at Wynn's Encore Beach Club back in 2014 -- and took home a giant $25k check, and a modeling deal.

Previous winner Nina Agdal was also there ... and posed with Olivia and the runners-up for a smoking hot winners circle shot.

We're guessing they skipped the interview round for the Vegas competition. Hint, hint ... organizers of Miss USA and every other stupid beauty pageant.

Here's proof Conor McGregor wasn't the only UFC star who won in Vegas this weekend ... check out fellow MMA head-basher Nick Diaz posing with a trophy of his own.

Nick was in Vegas this past weekend for the big fight and hit up Wet Republic at the MGM Grand where he seemed to have both hands full ... with a super hot chick.

Turns out the woman in the bikini is named Heather -- and she's been close with Diaz for a while now.

UFC badass Conor McGregor kept the Irish party train rollin' on Sunday -- extending his UFC 189 victory party to a crazy Vegas bikini party ... TMZ Sports has learned.

It all went down at the Foxtail Pool Club at the SLS Hotel ... where a barely bruised McGregor took in some sun with UFC ring girl Arianny Celeste ... while Ty Dolla Sign took care of the music.

Amazing McGregor even made it out Sunday -- considering he was partying his face off the night before ... hitting up Vegas nightclubs hours after he beat up Chad Mendes in UFC 189.

Guess he can sleep on the plane.

To the victor, GOES THE WHISKEY!!!

Don't EVER play poker with the guys from "Everybody Loves Raymond" -- especially Brad Garrett ... who's CRUSHING it at the World Series of Poker ... outlasting one of the best players in the world.
