Hot Vegas

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.

The UFC mixed business with pleasure in Vegas yesterday -- when the hottest ring girls and the toughest fighters stripped down to their bathing suits for a Sin City pool party ... and TMZ Sports has the pics.

It all went down at the Liquid Pool Party at the Aria to hype up UFC 189 -- where ring girls like Arianny Celeste, Brittney Palmer and Chrissy Blair kicked it with fighters like Luke Rockhold and Rumble Johnson.

Don't worry ... undefeated bad ass Paige VanZant was there too.

Scott Disick is saying NO to partying his face off -- for at least one night -- he's backed out of a paid hosting gig in Las Vegas.

Disick just made the 11th hour decision to postpone his Friday night appearance at 1Oak Nightclub in Vegas.

The decision comes on the heels of Kourtney Kardashian pulling the plug on their relationship -- and after Scott missed their 3-year-old daughter Penelope's birthday this week.

We broke the story ... Disick's friends had been urging him to cancel on 1Oak, and get into rehab.

Mariah Carey finally got billionaire James Packer on her turf -- Las Vegas -- just in time for the couple's first 4th of July together.

They shut down the rooftop deck of the swanky Mirage Villas for a Saturday evening celebration. We're told James dropped THOUSANDS to rent out the whole joint for Mariah, her managers, and Brett Ratner. This is the first time they've been together back in the States since Packer started courting Mimi during their Mediterranean tour aboard his mega yacht.

On the flip side ... Nick Cannon shared a meme addressing his single status captioned "I'm dating me."

To each his own ...

The woman who twerked with Klay Thompson in Vegas this weekend was involved in an airplane crash landing on her way back to Texas -- and moments after Klay found out, he reached out to see if she was okay.

The woman in the pool is Yara F. -- who spent the entire weekend partying with Klay and the Golden State Warriors during their victory celebration in Sin City.

After the weekend was over, Yara and some friends took a small plane headed back home to Texas -- but the jet experienced problems after take off ... and they crash landed at Lake Mead.

We spoke with Yara who tells us Klay reached out to see how she was doing after the incident -- and told her he was praying for her and the other passengers.

As for the crash, it's still under investigation -- but the good news ... no one was seriously hurt.

Bryan Cranston didn't just show up to the Electric Daisy Carnival in Las Vegas this weekend ... he brought Walter White along for the ride.

Cranston crashed the EDM festival and introduced the band Above & Beyond ... who just happened to have a song called "Walter White."

The "Breaking Bad" star growled out a few lines before ferociously dancing onstage with the group ... which he mildly regretted the next day. He wrote, "Leaving EDC—Vegas right now. Pulled an all-nighter. Old, my ass...Old, my head. Old, my feet...Happy Father's Day!"

Ruby Rose, meet ... Ruby Rose, or maybe it's Justin Bieber. Everyone has wanted to see this pic, to either end or fuel speculation that they may be the same person.

The two met up at Encore Beach Club in Las Vegas ... Ruby posted it on instagram.

Lamar Odom is turning to some famous boxers for support in the wake of the death of his close friend Jamie Sangouthai ... hanging with Adrian Broner and Zab Judah at an event in Vegas.

Odom had briefly returned to L.A. after he learned Jamie died -- and as we reported, he was taking the death very hard and friends were concerned that he would relapse.

But Odom is now back in Vegas ... and today, he was supporting Broner as the boxer weighed in for his big fight against Shawn Porter tomorrow night.

We're told Lamar has been friends with Zab for years (they're both from NY) and made plans to hang out this week while supporting Broner.

Odom appeared to be in a good mood at the event, smiling and talking to people.
