Hot Vegas

Hip-hop honcho J. Prince nearly came up snake eyes in Las Vegas -- losing a $75,000 diamond encrusted watch in the airport -- until a stranger came forward to save the day ... and then Prince made his.

Sources connected to the Rap-A-Lot Records chief -- and infamous Drake defender -- tell us he had just gone through TSA Tuesday night when he noticed his iced out Hublot was missing.

With $75k on the line ... you better believe Prince's crew immediately scoured the terminal - and while they were searching, we're told a dude walked up and whipped out the watch. Witnesses say Prince's security surrounded him to confirm it was the right one, and that's when the awesomeness happened.

In the video ... you see Prince walk up to the good Samaritan and hand him something. We're told he reached into his pocket for some loose change to reward the guy -- and by loose change we mean ... $500!!

So grateful. So baller. Jewelry recovery is really becoming J. Prince's thing -- right, Stevie Francis?

Mariah Carey opened in Vegas Wednesday night to a captive audience, and handcuffs were involved.

Mariah performed to a packed house at The Colosseum at Caesars Palace and her voice was in great form. She made her grand entrance on a Sea-Doo and went on to sing her 18 #1 hits.

In the middle of the show her people pulled a guy up onstage and it looked like Mariah was going to do a little S&M to entertain the crowd, but there was a twist or 2. The video is hilarious.

Lindsay Lohan's nemesis Brandon Davis blew through $300k in one amazingly awful Vegas night -- but he was gambling with casino money, and hasn't paid the debt ... so now they want payback.

Brandon -- an heir to the Davis oil fortune -- was sued by the Wynn Las Vegas and the Bellagio for unpaid markers which he got on Nov. 7, 2014. In docs, the casinos say Davis has been ducking them ever since his epic bad luck streak.

So, the Bad Check Diversion Unit of the Clark County D.A.'s Office is stepping in -- ordering Davis to pay at least $9,257/month until he's paid his tab ... which has now ballooned to $323,962.

Pretty funny -- the guy who infamously blasted Lindsay for being poor is now deep in debt. Still, it's a good excuse for a "firecrotch" #tbt.

Mariah Carey is unreal ... we got audio of her full dress rehearsal for her Vegas show which opens tonight, and she sounds as good as she did in 1990 when she hit #1 with "Vision of Love."

Mariah performed for more than an hour Monday night to a packed house at The Colosseum at Caesar's Palace, and you gotta hear it. She hits every high note and sounds flawless.

We got audio from someone in the audience ... filled with various people who work in Vegas-related businesses. We posted a minute-and-a-half and sampled 4 songs. Wait till you hear her hit the high notes in "Emotions."

As for the naysayers who claimed she wasn't rehearsing enough ... whatever she did was clearly enough.

Chris Brown's birthday celebration on the Vegas strip had bottles poppin', hot chicks dancing, and ... absolutely adorable little baby videos.

Yeah, Chris' 26th bday party at Drai's was way different from his others, because this one featured home vids of Royalty on a big screen -- and you've gotta see the look on Chris' face ... daddy's totally fallen for his baby girl.

The video is pretty wild for a few reasons -- Chris hands out Ace of Spades bottles to fans in the crowd ... Chris shows off his badass dance moves ... AND Chris spins and goes flying off the stage!

Breezy also got the champ to come out -- Floyd Mayweather Jr. showed up flashing a tiny bit of the more than $200 mil he earned at the office last weekend.

Hip-hop producer Mally Mall must be bored with love triangles -- the "Love & Hip Hop: Hollywood" star is breaking up with Nikki Mudarris again, but this time THREE other chicks are involved.

Mall and Nikki are known to be on-again/off-again (a recurring theme from Season 1) and their relationship status was set to OFF after a blowup over a Las Vegas fight weekend party.

According to our sources, the couple was supposed to host a Mayweather/Pacquiao party at a rented house in town, but Mally showed up with three chicks that weren't Nikki ... and she didn't show up at all.

Season 2 is just writing itself.

Tyson Beckford's Chippendales debut was a real banger for Sheryl Underwood from “The Talk.”

She got an up close and semi-private viewing of Tyson's junk during the show -- prompting some odd comments in our newsroom about ... proper reactions to a wiener in your face.

In the blink of an eye, Chris Brown is no longer wanted for battery.

Law enforcement sources tell TMZ ... the guy who accused Brown of punching him early Monday morning during a basketball game in Vegas called the cops on Tuesday and told them he wanted to drop the case. He did not explain why.

At that point it was a no-brainer ... cops closed the case.

If ya wanna know what Tyson Beckford's junk looks like -- ask Sheryl Underwood … because "The Talk" host got an eyeful of his manhood in Vegas this weekend.

Beckford made his Chippendales debut Friday night at the Rio -- and gave Sheryl a very up close and personal introduction to his man parts ... while slipping out of his towel and into briefs.

Watch the vid ... Sheryl might have gotten the "biggest" show, but the audience got something too.

Stephen A. Smith is obviously a close personal friend of 50 Cent ... 'cause TMZ Sports has video of the ESPN host taking the stage with Fiddy this past weekend in Vegas and ... it's funny in a good way.

50 was performing at Drai's Friday night when 47-year-old Smith hopped onstage for what we'd like to believe was an audition for membership in the G-Unit.

Check out the clip -- Stephen A. seems to have mastered "what the hell am I doing up here" swag ... 'cause 50 doesn't seem bothered with him being in the crew ... even though he looks like someone's uncle.

Ludacris hosted a pool party at the Hard Rock in Vegas where an all out brawl broke out. Fists, furniture, bottles ... everything was flying!

Absolute mayhem, and at least twice as entertaining as the Pacquiao-Mayweather fight.

Chris Brown is accused of brawling with another guy early Monday morning during a basketball game in Las Vegas -- and police have named him a suspect for battery.

The altercation went down at the Palms Casino Resort -- according to police ... Chris was playing hoops at 3:42 AM and at some point he got into an argument with one of the guys playing -- and allegedly punched him. The pickup game was being played in the famous Hardwood Suite ... where Chris was staying.

Police responded to the scene, but didn't talk to Brown when they got there.

Cops say Chris now has 2 options: either sign a citation for misdemeanor battery, and agree to show up in court to face the charge -- OR take his chances with the D.A ... who would decide whether to press charges.

TMZ broke the story ... Brown just settled a lawsuit over another fight during a pickup basketball game in an L.A. gym.

But he also dodged a major bullet -- if the Vegas fight had happened before Chris got off probation in the Rihanna case -- back in March -- he could be going back to jail.

Here's footage of boxing superstar Adrien Broner GOING ABSOLUTELY BERSERK after winning at the baccarat table in Vegas Sunday night ... yelling, screaming and AIR HUMPING the table.

It's unclear how much cash Broner had on the table in the high roller's room at the MGM Grand -- but it must have been A LOT ... because any normie woulda been kicked out of the place in a heartbeat.

The video is pretty hilarious ... Broner starts yelling about how he "f**ked this town up" with "no condoms" ... while thrusting his junk into the table.

Congrats.

BTW -- Broner's weekend was definitely eventful ... here's video of AB pounding a whole lotta tequila at a post-fight party.

At least ONE Mayweather went down this weekend ... Floyd's father ... who ate it HARD during a pre-fight concert ... and TMZ Sports has the video.

Floyd Mayweather Sr. got up onstage and did his best James Brown impression to the tune of "Sex Machine" at the Fiesta Rancho Casino in Las Vegas on Thursday.

But while he was lettin' loose -- he lost his footing ... and went crashing down to the dance floor.

The good news -- like a true pro, the 62-year-old popped RIGHT BACK UP and continued to dance ... even busting out the signature James Brown "Camel Walk" dance move.

The REAL fight in Vegas went down the day after Mayweather-Pacquiao -- a huge melee at the Rehab pool party hosted by Ludacris.

The video is absolute INSANITY -- showing multiple brawls around the pool on Sunday at the Hard Rock Hotel -- fists, chairs, bottles, ice buckets and more were hurled. Even before the fight broke out ... you can see the crowd rip a door off its hinges to burst into the party!

Jamie Foxx and Will Smith's son Trey were also at the party at some point -- though it appears they weren't involved or injured in the fight. Perks of VIP.

Here's the odd thing -- Vegas cops tell us they got no calls for this brawl. We've got a call in to the Hard Rock too.

The Mayweather vs. Pacquiao fight was unanimous in everyone's eyes, but Manny's aunt and cousins are steadfast ... the fight was fixed.

Aunt Lilia and crew were leaving the Mandalay Bay on Sunday when our photog asked whether Manny was cheated, remember the boxer felt he had won the fight. His family went 5 steps further and claimed the whole thing was rigged and people got paid off.

They weren't done... they also trash talked Floyd.

TMZ Sports got Aunt Lilia back in March when she belted out the signature tune from 'Frozen." She might want to take some advice ... let it go.
