Hot Vegas

Tyson Beckford has a tip for all the ladies coming to his Chippendales shows in Vegas -- don't do what Mariah Carey did when she came face-to-face with his dong.

Tyson told our photog at LAX that even though Mimi slipped him $300 for a BIG peek at his goods last week ... that was more of an old friends with benefits situation.

The JACK DIESEL apple doesn't fall far from the JACK DIESEL tree ... and the Gronkowski family is living breathing proof.

Check out these pics of New England Patriots tight end Rob Gronkowski breakin' out the guns in Vegas this weekend ... right next to his almost-equally swoll father, Gordon!

The whole shredded family hit up the Rehab party at the Hard Rock Hotel to celebrate Rob's 26th birthday ... including Rob's bros Chris, Dan, Glenn and Gordie Jr.

BTW -- the people at Rehab gave Gronk a cake for his birthday. Can you guess what he did with it?

Mariah Carey is smiling from earhole to earhole because one of her fans -- with money to burn, apparently -- laid a cool 4 Gs worth o' jewels on the diva as a pretty sweet thank you gift.

Sources tell TMZ ... Mimi invited jeweler Eric Meier to her opening Vegas show at Caesars Palace, and to prove he's her biggest fan -- he handed her a pair of black diamond drop earrings in an 18 ct. rose gold setting.

We're told the Orion earrings are worth nearly $4k, but we're guessing he got a decent discount since they're available at his store, Diamonds Don't Lie. Still, it's the thought that counts ... as you can tell from Mariah's face.

50 Cent is smack in the middle of a criminal investigation after a guy claims 50's goons pistol whipped him and stole a quarter of a million dollars in bling.

Robert Marin, who owns LAX Jewelry Co., tells TMZ he went to Vegas during fight weekend because he wanted to sell the rapper a watch and chain worth $250K. Marin says he met 50 at Drai's nightclub, showed him the jewelry and 50 was in, but they needed to negotiate a price.

Marin says they stayed at Drai's until the wee hours Saturday and 50's crew invited him to see Floyd Mayweather's gym ... an offer he couldn't refuse. Marin claimed when they arrived things turned ugly. He says 2 of 50's guys pistol whipped him, stole the jewelry and fled.

Marin has filed a robbery report and Vegas cops are investigating.

50's people say the story is BS ... his attorney Scott Leemon tells us, “On behalf of 50, I can adamantly deny that he or his security had anything to do with these baseless and false allegations.”

When you hang with Snoop Dogg and Rick Ross on the reg, you don't take a lot of crap -- which is probably why social media sensation ATown came thiiis close to road raging on a Vegas bus driver.

ATown was getting into a rental car when it got sideswiped by a shuttle bus ... according to our sources. In the video -- shot right after the accident -- he goes looking for a fight.

Now, 21-year-old ATown's a pretty diminutive guy ... but still had to be held back by Snacks, his much bigger brother/manager.

Snacks says ATown went to the hospital to get checked out, just in case, but says other than a slightly sore back ... he's fine.

Shortly after the incident he let his fans -- like French Montana, Waka Flocka Flame, and Nick Cannon -- know he'd survived.

Mariah Carey helped out a dude in need by stuffing some bills in Tyson Beckford's underwear, and it looks like she got a load of the full Monty.

Mimi unwound on her night off Thursday and went down the strip a stretch to take in Tyson's Chippendales show at the Rio.

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.
