Hot Vegas

Fatone started his evening by having dinner at Stack in the Mirage with wingman Aflonso "Carlton" Ribeiro. When they shifted to JET nightclub, Joey grabbed the mic started and "performing" Timberlake's hit "Sexy Back."

In mid-song, the crowd chanted for Ribeiro to add his famous "Carlton Dance" to the routine -- and he graciously obliged!

In town for VH1 Rock Honors, Prince of Darkness Ozzy Osbourne was spotted talking with Billy Bob Thornton in the show's green room -- while Ozzy's daughter Kelly acted as translator for her seldom comprehensible dad.

Kelly had a little fun on her own later, joining up with Bam Margera and his mom at a House of Blues after-party benefitting the VH1 Save the Music Foundation, along with showman Jeff Beacher ... while mum Sharon was caught posing for photos and joking around with Robin Williams. This family gets around!

As part of a Bistro Buffet promotion, when you buy a meal at the buffet, you get a free entry form ... for a free trip to Paris drawing.

Sources inside the club tell TMZ that Longoria sat just feet away from Leo Dicaprio and Kevin Connolly, who enjoyed a private raised banquette overlooking the dance floor. Jordan showed up to Eva's booth and where the towering former baller got his hug on with the petite "Desperate Housewife." Don't break her!

Rumors were flying on Friday that the rapresario had gone down in a plane crash in North Carolina -- clearly not the case though, as he was seen partying with Diddy, Nelly and Fitty in Vegas Saturday night after the De la Hoya - Mayweather bout ... which Mayweather won in a split decision.

99 problems, but his death ain't one!

TMZ obtained video of jugsy Jessica Simpson and striped Eva Longoria bumpin' and grindin' at Pure nightclub at Caesars Palace Saturday night. The gals were there to celebrate the two-year anniversary of the swanky Pussycat Dolls Lounge.

As the ladies got freaky with PCD mastermind Robin Antin, their male tag-alongs (Eva with Mario Lopez, Jessica with hair guru Ken Paves) stayed out of their way as fans and photogs snapped away at the two hotties going at it.

TMZ, easing the pain of another Monday morning. Enjoy!

The Gwen Stefani-collaborator and recent "American Idol" guest star played the pool at the Hard Rock over the weekend, and there were plenty of chicks on that jock, as he headlined a concert to welcome back the Rehab pool party. The only thing that needed rehabbing after this show was, as far as our friends at SpyOnVegas.com could tell, were Akon's drawers.

Arriving around midnight on Saturday, the no longer big O posed for photos with fans and the Pussycat Dolls -- the Vegas burlesque branch, not the "singing" group! Jack then retreated to the club's VIP area with "American Idol" wannabeen Justin Guarini.

His entourage chilled in the VIP room, sipping Grey Goose and Dom, while JET hosted a Kim K look-alike contest. Sources inside the party tell TMZ that the competition was fierce, but Ray narrowed it down to one lucky lady, who won a chance to star in Ray's next, er, film.

Do you have steak, lobster, caviar? Hell to the no! You make a beeline to the Golden Arches for a #1 with a Diet Coke (natch). Lovin' it!

To support you with your Mac Attack, you also bring along your Vegas BFF, comedian Jeff Beacher.

The couple ate with a group of friends, including pharmaceutical enemy-turned-buddy Brooke Shields, in a roped-off patio area of SW Steakhouse. Tom likes his meat!

After the meal, the group walked through the casino floor, where fans stepped away from slot machines and roulette tables to swarm the duo for photos and autographs.

"Sopranos" siblings Meadow and A.J. Soprano were hanging out at PURE nightclub in Caesars Palace late Saturday night, celebrating the final season of the HBO show. The two were seated next to each other in the club's VIP lounge, laughing while engaged in close conversation.

Sigler and Iler were later joined by K-Fed and Marlon & Damon Wayans -- talk about a random crew!

The ex-Mr. Spears hung with a bevy of blondish, er, beauties, at the Bare Pool Lounge -- the Mirage's topless sunbathing paradise -- and quickly got their drink on. Um ... just who is watching those kids?!

TMZ has learned that K-Fed and his posse drank a bottle of Jack Daniels, did a round of Patron tequila shots and topped it off with some lemon drop shooters. Everything in moderation! We're told the Fed-Ex party train was the last group to leave the poolside romp, and planned to return for more fun in the sun this weekend! How does he find the time?!

Unlike Britney, if K-Fed has a meltdown, he's already got the shaved head part down!

Federlust was snapped in TAO Las Vegas' VIP lounge last night, while moving on a pneumatically-powered, glittery-lidded fembot, with whom, we're told, he danced for 20 minutes. We're not sure whether the moment captured here was before, during or after bootyshaking, but whatever K-Fed's sayin', she ain't havin' none of it.

The Weasel was surrounded by a group of scantily clad, curvy women, as he attemped to get the crowd pumped for the party. Dropping f-bombs left and right and exclaiming "I love penises," it's fair to say Shore did a fair but random job.

Shore added some fuel to the Paris vs. Kim fire, asking Princess Dash who her favorite artist was, adding, "Don't say f**king Paris Hilton, cuz we know that's not your f**king favorite artist!"
