Party All The Time

Rande Gerber and George Clooney just locked up their Boss of The Year awards with a booze-filled trip to Mexico for their Casamigos employees.

The tequila jefes flew about 50 staffers down south for the company's holiday party at El Dorado Royale resort in Cabo. George couldn't make it due to his side gig -- filming a movie -- but looks like Rande and co-owner Mike Meldman more than held down the fort.

It wasn't all fun and games on the beach though. They also had to board the Casamigos yacht.

No, we don't know where you apply.

Kylie Jenner played dress up by putting on much LESS clothing, and it was all for Christina Aguilera. Sorry, Tyga.

KJ made an encore appearance in her Xtina costume at Aguilera's 36th birthday party Saturday night. Kylie dressed like Christina from her "Dirrty" days of 2002 ... just like she did for Halloween.

Normally, it's a serious faux pas to repeat a costume, but Kylie says Christina made a special request. Plus, they kissed on camera.

No tongue, but we're still good. She should wear this every night, actually.

Floyd Mayweather was gonna make $35,000 for 90 minutes of work at a Vegas nightclub ... but blew it off because he didn't feel like leaving Europe ... this according to a new lawsuit.

Mayweather's being sued by the SLS Hotel in Vegas -- which says they had a deal with Mayweather to host his 39th birthday party at their Foxtail Nightclub on February 20.

All Floyd had to do was show up ... host the party and do the red carpet -- and bam, easy $35,000.

The SLS says he even got half the money in advance.

Problem is ... Floyd allegedly bailed at the last minute so he could "stay in Europe for his birthday."

Obviously, the club was pissed ... and demanded the advance back, which Floyd has allegedly refused to fork over.

The SLS is suing for the money back -- plus additional damages.

Kirk Douglas celebrated hitting the century mark, surrounded by a several generations of family and Hollywood friends at the Beverly Hills Hotel.

The Hollywood legend partied with his wife, his son Michael and Catherine Zeta-Jones, their kids, Steven Spielberg, Don Rickles and many more Friday night.

No word if the guests each stood up and yelled, "I'm Kirk Douglas!" -- but that would've been cool. Happy 100th!

Fun fact: The Beverly Hills Hotel opened 4 years before Kirk was born.

GQ had its Men of the Year party in L.A. Thursday night ... but it was the women there who really drew stares.

The shindig went down at the Chateau Marmont in WeHo, where Hollywood's finest showed up in full force ... especially its loveliest ladies. Among them were Charlotte McKinney, Karrueche Tran, Christina Milian, Keke Palmer, and other beautiful dames.

"MythBusters" star Grant Imahara just busted another myth ... nerds do score hot chicks, and he put a ring on his to seal the deal.

Grant popped the question to his longtime GF, Jennifer Newman, Wednesday night at Clifton's Cafeteria in downtown L.A. Most of the 250 guests thought they were there for Jennifer's surprise bday party, until Grant got down on bended knee.

As for the ring, it's a vintage 1.56 carat sparkler Grant found at an antique dealer in San Francisco for around $20k.

No wonder her answer was "F*** yeah!"

PARENTS NIGHT OUT!!!

Iman Shumpert and his smokin' hot wife, Teyana Taylor, hit the strip club TOGETHER Tuesday night -- gettin' their lap dance on with some of the hottest women in town ... and TMZ Sports has the footage.

It all went down at Aces New York -- where rapper A-Boogie was celebrating his 21st birthday ... and Iman and Teyana rolled through to join the celebration.

We're told the couple dropped a couple thousand on bottles -- PLUS the "couples twerk" session ... because, hey, why the hell not?

As for A-Boogie, we're told he dropped $5k on Ace of Spades champagne and Patron.

You win, you celebrate ... at least if you're Dak Prescott and Ezekiel Elliott.

The Dallas Cowboys superstars hit up So & So's in Dallas on Monday -- where they celebrated their 11-1 record by popping bottles of champagne while clubgoers threw stacks of cash.

Good times had by all ... and from what we're told by multiple clubgoers, no drama of any kind.

It ain't the first time the rookies have clubbed together after a big win -- they've been seen victory partying at a couple different spots this season.

It's not like they're trying to hide it -- so we're guessing as long as they keep dominating, they can keep celebrating.

Johnny Manziel turns 24 on Tuesday ... and he's celebrating with a relaxing, peaceful vacation in Miami.

Just kidding ... he's pounding booze at 8 AM.

The ex-NFL quarterback has been partying in Miami for the past couple days -- probably because Miami is poppin' right now due to the Art Basel event that takes over the city.

He's dancing on yachts, he's hanging with celebs, he's been chillin' at fancy hotels.

Dave Chappelle and Courtney Love put on a smoke show in Miami.

Dave and Courtney -- ciggies in hand -- partied this weekend in South Beach -- first catching a Madonna concert, then hitting up an after party at the Faena Hotel.

DJ Khaled's a key figure who requires da best of everything ... especially when it comes to telling time.

The rapper celebrated his 41st birthday over the weekend at Komodo Miami hosted by Haute Living. He was surrounded by da best of friends ... including Hublot CEO Ricardo Guadalupe who gave him one of the ballest presents EVER.

The new bling -- valued at upwards of $100k -- featured his "major key" logo on each side and it was decorated with "We The Best" on the caseback. And don't bother trying to cop a similar watch ... it's definitely a special edition -- as in 1 of 1.

And he had fun showing it off.

Kellyanne Conway lifted Donald Trump all the way to the White House, but there's one thing even Superwoman couldn't do -- get the Prez elect into a costume.

Trump's campaign manager slipped into a tight and leggy Super outfit herself for a "Heroes and Villains" bash thrown at Robert and Diana Mercer's family estate on Long Island Saturday night ... which Trump attended too.

Tight as the Prez elect is with Conway and the Mercers -- their daughter Rebekah's on his transition team -- he wasn't down for playing dress up at the annual event for the super-rich.

Other guests in costume included a Tonya Harding, a Cruella Deville and at least 3 Ruth Bader Ginsburgs ... according to Bloomberg.

Not a single Kryptonite-colored Hillary costume though. That would've killed.

Oscar De La Hoya has proclaimed himself single -- which apparently means his longtime marriage to pop singer Millie Corretjer is down for the count.

Paris Hilton and vodka did NOT go well together for once when a spilled drink screwed up her DJ gig in Miami -- but at least the crowd got to watch her play handywoman.

P was doing a set at Wall for Art Basel, and just when she had the club jumping ... someone doused her laptop with booze!

She was cool about it at first, but check out Paris filling time and trying to direct repairs. Somehow they got it sorted out after about 10 minutes.

DeSean Jackson turned 30 years old Thursday ... and he celebrated by raging his face off at a D.C. nightclub ... chugging champagne, taking shots and rocking more jewelry than Tiffany and Co.

The Washington Redskins superstar hit up Sax -- a super gaudy, gold-everywhere, over-the-top club -- where he celebrated with the likes of Wale and 'Basketball Wives' star Laura Govan.

Jackson broke out his fancy jewelry and his fancy Maybach for the occasion and turned all the way up.

Our advice ... HYDRATE! Just 3 days 'til DJ takes on the Arizona Cardinals.

Creating Gigi and Bella Hadid should be enough to get you into ANY party -- especially a Victoria's Secret after-party -- yet their dad still got shut down in Paris Wednesday night.

If Mohamed Hadid was on cloud nine after seeing his daughters work the V.S. Fashion Show catwalk ... that ended abruptly when he tried to party with them. As we've reported, security was super tight for the massive event, and Mohamed had to wait out in the cold.

Eventually, a publicist came out and apologized for the embarrassing situation, and Dad got to hang with his gorgeous kids.

Tip for Mohamed -- keep a wallet-sized family shot handy at all times.
