Party All The Time

Robin Thicke and Paula Patton spent Christmas Eve partying together -- and even though they're not reuniting -- based on pics from the bash ... some of her family wishes they would.

Robin looked like the most popular guy at the holiday fest thrown at Paula's house -- and her cousin posted photos of the singer all buddy-buddy with everyone in the fam. Except Paula.

A source close to Robin tells us it was totally normal for Paula to invite Robin because of their kid, Julian. But c'mon -- look at the photos -- it's not normal for her family to show him so much love.

Christina Aguilera is not in the Christmas spirit ... she spent her birthday in "The Happiest Place On Earth" ... in a heated argument with Mickey Mouse ... TMZ has learned.

Our theme park source tells us while ringing in her 34th b-day at Disney California Adventure, Christina and her crew tried to get a pic with Mickey, but he was going on a break ... so Christina was told she had to wait. Cue meltdown!

Aguilera lost it, and called Mickey an "a**hole." We're told she even dropped the dreaded, "Do you know who I am?"

Xtina's crew started hurling threats, we're told ... and Mickey had to be ushered to a safe zone -- out of public view. Security was called, but by the time they arrived ... the former Mouseketeer had already split.

Aguilera's rep had no comment.

Here's video of Los Angeles Lakers part-owner Jesse Buss stumbling out of a Hollywood nightclub early Monday morning ... and it sure looks like he stopped to pee on a dumpster on the way out.

The 26-year-old -- who is also the team's Director of Scouting -- was being helped out of Greystone Manor by friends just after 1AM when he stopped ... and spent some time pressed against a dumpster in the parking lot.

So, was Jesse taking a whiz?? You can see what appears to be the classic "dip and zip" move as he finishes up ... but we can't be certain.

Eventually, Jesse finishes up whatever it was he was doing and makes his way to a car ... and a flock of attractive females follow. It appears some got in the car. One was definitely turned away.

Kris Jenner had her first XMAS bash as a single woman ... lots of friends but notable absences.

There are reports Kim and Kanye were no shows, but take a look at the 2 pics of Kim and Kanye separately in what looks like the photo booth inside the party.

Khloe shook her ass, Kendall sexed it up, and we'd say Kylie did the same but she's 17.

Bruce was a no show ... ditto Rob, Brody and Brandon.

The bash was thrown at Kris' Calabasas mansion, where she had a giant tent constructed and laced with XMAS lights.

Is Kris Jenner the happiest person you've ever seen who went through a divorce?

10:45 AM PT -- Turns out Bruce did show up to the party ... and snapped a pic with his daughters.

Step 1 -- Take care of business in L.A. by railing on Sony for caving to the hackers.
Step 2 -- Go to Los Cabos, Mexico with new wife Amal Alamuddin, Rande Gerber and Cindy Crawford.
Step 3 -- Have lunch outside with an unmistakable promotion for your tequila ... so when you get papped it's actually good for business.
Step 4 -- Revel that you're George Clooney and no one else is.

Matt Barnes rebounded from a crappy night on the court by hanging with Rick Ross and a bunch of other hip hop stars at a huge Hollywood after party.

Barnes was in the VIP at Supper Club for Rick's performance Saturday night in Hollywood. The Clippers star chilled with Rick, Wiz Khalifa, Mally Mall, and Ty Dolla Sign. Famous booty model Rosa Acosta, "Love and Hip Hop" star Sincere, and singer Anjali World (daughter of Kings owner Vivek Ranadivé) were also there.

Earlier that night ... Matt put up a goose egg in 26 minutes on the floor in the Clippers game against the Bucks, but still won ... 106-102.

Usain Bolt deserves a gold medal for what he pulled this weekend -- hitting up 3 massive parties in one day ... and doing it in a style worthy of the Fastest Man on Earth.

Bolt went on a tear through Kingston, Jamaica on Saturday -- ending the night at the Fiction Fantasy nightclub bash where he booked up the entire VIP section for himself and his entourage.

Sources at the club tell TMZ Sports ... Bolt bought more than 20 bottles of champagne for everyone partying in VIP.

Our Kingston sources say Bolt started the day at Maiden Cay -- an off shore party, only accessible by boat. Hours later Boltfest moved to downtown Kingston at the Cabana City outdoor party ... and finally crossed the finish line at Fiction Fantasy.

By the way ... looks like Maiden Cay is Usain's spot. We found several pics of him partying there year after year.

Welcome to Jamrock!

Rick Ross pulled out his bone inside a room full of people and shamed all the other dudes standing nearby -- including Wiz Khalifa -- and it wasn't even close.

Ross performed Saturday night at Supper Club in L.A. -- where Sincere Show from "Love and Hip Hop Hollywood" was hosting the event. Wiz came by to show some love and support Ricky Rozay.

Support aside, Rick just needed help inhaling that massive joint.

There's a reason they call him the boss.

French Montana, Tyga and Scott Disick found some common bonding ground ... at a lingerie party in Hollywood.

The boys were there alongside Chris Brown, Snoop, Sean Kingston and Matt Barnes. VH1 "Love & Hip Hop: Hollywood" star Sincere Show served as hostess for the Facet Studio Black Tie Lingerie Party ... which required men to dress up and the ladies to dress ... with not much at all.

Scott's presence was a little surprising ... he just became a third-time dad this week.

Miley Cyrus and Patrick Schwarzenegger took Miami by storm together, but don't get it twisted -- one of them is fueling that party train more than the other... according to their pal Cody Simpson.

The Aussie pop star was shopping at Cotton On in Santa Monica, and talking about his New Year's party plan (he's got a great one) ... which got us on Patrick, Miley, and Cody's raging times at Art Basel last week on South Beach.

We asked who goes harder in the club -- and he backs up what TMZ first told you a couple weeks ago.

You gotta hear Cody gush about Patrick though -- bromance in full bloom.

Not everybody was hatin' on Taylor Swift's celeb-crammed 25TH b-day bash in NYC -- a toy company just made a crap ton of money off it thanks to Justin Timberlake.

Turns out the takeaway from Taylor's now famous IG shot -- with Beyonce, Jay Z, Sam Smith, Haim, and JT -- was the poop emoji mask on Justin.

The people who make JT's turd face say they've seen a huge spike in sales since Taylor posted the shot. A rep for BigMouth Inc. tells TMZ they've seen a 315% increase and are almost sold out.

So, yeah ... #2 is now #1 on the charts.

It's unclear how Taylor Swift has time to learn the lyrics to EVERY song -- in addition to her own -- but she does ... and she unleashed her super fan lip-sync skills on Justin Timberlake this weekend.

Swift hit up JT's show in Brooklyn Sunday night to cap off her birthday weekend. T-Swizzle went into flailing arm mode, and not only sung along, but acted out every song too.

Legendary graffiti artist Alec Monopoly is used to displaying his work on large objects, but now he has downsized ... to Miley Cyrus.

The two were hanging out this weekend in Miami during Art Basel when he decided to draw on Miley's right leg. Nothing crazy ... just his name.

And you gotta hear Miley ... she sounds, well, like she's having a good time.

Pics of Miley later in the evening show he may have gotten a little more creative on her left leg ... though it's hard to say.

Assuming Miley showers, that should wash off just fine.
