Party All The Time

Kylie Jenner's 18th birthday party almost got really, REALLY awkward when her parents ended up in the same booth ... with Kris Jenner's boyfriend!

We got these pics from inside Sunday night's bash at Bootsy Bellows -- and you can see Kylie, her sisters and their significant others all having a great time. But poor Corey Gamble ... at one point in the evening he became the meat in a Kris-Caitlyn Jenner sandwich.

Jennifer Aniston and Justin Theroux had a surprise wedding at their Bel Air mansion last night -- telling all their celeb pals it was just a birthday party, but then did the deed, instead.

Our sources say Jen told friends she was throwing a surprise 44th bday bash for Justin. Great cover, and friends like Howard Stern, Chelsea Handler, Sia, Lisa Kudrow and John Krasinski showed up -- but TMZ knew something was up Wednesday afternoon when we spotted a very wedding-ish cake going into the house.

It had TWO muppet-like characters -- male and female -- on the top. If it was just a birthday party for Justin ... why have 2 people on the cake?

Second major clue -- an actual man of the cloth! A pastor WITH bible in hand was walking into the house.

We're told a giant shed was built over the past week to hide all the furniture and party supplies -- which were set up in the backyard yesterday afternoon. Jen went to great lengths to keep everything under wraps -- we're told staffers' phones were confiscated all week, and no parking was allowed near the property.

Mazel tov!

Sam Smith might sling mellow R&B songs but he played up the rock star role Tuesday night after he held the after-party for his Red Rocks concert in Colorado ... miles away in LA.

Following his sold-out gig at the Denver-area amphitheater Smith wanted to rage at his favorite LA watering hole … the Abbey, so he boarded his private jet and had a table waiting.

We’re told Smith got to the famous gay bar around midnight… impressive considering the Red Rocks concert started at 8 PM and it's a 2-hour flight to LA from Denver. He also made up an hour traveling westward.

Smith brought his band along for the ride and partied till 2 AM, before calling it a night and leaving a huge tip.

He's got another show tonight in Utah ... party in Vegas?

Meek Mill doesn't need any more celebrity beef ... but he just got Justin Bieber, Khloe Kardashian, Nicki Minaj, Chris Brown, and French Montana wrapped up in a lawsuit because he is refusing to play ball ... TMZ has learned.

Meek's friends were just added to the ongoing lawsuit against him for allegedly trashing a Beverly Hills rental pad during an epic Grammy party. The owner of the house says he had warned Meek about having ragers ... and having more than 6 people on the property at once.

The lawyer for the owner tells us Meek is refusing to negotiate a payment for the damage ... so they're amping it up by naming all the high profile guests from the bash, calling them trespassers.

We're told the lawyer plans on deposing the celebs ... grilling them about the party and their involvement.

We're guessing this one's gonna settle.

Rihanna went hard in the paint over the weekend in her native Barbados.

It's called Foreday Morning Jump Up, an annual street party that starts the night before and finishes off with a sunrise paint fight ... which we gotta say, sounds like a blast and right up RiRi's alley.

RiRi came locked and loaded with a water gun in one hand and bottle of yellow paint in the other, but still managed to get caught in the crossfire.

Luckily ... her daisy dukes took most of the blows. She didn't keep them on for long though. RiRi cleaned up real nice ... opting for more traditional party attire later when hopping on a Carnival float.

Electric Zoo festivalgoers who dropped $439 for a VIP wristband have nothing on Instagram kingpin Dan Bilzerian ... because he’s taking VIP to a new stage ... literally.

Bilzerian dropped $654,400 on his Amex Black card for a VIP deck at New York's Electric Zoo … one of America’s premier dance music festivals.

We’re told this isn't your average VIP experience … Electric Zoo is building out a deck for Bilzerian with tables that will hold up to 200 of the playboy’s guests. Most of the bill is liquor-related … which will total up to $500k.

The sweetest part of the deal … the personal firework/pyro controller that he’ll be able to launch whenever he’s feeling that epic techno build to headliners Above & Beyond and Chemical Brothers.

In other words … it’s good to be friends with Bilzerian.

Kylie Jenner's turning 18 on Aug. 10th … but a celebration in the States is problematic, so we've learned she's headed to Canada to get legally wasted!

Kylie’s throwing a rager at Beachclub Montreal. It's Canada’s answer to Ibiza … a mini party island with a beach, pool, A-list DJs and lots of booze.

Here's the best part ... Kylie's being paid to celebrate her own birthday, and paid well ... we're told between $100k and $200k, just for showing up.

The club's owner, Olivier Primeau, is pulling out all the stops. Kylie will be choppered in, landing on a luxury boat that will dock next to a table stocked with bubbly. She'll also celebrate with a $3k cake.

That's not all that's legal in Canada at 18. Happy birthday ... Tyga.

"Game Of Thrones" has a fan base as big as a White Walker army, and one of those fans just threw away a ton of dough at a failed attempt to impress Khaleesi's right hand girl, Nathalie Emmanuel.

Nathalie, who plays Missandei, was clubbing it up with her gal pals at London hotspot China White last Saturday ... when a wealthy mega fan at the club dropped $55k to party with her, with the help of 12 bottles of Dom and a 6 liter bottle of Belvedere, which he sent to her table.

The mid-40s fanboy also commissioned a personalized show in which he controlled club lights and a CO2/confetti cannon.

Problem is, Nathalie wasn't impressed and sent the booze back.

A true fan would have known, such tactics would have only worked on Cersei Lannister.

Michael Jordan's got moves!!!!

His Airness put his wobble on display at Barley Mash nightclub in San Diego this weekend in front of a packed house ... and the 52-year-old proved his greatness extends to the dance floor.

Check out the video ... Jordan also hits the bar for a shot -- and continues to dance his face off ... while some guy shamelessly tries to dance over into his space. It's pretty funny.

As we previously reported, Jordan was in full clubbin' mode -- hitting up Parq nightclub earlier in the night with his wife and Dwight Freeney, sippin' on $4,000 tequila.

Michael Jordan hit the club in San Diego this weekend ... dancing his face off and sipping VERY expensive tequila ... and TMZ Sports has the footage.

MJ and his wife -- along with NFL star Dwight Freeney -- rolled up to Parq Restaurant & Nightclub on Saturday night where he got his own private VIP area ... with security watching his back the whole time.

We're told Jordan was drinking a bottle of Clase Azul Ultra tequila ... which runs roughly $4,000-a-pop inside the club ... because he's frickin' Michael Jordan and money is absolutely no object.

At one point, he grabbed a flashlight and started messing with one of his friends while dancing to Big Sean's "Blessings."

Scott Disick is in full-on single mode, partying in Vegas and making lots of bank at the same time.

Scott raked in $50K for his appearance Friday night at 1Oak at the Mirage in Vegas. He was heavily guarded ... the only ones able to penetrate security were pretty girls.

Scott left alone but his party pal Mally Mall breezed out in a party bus with 40 of his closest friends ... all extremely female.

Meanwhile, back at the ranch, Kourtney Kardashian Instagrammed this pic of her watching Scooby- Doo with her kid.

Different ways to spend Friday night.

Kylie Jenner should have been the focus at her graduation party Thursday night, but Khloe Kardashian's ass hijacked the event.

Kylie, along with her family and a few friends, celebrated KJ's graduation with a kick ass party at Kris' house. Kylie, who was homeschooled, received her diploma from Ryan Seacrest.

Kylie and Kendall are close, but who knew this close ... though it wasn't quite as awkward as the infamous "reach around video" ... but still.

Juan Pablo was up to no good in Vegas -- at least that's the way it seemed --- cavorting with a soon-to-be bride until all hours of the morning.

The most hated bachelor ever on "The Bachelor" was prowling around The Bank Nightclub at the Bellagio last Saturday, when he spotted a bachelorette party ... not the show, just random chicks.

Juan was like a heat-seeking missile, zeroing in on the bride, taking her on the dance floor where he got all handsy and grindy.

But Juan wasn't done. He invited the entire party to his table, but they all declined ... except the bride. We're told the 2 of them drank and danced until 4 AM.

Paris Hilton made a triumphant -- and soaking wet -- return to her summer home ... reminding us why they keep paying through the nose to bring her back to Ibiza.

Hilton was the main attraction Saturday night at Amnesia's Foam & Diamonds party, where she'll be DJing every Saturday night for the next few months. We're told the club owner said last weekend's opening party was the biggest money maker, so far this summer.

Paris' millionaire BF, Thomas Gross was there, and bought out the entire VIP balcony for himself and friends. Not to be outdone, we're told someone from Dubai came in and dropped $100k on endless bottles of Cristal.

The party went on til 7:30 AM and was capped off when Paris doused the crowd with foam from above. But the most fun part for Paris had to be the paycheck. We hear she's getting $300k per gig!

Saturday nights are way more than alright for P.

Caitlyn Jenner's gotten much looser with her attitude toward booze in the weeks since saying goodbye to Bruce.

Bruce was always very health conscious, and would only drink the occasional beer -- but our sources say Caitlyn's now a connoisseur of wines and champagnes ... relaxing with a few glasses while hanging with her girlfriends.

And CJ's not just highfalutin -- we're told she did down a few shots too at The Abbey over the weekend.

Our sources say people in Caitlyn's life have noticed she is drinking more, but no one thinks it's an issue in the slightest -- she's just finally comfortable living her authentic life.

Case in point ... on Monday she was still toasting her ESPY with GFs. #YOLO

Meek Mill didn't have to make up a story for his GF Nicki Minaj about going out to the strip club ... because she was right there with him!

Meek and Nicki hit up V Live Houston on Saturday night -- and brought the rain with 'em. We're told Meek dropped around $40,000 in cash on the dancers.

Nicki gave Meek some room to operate ... hanging in her own VIP section while he and his boys paid bills for the club's most wanted -- Barbie Monroe, Karma, and Phu**ed Fame ... to name a few.
