Party All The Time

Bella Hadid and The Weeknd shook off break-up rumors by partying on a yacht Monday in Miami with pal Karrueche Tran.

As TMZ first reported, Bella and Weeknd are still going strong ... especially since Weeknd is on break from his tour.

We're told they're spending New Year's Eve together and Bella will be front and center when Weeknd plays his January 2 show in Vegas.

LeBron James has joined Odell Beckham Jr. and James Harden in the seemingly never ending pro-athlete dance recital ... and he brought his whole team with him.

LBJ hit up INTL nightclub in Scottsdale, AZ Sunday night with Kyrie Irving, J.R. Smith and Iman Shumpert and the guys showed off the latest dance craze "Hit Them Folks" for the partygoers.

We're told the festivities lasted until about 1 AM ... and get this ... our spies say not one drop of alcohol was consumed by the ballers.

The Cavs play the Suns in Phoenix Monday night ... better get a win to go with all that cuttin' a rug.

The Weeknd drenched a crowd at LIV nightclub in Miami with Ace of Spades champagne -- which runs in the vicinity of 1,700 bucks.

He's got more than one reason to celebrate ... hit album, 7 Grammy nominations and a hot supermodel girlfriend, Bella Hadid.

Some guys have all the luck.

Mack Wilds -- the "90210" dude who plays Adele's ex in the "Hello" video -- shut down traffic near Times Square after popping Belair bottles in the street.

Wilds and some friends, including NYC celebrity jeweler Mr. Flawless, chose a congested spot for the impromptu photo shoot ... the middle of 47th Street and 6th Ave.

Mack has something to celebrate. The song has gone 4 times platinum. The album is positioned to sell another million copies for the third week.

Even megastars like Russell Westbrook have bouncer drama at Hollywood nightclubs -- 'cause the NBA superstar got stopped at one of the hottest bars in L.A. Monday night 'cause the bouncer didn't know who he was.

The Oklahoma City Thunder superstar hit up The Nice Guy -- often frequented by huge stars like Justin Bieber, Gigi Hadid and Leonardo DiCaprio -- when the bouncer pumped the brakes at the door.

Raven-Symone couldn't get the real Kim Kardashian and Kanye West to celebrate with her for her big 30th birthday, so she opted for the next best thing.

Justin Bieber got comped big time for a bar tab at an Atlanta club and left behind a tip that has our newsroom deeply divided.

Justin and his entourage were in the ATL last week for Jingle Ball. After the performance the party moved to Tongue & Groove nightclub, where Justin ordered up a storm in bottle service.

- 2 bottles of Don Julio 1942 ... $500 each
- 1 bottle of Grey Goose ... $300
- 1 bottle of Jack Daniels ... $275
- Some beers ... $25

The table total was around $1,600, which the club comped. The Biebs left his 2 waitresses $200 each. We're told Justin was amazing with interacting with the staff and club guests, and even entertained the packed crowd by taking photos with them.

So we gotta ask....

Aubrey O'Day and PaulyD have defied the odds and are in what appears to be a real relationship, cemented by alcohol.

It seemed ridiculous when they hooked up on a reality show a month ago. It seemed like a momentary fling, but a month later she's travelling to his DJ gigs.

Pauly hosted Pool After Dark in Atlantic City over the weekend, and Aubrey was front and center.

11:01 AM PT: Sources tell TMZ ... Scott showed up for a few hours but was NOT drinking while he was at the club.

Chris Brown had a hugely successful listening party for his new album "Royalty" ... and Scott Disick was right in the middle of it.

A slew of people were front and center at Hyde on the Sunset Strip ... Usher, French Montana, Kendall Jenner, Andre Berto, Big Boy and lots of others.

Scott's presence was a little weird ... it was turnt up for sure, and Scott just got out of rehab.

BTW, "Royalty" drops December 18.

Justin Bieber may be juggling sisters, because he partied Tuesday night with Kendall Jenner at the same night club where he hooked up with Kourtney Kardashian over the weekend.

Justin and Kendall arrived separately at The Nice Guy in WeHo at around the same time -- 10 PM.

They left separately, too ... just like Friday night when Justin and Kourtney left Justin's go-to club and headed for his Bev Hills hotel, where she stayed 'till 4 AM.

Beyonce got all ho ho ho for her NYC office Christmas party. Bey was glowing as she left in full regalia.

Nothing says a Jewish boy's becoming a man like a Fetty Wap performance at his Bar Mitzvah, and a wad full of benjis.

The owners of Baron Tequila, a Kosher tequila brand, paid Fetty $50k to rock the house at Illagio in Queens for their son, David. Fetty, who showed up on crutches -- still recovering from his motorcycle wreck -- rocked the house and gave $1,000 in hundred dollar bills to David so he could "make it rain."

This is Fetty's 2nd successful collabo with the tribe ... he and Lil Dicky made a hilarious video called "$ave Dat Money" which has already racked up more than 20 million views.

As for how dope this party was -- there were arcade games, a mechanical bull, and sushi made of candy wrapped in fruit roll-ups!

Check out the video where this 13-year-old boy (now a man) sported a hat bigger than his head in honor of Fetty.

Is there a yarmulke in Fetty's future?

Sick moment for the St. Louis Rams Sunday -- 'cause after they beat the Lions, JAY Z met the team in the locker room to celebrate.

Sooo why?

For one, Todd Gurley is repped by Roc Nation Sports ... and also, who's gonna turn away Jay Z?

But the best moment -- as the team was bringing it in for the post-game huddle, they called over Jay to lead the chant.

Ronda Rousey's the belle of the Marine Corps Ball -- arriving to the big bash in South Carolina moments ago ... to keep her promise to Lance Corporal Jarrod Haschert.

Ronda flew out early Friday morning -- and to be honest, still seemed pretty down in the dumps nearly one month after losing to Holly Holm.

But she was all smiles at the ball -- posing for pics with the marines and their dates -- and hopefully, enjoying herself.

Ronda's gonna need to get her mojo back if she's gonna have a chance to beat Holm in the rematch -- and who better to help reclaim her swagger than a buncha devil dogs, right?!?

Oorah!

Justin Bieber made a surprise appearance Wednesday night and brought the house down at Miami hotspot, LIV Nightclub.

He spent most of the night up onstage, dancing and singing to his songs -- and you gotta see the highlight of the night. Full light show, screaming fans, and confetti cannons for "Sorry."

Bieber's on fire right now -- dude's got 3 songs in the top 7. Fans love him and he loves 'em back ... but PLEASE "don't touch" the Yeezys, folks.

Andrea Bocelli is still giving free performances in between his huge arena shows.

Bocelli surprised 150 employees at Skybridge Capital, a hedge fund in NYC, when he popped up at their holiday party and belted out "Ave Maria." No big deal.

The singer's in town for a Wednesday night gig at Madison Square Garden, but the Skybridge crew got a MUCH more intimate show inside the Hunt & Fish Club ... a fancy steak house in Midtown.

Bocelli only did the one song, but if ever there was a case for dropping the mic ... this is it.

We're told he hung out for an hour to take pics and chat. Molto bene!
