NHL superstar Connor McDavid is FINALLY legally allowed to drink in America ... and he celebrated by blowing it out at a Vegas nightclub -- with the guys from The Chainsmokers.

The Edmonton Oilers captain hit up XS Nightclub in the Encore hours after beating the Vegas Golden Knights in an overtime thriller ... and got the V.I.P. treatment with a massive welcoming party.

FINALLY LEGAL

The better news for McDavid ... the Oilers don't play again until Saturday -- so he's got an entire week to celebrate (and recover) before going back to work.

Congrats!

Elon Musk & Amber Heard Dance Party at The Abbey!!!

A SECRET DANCE
TMZ.com

Elon Musk and Amber Heard have made another big move in their relationship ... on the dance floor!

The possibly-on-again couple arrived together at The Abbey in West Hollywood Saturday around 1 AM. We're told they had some drinks and danced with a few friends.

It looks like they really enjoyed grooving to Cardi B's "Bodak Yellow."

You may recall ... we last saw Elon and Amber smooching after a lunch date in L.A. a few days before Christmas. We thought it meant they were back together, but a source close to Elon told us they weren't.

So ... how 'bout now?

Scott Disick & Tyga Kardashian/Jenner Rejects Party it Up

BOY'S NIGHT
TMZ.com

No, Scott Disick and Tyga didn't hold a "Klan Reject" meeting Thursday night ... just another day in the life of 2 apparently very eligible bachelors.

Kourtney and Kylie's exes partied together at 1 OAK on the Sunset strip and were seen hanging around waiting for their wheels. There were some baddies hanging around, but no sign of Sofia. Scott jumped in his raised Mercedes Benz G-Wagon and Tyga followed shortly after in his Bugatti.

Life in the fast lane ... soooooo not Kourtney and Kylie's jam anymore.

Usain Bolt Dances His Ass Off ... with Steve Aoki

QUICK BEATS

Usain Bolt definitely knows how to get a party going ... so it's only fitting Steve Aoki enlisted the fastest man alive to get the crowd LIT at his Vegas show Wednesday night!!

Aoki brought the Jamaican track superstar behind his booth to showcase his killer moves ... and you can tell Bolt's dancing hasn't lost a step in retirement.

FYI -- Bolt's dabbled in the DJ industry in the past, and has expressed interest in pursuing a career on the 1s and 2s ... so it's very possible he was getting some solid pointers from Aoki as well.

Collab coming soon?

SWITCHING THINGS UP

If you didn't already love N.E.R.D. and Rihanna's song, "Lemon" ... Serena Williams will change your mind in the next minute and 30 seconds.

The tennis superstar turned a Palm Beach International airport runway into her own private dance party for a photo shoot with Vogue ... and we're so, so happy she did.

Not only does the new mommy show she can still twerk like no other, she even serves up some lemons at (probably) over 100 miles per hour.

Just goes to show Serena is BACK ... but it's not like she ever left.

How did Nick Saban celebrate his 6th National Championship? PARTY IN THE BAMA LOCKER ROOM!

The man who launched the legend of Tua Tagovailoa rallied up his team in following the 26-23 victory over Georgia on Monday and led a spirited rendition of the Bama fight song.

It's a pretty awesome sight ... even if Saban's been through it before.

For some reason, Terrell Owens was with the team and soaked up the awesome moments. See -- he finally knows what it's like to be in a winning locker room!

Congrats!

Drake & Zoe Kravitz Get Cozy & Jam Out At Golden Globes Party

Drake and Zoë Kravitz partied like it's 2013, getting all handsy and rekindling an old flame ... or so it seems.

OVO and Zoë were together at Netflix's Golden Globes party Sunday night, and it wasn't hard to tell they have some history. They had their arms around each other at one point. When they weren't chatting ... Drake was doing his thing behind the turntables as Zoë danced along to Wizkid's "Show You The Money."

Drake and Zoë were rumored to be an item back in 2013 and you'll recall she posted this pic in 2014 wishing him happy birthday. Zoë told Andy Cohen last year she used to hang out with Drake, and we all know what that means.

We're told they remain longtime friends, but where there's smoke ...

Saints' Sean Payton Lights Up Locker Room Dance Sesh ... After Beating Panthers

JUICED UP!

Here's Saints coach Sean Payton dancing like his life depended on it ... after his team's huge playoff win over the Panthers!

Saints star RB Alvin Kamara shot video of the team's locker room celebration ... where the coach decided to join the party -- and let loose to Yo Gotti's hit track, "Juice."

As for the dance itself -- it was pretty damn goofy -- but Kamara and the rest of the guys approved.

Ain’t the first time we’ve seen Payton bust a move -- remember that video we got of him bumpin' and gridin' with a hot blonde in the Bahamas??

Coachella 2018 Still No-Go on Weed Even Though Cali Says Yes

Coachella 2018 falls on 4/20, but those hoping to score and smoke weed openly in Indio are outta luck, despite California legalizing it.

The city of Indio, where Coachella takes place, is cracking down on marijuana use. The city isn't allowing the selling, cultivating or distributing of cannabis. Under the new law, each town can decide whether to allow recreational weed sales, and -- sorry to harsh your Queen Bey buzz -- Indio's decided it's a no.

Coachella isn't allowing marijuana or marijuana products on the festival site either.

The city of Indio still has to abide by state law which now allows you to possess a small amount of bud for personal use, but you can't smoke it out in the open.

One glimmer of hope -- neighboring cities like Palm Springs, Cathedral City and Desert Hot Springs are all weed-friendly, so if you're over 21 you can hit up a licensed dispensary there.

Pregame!

Paris Hilton Palms Casino Loves You ... Take a Piece of Our Sign!!!

Paris Hilton and the Palms Casino in Vegas have a very special relationship ... so it's fitting they're both looking forward to a big 2018.

The Palms put up a congratulatory shout-out to Paris on their marquee this week in honor of her recent engagement to Chris Zylka ... and also plans to gift her a piece of its iconic sign when it gets replaced later this year, as part of a $485 mil property renovation.

So, why all the love? Well, Hilton's been with the hotel and casino since day 1 -- she opened it in 2001 while wearing a million-dollar dress made of casino chips.

We're told because Paris is part of Palms' history ... Palms wanted part of its history to be with her. Oh, and it says if she needs a place to celebrate her bachelorette party ... "our door is always open for you."

Golden Globes nominees James Franco, Tracee Ellis Ross, Kyle MacLachlan aren't waiting around 'til Sunday's award show to start partying.

W Magazine held their Golden Globes pre-party at Chateau Marmont Thursday night and it brought out some big celebs.

Justin Hartley, whose show "This Is Us" is nominated for a Best Television Drama Series, showed up with his new wife. Kate Beckinsale, Salma Hayek, Jim Belushi, Cody Simpson, Selma Blair, Candace Cameron Bure and Mena Suvari were there too.

Gotta hand it to the East Coasters Tommy Hilfiger and Patriots owner Robert Kraft for making it out of town during the bomb cyclone. Must've been a helluva party.

Todd Gurley Hits L.A. Hotspot 2 Days Before Playoff Game

THURSDAY NIGHT TURN UP
TMZSports.com

Todd Gurley had a big Thursday night -- hitting up the Clippers game and then Delilah (popular L.A. hotspot) ... just 2 days before the Rams take the field against the Falcons in the NFL playoffs.

TMZ Sports was at Delilah (a swanky restaurant and lounge) when we saw Gurley cruising in around 11:30 PM. He's such a big star in L.A., all he had to do was nod at the bouncer to get inside.

No word on when he left or if he even had a sip of alcohol (guessing he didn't) ... he may have just been stopping by to say hi to a friend.

Of course, the Rams play ATL in the Wild Card Round on Saturday -- and if Gurley, who's on fire right now, runs over the Falcons, no one will care about his night habits.

If they lose, however ...

Ricky Williams Come Smoke a Super Bowl With Me!! ... Hosting SBLII Pot Party

Wanna get a seat higher than the nosebleeds for the Super Bowl?? Now's your chance ... 'cause Ricky Williams is hosting his very own weed party for the big game!!

The ex-NFL superstar-turned-ganja advocate is hosting the highly anticipated event in February ... and instead of making it a BYOB party, Ricky's inviting guests to BYOW -- Bring Your Own Weed!!

The exact location of the party is still TBA ... but it'll be going down somewhere in the Hollywood Hills.

It's sure to be a great time ... after all, Ricky's the high guy!!

Odell Beckham Hits L.A. Nightclub ... In Shorts

Don't try this at home, kids ... you won't get in the club.

But dress codes don't seem to matter for Odell Beckham -- who rocked shorts to one of the hottest nightspots in Hollywood on Thursday ... and still got the V.I.P. treatment.

The NY Giants superstar hit up Warwick in West Hollywood -- sporting shorts and a sweatshirt ... and witnesses tell us he slipped in the backdoor of the place.

Inside the club, the place was packed with big sports stars -- including Von Miller and OKC Thunder players.

Bet they were wearing pants, though ...

Neymar Thong'd Out Party Yacht ... Models & Ballers!

It's good to be Neymar ...

The 25-year-old soccer superstar spent his Tuesday floating off the coast of Brazil with his smokin' hot girlfriend ... and some of his PSG teammates, who also have model GFs.

See the butt in the main image? That's Victoria's Secret model Izabel Goulart -- who's dating Neymar's Paris Saint-Germain teammate, Kevin Trapp. Kev was there, too.

But the big story is Bruna Marquezine ... Neymar's on-again, off-again lady friend who's been fully BACK ON with the soccer superstar going into 2018.

Happy new year.

Hailey Baldwin Here's to 2018 ... Bottoms Up!!!

We've figured out Hailey Baldwin's New Year's resolution -- don't change a damn thing, at least when it comes to her bikini game.

Hailey spent Jan. 1 lounging poolside in Miami -- matching hair color with her swimwear -- and perhaps nursing a hangover. As we reported, she partied on NYE at LIV Nightclub where Travis Scott performed.

The model's been getting cozy with new BF, Shawn Mendes, recently. We're not sure what Shawn had going on Monday, but looks like he made the wrong choice.

Speaking of the new couple ... Hailey was rocking what looks like a couple of diamond bands on her left ring finger, y'know ... THAT finger.

Sources connected to Hailey deny it's an engagement ring. Apparently, Shawn doesn't work THAT quickly.
