Party All The Time

No one -- on Earth -- was more fired up about the Chiefs' epic comeback against the Houston Texans than Patrick Mahomes' girlfriend, Brittany Mathews ... and it's all on video.

Brittany WENT FULL-ON BERSERK while watching her boyfriend engineer one of the greatest comebacks in NFL playoff history ... screaming, yelling, talking trash!!!

The 23-year-old was watching the game from a VIP suite at Arrowhead Stadium in Kansas City ... surrounded by other Chiefs players' GFs and her BFF Jackson Mahomes, Pat's younger bro.

As the Chiefs started cutting into the Texans 24-0 lead, Matthews could barely believe it -- LOSING HER MIND while Patrick went off on the field.

"THAT'S MY BOYYYYYYYYYYYYY," she yelled from the suite ... adding, "WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!"

Once it became clear the Chiefs were taking control, Matthews sent a video message to all of her haters ...

"All those people that doubted us and hated on us, that thought we were gonna lose this game? GUESS AGAIN!!!"

Matthews ain't exactly a wallflower at Chiefs games -- she's as loud and rowdy as they come -- which might be why Patriots fans heckled the crap out of her during a regular-season matchup at Gillette Stadium toward the end of the season.

The good news for Brittany ... the Chiefs will be back at Arrowhead next weekend to take on the Tennessee Titans in the AFC Championship game.

Forget NyQuil ... Bad Bunny is apparently the perfect cure for the flu -- 'cause after he brought LeBron James onstage Sunday -- the Lakers star looked magically cured!!!

LBJ has been battling a bad cold this past week ... and he was feeling so crappy over the weekend, he missed L.A.'s game against the Thunder on Saturday.

But, on Sunday, clearly, all the guy needed was some Puerto Rican Latin trap and reggaeton to feel better ... 'cause when Bad Bunny brought him onstage at Calibash at Staples Center, LBJ raged his face off!!

Watch the video ... LeBron sure looks like he's feeling okay to us -- boppin' around and getting the crowd fired up. He even got in a little dance sesh with Bad Bunny himself!!

The Lakers play the Cavs on Monday night ... and based on Bron's performance Sunday -- we're pretty positive he'll make his return to the hardwood for the game.

Sorry, John Beilein.

Not like Joe Burrow needed any motivation ... but here's Tigers superfan Boosie Badazz telling TMZ Sports he's planning a rager for the ages if the QB brings home a title for LSU!!

Of course, Boosie is a life-long Purple and Gold backer and is a HUGE Burrow guy -- he even FaceTimed the Heisman Trophy winner back in November.

We spoke with the rapper before Burrow faces off against Trevor Lawrence and Clemson in the national championship on Monday ... and he says there's gonna be some models waiting for the guy if he comes up with the dub.

"I'm thinking about throwing Joe a party at my house," Boosie says. "Everybody got their clothes on though. Real model-type women. Joe needs the prettiest model in the game right now."

"Joe needs somebody like Scarlett Johansson. Joe a big dog. Y'all don't see it right now, but this the next Tom Brady."

As for the game, Boosie is confident Burrow can lead the Tigers to the promised land because "he has no fear in his heart ... he is the truth and I stand behind Burrow."

The Chiefs beat the Houston Texans in spectacular fashion this weekend -- but nothing was more spectacular than one of their offensive tackles busting two beers together.

As Patrick Mahomes made a touchdown pass to Blake Bell at the top of the fourth quarter in Sunday's playoff game ... the guy's teammate Eric Fisher ran over to celebrate with him and showered in the glory with brew and an homage to Stone Cold Steve Austin.

Fisher ran over to the stands and grabbed what appeared to be two waiting beer cans that were conveniently placed, and then smashed them over his head like SCSA used to.

Looks the apparent owner of the beers -- the guy with the glasses -- wasn't too upset with the move either -- if anything, Fisher was getting cheered on by all the Chiefs fans.

Will Smith could still get jiggy with it ... because he's not completely shutting down the idea of putting out another album.

We got Will in New York City Friday, and our guy asked if he's ever going to drop a follow-up record to 1997's "Big Willie Style" ... and Will leaves the door wide open.

The 'Fresh Prince' is in the Big Apple promoting his latest movie with Martin Lawrence, "Bad Boys For Life" ... and it sounds like Will's still got a soft spot for the recording studio.

Will's obviously not averse to sequels ... so it's not a stretch to think he'll make his return to the rap game one day. Our photog has a special date in mind for a potential album drop.

Billie Eilish is ripping a page out of Mark Wahlberg's playbook ... by living it up in Hawaii.

The Grammy-nominated singer's in the Aloha State having a blast with her friends. In a rare wardrobe move ... Billie rocks the hell out of a bathing suit. We're so used to seeing her in baggy clothing ... but when in Rome, right?

Looks like a few friends joined her on the trip and they went on quite the excursion ... from zip lining and kayaking to going on a sick helicopter ride and swinging into a lake. She also shared what looks like a Jacuzzi with a friend ... never mind the rain.

And, even though the weather hasn't been cooperating ... Billie still managed to have an incredible photo of her looking outside a helicopter window with a perfect rainbow as her backdrop.

Billie, of course, has been nominated for 6 Grammys ... including Album of the Year, Record of the Year, Song of the Year and Best New Artist. "Ocean Eyes" was arguably the song that put her on the map but "Bad Guy" is what's now earned her critical acclaim.

PARTY TIME IN THE BAYOU!!!!

LSU just announced it's canceling ALL of its classes on both Monday AND Tuesday so students can rage their faces off for the National Championship Game against Clemson!!

The Tigers are set to play the Tigers on Monday ... and in anticipation of none of the students showing up for class anyway, the Louisiana university made the call Friday.

Seems like a pretty smart move by the school ... the game is being played just a short drive away from the Baton Rouge campus in New Orleans at the Superdome.

As for Clemson ... no announcement has been made about its classes yet -- so keep your fingers crossed for those kids!!

By the way, the game should be awesome ... both LSU QB Joe Burrow and Clemson QB Trevor Lawrence are expected to be the next two No. 1 overall picks in the NFL draft.

Plus, there are about two dozen other players on the field who could eventually end up being NFL stars down the road!!

Did you know Todd Gurley could party like a frat star!??!

Neither did we ... until Wednesday night -- when the L.A. Rams running back chugged beers and bro'd down with Dodgers stars at the L.A. Kings game!!!

The video of Gurley throughout the night was more entertaining than the actual on-ice action ... 'cause the 25-year-old lived it up in on-the-glass seats for the Kings-Stars game at Staples Center.

Ya gotta watch the clip ... Gurley rages his face off, throws back some suds and even gets into a chug-off with Dodgers players Gavin Lux, Matt Beaty and Kody Hoese.

IT WAS AWESOME!!!

But the best part? Arena cameras broadcast almost all of it on the jumbotron!!!!

Of course, Gurley and the Dodgers could use the booze ... both squads had rough seasons, with the Rams missing the playoffs and the Dodgers exiting the postseason early.

As for if their antics helped the Kings ... not really, 'cause L.A. lost to Dallas 2-1.

Here's Elon Musk getting super loose on the floor -- not at a nightclub, but for the opening of his new factory in China -- and his moves scream ... let's sell some Model 3s, baby!!!

The Tesla honcho was in Shanghai Tuesday celebrating the launch of Tesla's manufacturing plant, and he was apparently so amped he just couldn't resist busting out his best dance.

Ya gotta see Elon's bag of tricks ... he slips off his jacket and tosses it aside before doing the ol' walk like an Egyptian (s/o to The Bangles). Ya might've seen some of his other moves ... in a retirement home.

Still, the crowd ate it up -- clapping, cheering and encouraging him to keep it moving ... keep his body moving.

Brad Pitt and Jennifer Aniston are forever linked ... and they only add strength to that bond when they hit up the same parties after awards shows.

The 2 stars both attended the CAA after-party at the Sunset Tower Hotel Sunday night, following the 77th Golden Globe Awards at the Beverly Hilton ... where they also sat in close proximity.

Of course, both Brad and Jen were nominated for awards -- he for Best Supporting Actor in "Once Upon a Time in Hollywood" and she for Best Actress in "The Morning Show" -- so they had good reason to keep the party going at the talent agency bash.

Still, they're going to turn heads when they're rubbing elbows at an event ... even if they arrive and leave separately, as they did at the CAA after-party.

Tiffany Haddish warned the crowd a couple of times and then greatness ensued when she started rapping!!!

Tiffany had one helluva busy Sunday night ... which ended in spectacular fashion at Netflix's Golden Globes after-party in Bev Hills. Tiffany muscled her way over to the DJ's booth, grabbed the mic and hyped the crowd up before rapping to City Girls' banger, "Act Up."

Ya gotta see the crowd under a massive tent on a lot adjacent to the Beverly Hilton Hotel. They went nuts!!!

It was a pretty eventful night for Tiffany. The comedian, who wore an elegant pink dress, displayed a Star of David necklace honoring her Black Jewish roots on her father's side, which she discovered after taking a genealogy test.

As the Golden Globes broadcast wound down, the after-parties fired up -- and it was truly a who's-who of Hollywood ... 'cause everyone and their mothers came through.

Some of the biggest studios in showbiz threw their own respective shindigs, including Hulu, Amazon, HBO, Netflix, Warner Bros. and others. That was more than enough to get mostly everyone who'd just been at the Beverly Hilton to come out for another hurrah.

Folks like Brad Pitt, Robert De Niro, Isla Fisher, Naomi Watts, Tiffany Haddish, Awkwafina, Kate Beckinsale, Patrick Stewart, Paris Hilton, Joaquin Phoenix, La La Anthony, Keegan-Michael Key, Helen Mirren, ScarJo and Al Pacino were in attendance.

Other stars seemed to be down to pose as duos, like Sofia Vergara and Sarah Hyland; Salma Hayek and Patricia Arquette; Nicholas Braun and Robert Greenblatt; Sabrina Carpenter and Joey King; Lisa Bonet and Zoey Kravits; Jason Momoa and Sacha Baron Cohen ... and lots more.

All Mariah Carey wanted for 2020 was a massive place to celebrate a big year and ring in the new one ... and she got exactly that with a palace in the Dominican Republic.

Mimi spent just a little over a week in the Juanillo Estates in the luxury community of Cap Cana. She was there with her BF, Bryan Tanaka, and her 8-year-old twin kids, Moroccan and Monroe.

The estate's fit for an R&B queen -- 40,000-square-feet of interior space, its own private white-sand beach, 9 bedrooms, a 24-seat grand dining table, an expansive wraparound pool, and, not one, but TWO fully-equipped kitchens. Oh yeah, the pad's also fully staffed. #Baller.

MC celebrated two huge 2019 milestones -- her Christmas classic, "All I Want for Christmas Is You," made her the first artist to ever hit No. 1 on the Billboard Hot 100 chart in four separate decades. She also released a new music video for the track ... which has already eclipsed 32-million views.

And, to ring in the New Year ... Mariah and the fam enjoyed a quarter-million-dollar fireworks show. Now that's getting lit.

Anyone looking to rent out Mariah's spot better get ready to shell out a pretty penny ... it costs around $18k per night to stay at the $30 million estate.

Saint Laurent got into the act for Golden Globe weekend, throwing an epic party ahead of the ceremony.

It went down at a home in the Los Feliz area of L.A., and tons of stars were more than happy to accept the invite. Among them ... Dwyane Wade, Gabby Union, Hailey Bieber, Kaia Gerber, Kate Bosworth, Rami Malek and Taron Egerton.

The bash was thrown by Rami Malek and Anthony Vaccarello. Rami's nominated for Best Performance by an Actor in a TV series for Mr. Robot. It's the third time he's been nominated for the role, but he's come up goose eggs each time.

Hollywood's finest came out in droves for a pre-Golden Globes event which saw them mingling with Olympians -- and the get-together was nothing short of a tearjerker.

The ritzy shindig went down Saturday afternoon at one of the first-ever homes established in Bev Hills ... the Virginia Robinson Gardens mansion. It's called Gold Meets Golden, and the whole idea is to pair celebs with pro athletes all in the name of charity --  this in anticipation of Sunday's award show and the 2020 Tokyo Olympics, of course.

For this 7th year -- which was hosted/presented by Coca Cola, BMW Beverly Hills, FASHWIRE along with other sponsors -- the proceeds were going toward Angel City Sports ... an org promoting adaptive sports for kids, adults and vets with physical disabilities.

Definitely a cause worth getting behind ... and you could tell as much by who showed up -- including Nicole Kidman, Chris Evans, Rami Malek, Taron Egerton, Cynthia Erivo, Matt Bomer, Ben Platt, Beanie Feldstein, Zoey Deutch, Joey King, Naomi Watts, Lou Ferringo and more.

Of the Olympians and athletes in attendance ... Jackie Joyner Kersee, Nadia Comaneci, Bart Connors, Ibtihaj Muhammad, Ian Thorpe, Willie Gault, Metta World Peace, Apollo Anton Ohno, Kristi Yamaguchi and several others.

Check out the clip above ... you see Cynthia belting out a rendition of John Lennon's "Imagine," Taron and Sistine Stallone putting medals on the 2014 bobsled team and Matt Bomer presenting a cake to diver Greg Louganis for his 60th bday this month.

LA Galaxy star Jonathan dos Santos is havin' one helluva start to his 2020 ... hitting up the beaches in Mexico with not only one gorgeous bikini-clad lady -- but TWO gorgeous bikini-clad ladies!!!

The 29-year-old MLS midfielder is enjoying his time away from the soccer field this week by catching some rays in Cancun ... and the views are spectacular.

Oh yeah, and the beach is pretty cool lookin', too.

JDS has been playing in LA for 3 years now ... and has recently said he wants to retire a member of the Galaxy when it's all said and done. We take it his retirement plan involves more beaches and babes.

In total, there were more than 2 hotties with dos Santos in the water ... but that headline wouldn't have been as creative, now would it have???
