Party All The Time

Something's definitely going on between Zayn Malik and Gigi Hadid ... they partied together Tuesday night and security did their level best to shield them from photogs.

They showed up at The Nice Guy in WeHo at around 10:30 PM where they entered from the back so there's only a fleeting glimpse. Two hours later they resurfaced and left together.

Gigi hit up the same spot Sunday night at Justin Bieber's after-party, where she was photographed leaving in a SUV with Zayn.

Anyone confused?

The Cleveland Browns say they're "disappointed" in Johnny Manziel for hitting the club scene during the team's bye week ... and have demoted him from starter to 3rd string QB.

Browns head coach Mike Pettine issued a statement saying, "Josh McCown will be the starting quarterback on Monday night against the Ravens."

"I’m especially disappointed in his actions and behavior because he has been working very hard. The improvements from last year to this year have been tremendous but he still has to consistently demonstrate that he has gained a good understanding of what it takes to be successful at the quarterback position on this level."

"Everyone in this organization wants what is best for Johnny just like we do for every player in our locker room. It goes well beyond the field. We are going to continue to support him in every way possible, but at this point, we’ve decided it’s best to go with Josh as the starter going forward.”

As we previously reported, Manziel hit up at least two clubs in Austin, TX on Thursday and Friday -- partying with bottles of champagne.

It was clearly concerning to Browns brass considering Manziel entered treatment earlier this year after a hard partying streak.

More photo evidence from Johnny Manziel's party weekend -- this time, a pic of the Cleveland Browns QB at RIO nightclub in Austin, TX on Thursday night.

Same hat. Same mustache. Same bracelets as he was wearing in the champagne video from the next night.

Sources in the club tell us Johnny was behaving himself -- not doing anything crazy.

We spoke with a staff member at the RIO who confirmed Manziel was at the bar on Thursday night.

Johnny Manziel's party weekend may have cost him his starting job ... with Browns coach Mike Pettine saying he's not ready to commit to Johnny as the #1 guy on Sunday.

Pettine just spoke to the media about the TMZ Sports footage of Manziel partying Friday night at an Austin nightclub with bottles of champagne.

Pettine says the Browns are still investigating the situation -- but admits he's disappointed in Manziel.

"I can't stand here and say it's not disappointing," Pettine said ... noting the whole thing was "frustrating."

Pettine says he'll have more information on the QB situation in Cleveland Wednesday.

Justin Bieber and Selena Gomez are back together but only as friends ... at least for now we're told.

Our sources say Justin and Selena are telling friends they haven't hooked up again despite being inseparable over the weekend.

The two were spotted out in Bev Hills Friday night, and then again Sunday at Justin's AMAs after-party at The Nice Guy in West Hollywood.

We're told Justin and Selena kept their hands to themselves mostly at JB's party, and they didn't leave together at the end of the night. Justin left with Halsey, who appears on his new LP.

Even if they're not doing the deed, it's interesting Selena's back to hanging with Justin's crowd. She'd distanced herself from them after the breakup.

The old Johnny Manziel is back ... and that's not necessarily a good thing.

TMZ Sports has obtained footage of the Cleveland Browns quarterback raging at a nightclub in Austin, TX on Friday night with a bottle of Dom in his hand ... the second night of a back-to-back bender.

It's like the LAST place you'd expect Kris and Caitlyn Jenner to hang out -- but here they are ... tossing beads together off a balcony to drunk Bourbon Street revelers.

We're told the exes were in the French Quarter shooting for an episode of "I Am Cait." They hit up a couple bars and tried their hands at the Mardi Gras bead tradition. Far as we know, both women kept their tops on though.

Jennifer Lopez and Diddy flashed back to the turn of the Millennium -- when he was Puff Daddy and she was not Jenny From the Block yet -- and partied after the AMAs as if they were still dating.

Clearly there are no hard feelings between the exes who looked like they had a blast at J Lo's after-party. They've come a long way since ending their relationship 16 years ago ... when Diddy got booked for a weapons violation after that NYC nightclub shooting.

Good to see they've put it all behind them. Jennifer's current guy, Casper Smart, was there too ... we got all 3 outside the party.

It was just a moment in time ... when Kylie Jenner was available for the first time as an adult, but alas it was not meant to be.

Whatever split them up was not enough to keep Kylie and Tyga apart. We got this video of them arriving at Justin Bieber's AMA after-party Sunday at The Nice Guy in WeHo.

As they leave, Kylie gently holds on to her man, who deftly maneuvers through a sea of photogs.

Another day will come.

Jay Z and Beyonce had some of the best seats in the house Friday night for Britney Spears' Vegas show.

The two were spotted at Planet Hollywood for the concert, and both tried to keep an extremely low profile. You can see from the video below, Bey kept her head tucked on the way out and Jay Z covered up with a hood.

Britney recently signed a brand new $35 million deal with PH ... so maybe Beyonce's just taking notes for a show of her own.

There's nothing Cameron Diaz and Nicole Richie don't do together these days -- including partying like teenagers at their husbands' concert.

The sisters-in-law fangirl'd out in the VIP section of Good Charlotte's Thursday night gig at the legendary Troubadour. While Benji and Joel Madden rocked onstage ... the ladies were rocking beside Nicole's dad Lionel Richie.

Just a couple days ago, Cameron and Nicole shopped for shrubbery together ... so, they're definitely in the BFF zone. Check out the clip, Nicole seems less into the performance than Cameron, but she's been at this longer.

Rihanna and Travis Scott are rolling into the same venue but keeping an arm's length from one another ... at least for the public.

RiRi attended Travis' Brooklyn concert Thursday night but left by herself with Travis trailing not too far behind in his own car. No surprise ... we saw them a little later arriving at Up&Down nightclub. Again, just minutes apart.

They haven't been seen out much since their heavy makeout sesh at a Fashion Week after-party ... but looks like it's still on.

Jeremih just got a late birthday present ... a sweet deal in his DUI case.

The singer pled no contest to one count of reckless driving, and the DUI charge was tossed. As part of the deal, he'll have to complete an alcohol and drug ed course. He'll be on probation for 2 years.

The singer was pulled over on his 28th birthday back in July and spent the night in jail. The incident didn't stop him from hitting the clubs ... the next night.

Fabolous took it way back to the '90s for his 38th birthday party by celebrating with his pals ... who also happened to crank out huge hits from that era.

Faith Evans, 112 and Diddy -- who, of course, teamed up in '97 for "I'll Be Missing You" -- were all on the guest list ... and Diddy even got on the mic for a hip-hop take on "Happy Birthday."

Oakland Raiders star Aldon Smith will be suspended by the NFL for an entire year -- starting Tuesday -- for his role in a DUI arrest back in August ... so says Adam Schefter.

As we previously reported, Smith was arrested on August 7th -- after cops say he tried to get out of his car in a lot about a mile from Levi's Stadium when he swung the door open into the car next to him, causing roughly $500 in damage.

Cops say Smith got back in his car and left ... only to return to the scene on foot, where cops were waiting. Aldon then bombed a sobriety test and was arrested for DUI, hit and run and vandalism.

Smith was charged with DUI and a hit and run -- and pled not guilty.

Smith was on thin ice with the NFL -- after already being suspended for 9 games back in 2014 over a DUI arrest in 2013.

Smith was cut by the 49ers after the DUI incident back in August -- and the Raiders must have known a suspension was a possibility when they signed him.

Smith was seen saying goodbye to teammates earlier today.

Ryan Seacrest wouldn't dream of backing out of his New Year's Eve gig, despite the potential threat of terrorism ... and he's hoping the expected Times Square crowd feels the same way.

In the wake of the Paris terror attacks -- you'd think the thought of possible danger would be weighing on his head, but Monday night outside Jon & Vinny's in L.A. ... Ryan seemed more determined than anything else.

We asked him if people should be afraid to go out on NYE -- knowing, of course, that more than a million people party in Times Square each year.
