Having just returned from a ski trip to Big Bear just outside of LA, Selena Gomez and friends went to pick up some take-out for dinner after the group returned home.

Selena's actually been back in LA for at least a week following release from a treatment center where she was seeking help for mental health issues. She's been lying low and staying off social media ... until Tuesday, when her friends posted pix of the friends' trip to the mountains.

Meanwhile, her ex Justin Bieber's been exhibiting some strange behavior as of late ... we caught the emotional pop star shaking and bobbing his head back and forth repeatedly in his car yesterday as he was pulled over on the side of the road. It's certainly not the first time we've noticed Justin with this nervous twitch -- something that seems to go beyond a nervous twitch, actually. We're actually worried for him!

After stopping for coffee before an afternoon workout Wednesday, Bieber headed to Compton -- not sure why.

Then Wednesday night he hit up Hillsong's weekly evening service ... without wife Hailey Baldwin. We're pretty sure she's in town but busy working so Biebs hit up the religious revival solo. What if Selena had been there?!!!

Time to reach for that Proactiv!

We caught Justin Bieber grabbing coffee this morning while chatting on his cell phone, and we hate to be mean, but the singer really needs to take care of his skin!

We know stress causes breakouts, and he's had more than his fair share of that in the past few months, but still... dude needs a facial to help with this acne!

From what we're hearing, JB has been overwhelmed with trying to be a perfect husband to wife Hailey Baldwin, while also feeling the pressure to make new music. Oh, and there's Selena Gomez's mental breakdown, which took it's toll.

A source tells X17:

"Justin has had a lot on his plate lately. He's trying to do right by Hailey and make sure she's happy in their marriage, and he's also trying to figure out how to keep his team happy and make new music. It's a lot. Being a celebrity stresses him out, and he wishes he was just a normal guy. He's sick of being followed by cameras and asked about ex Selena Gomez every time he leaves his house. He wants to move forward in life."

Is HE headed for a breakdown of his own? Watch the below video, he's just parked on the side of the street rocking back and forth like he's trying to ward off a panic attack!

We're shocked Angie allowed this!

Brad Pitt spent his 55th birthday hanging out with his kids at home, People reports.

The mag claims "several" of his children slept over on Monday night, but they don't specify which ones. Rumor has it the actor's relationship with eldest son Maddox is all but over, so something tells us he skipped out on the celebrations.

"The kids arrived at Brad's house on Monday afternoon for a sleepover. Some of them were picked up at 12:30 p.m. on Brad's birthday—Tuesday—and taken back to Angelina's. Some of them stayed for more time with their dad," another insider dished to E! News.

"It was a huge deal for Brad and something he has wanted for a long time. It was the first time they had spent the night and meant the world to him. It was a great birthday present and he's looking forward to spending holiday time with them in the coming days," the source added.

As for the ongoing custody battle between the exes?

"There's an arrangement in place but it's not a permanent agreement, and there's a long road ahead. All Brad cares about is the kids, they're his number one priority and he's focusing on them," the source revealed.

It seems Papa Pitt is back in his family's good graces!

She's not afraid to spoil them!

Kris Jenner took grandson Mason on a shopping spree for his ninth birthday, and she ended up plunking down more than $3K for this Baroque Print Padded Coat by Versace. He clearly inherited Kourtney and Scott's taste for the finer things in life, including fashion!

The momager might want to be slightly more careful with her spending, considering Keeping Up with the Kardashians ratings are at an all-time low! The Season 15 finale on E! saw a 37 percent drop from the number of viewers for its season premiere. Yikes!

They better come up with some juicy plot lines to gain back viewers! They could let Kimye's marriage drama play out, and Kylie and Travis Scott could have a televised wedding. Of course, Khloe could also get pregnant again with cheater Tristan Thompson, and Kourtney and Scott could reconcile. Make us a producer!

We asked the K clan matriarch about the ratings crisis, and whether she blames son-in-law Kanye and his tweets for the sharp decline in their popularity. Watch what she says!

Responding to what appeared to be a call for help from comedian Pete Davidson, @DanCrenshawTX with me for #HouNewsmakers EXTRA talks about his response and phone call. https://t.co/BRiFwhBjD8 pic.twitter.com/GpqlUCPXpw

This is an unlikely bond being forged.

Congressman-elect Dan Crenshaw and Pete Davidson didn't get off on the best foot, after the comedian poked fun at the former Navy SEAL's eyepatch in an SNL skit, but they've moved past that, and Crenshaw reached out to the troubled star after he posted suicidal messages on Twitter.

"It was pretty devastating. You don’t want to see someone in that position to the point where they’re putting out a cry for help on social media. That’s not a good place to be in," ” Crenshaw, 34, said on KPRC2 Houston.

Crenshaw then shared what the two discussed during their conversation.

"We don’t go back very far, we’re not good friends, but I think he appreciated hearing from me. What I told him was this: Everybody has a purpose in this world. God put you here for a reason, but it’s your job to find that purpose. You should live that way … seeking out that purpose, not expecting it to be given to you by anybody else. Know that you have value and do more good than you realize for people," he revealed.

TMZ reports that Davidson has "reached out" then "lashed out" multiples times in recent weeks, and truly believes that his friends and coworkers "couldn't care if he lived or died." Those around him have been extremely supportive, but he still feels as if "the world is against him." This is mental illness, folks!

This just goes to show support comes from unlikely places sometimes!

She's back!

Selena Gomez has completed treatment at the mental health facility where she's been since her September breakdown, and the first thing she did is head to Big Bear for a snowy vacation with her close pals.

The singer smiled for the cameras in snapshots posted by friends Connar Franklin and Bailee Madison, and it's nice to see her enjoying life after a rough couple of months.

The "Come & Get It" songstress is said to be in a much better mindset, too.

"Selena is definitely in a healthier place than she was a few months ago. It took lots of energy, focus and therapy to get over that particular hump in her life," a source dished to Us Weekly.

The brunette beauty was hospitalized twice in September shortly after Justin Bieber's secret courthouse marriage to Hailey Baldwin, and she's been battling health issues stemming from her lupus.

"[Selena] is feeling much better and looking forward to getting back to normalcy," another insider told People.

We admire her strength!

We didn't know it was THIS serious!

In private emails that have now been introduced as evidence, Kylie Jenner and Khloe Kardashian conspire to get Rob & Chyna canceled for a second season, and they use their own show Keeping Up with the Kardashians as leverage.

The former stripper is suing her ex and his famous family for torpedoing her reality star career and thus causing her lost wages, and it seems there's some truth to her claims.

"I feel very strongly about canceling Season 2 for Rob&Chyna. The only reason Chyna wants to be with my brother is for this show. She does not love Rob and their relationship is too fake and destructive," Kylie wrote to Khloe and two redacted names.

"We all know filming isn’t my favorite but I will sacrifice and promise you guys episodes and stories and I’m sure all my sisters will be on board to make up for all the episodes Rob&Chyna were supposed to bring in. The public has been exposed to what a fake relationship they have and it’s embarrassing and makes us all look fake. The show is giving this toxic woman money and exposure she lives and breathes for and by continuing it. She will proceed with using and physically abusing my brother. … Her association is detrimental to our family and Keeping Up W the Kardashians," she added.

That's when the Revenge Body star issued an ultimatum.

"The sisters are clearly concerned and uncomfortable for our brothers safety and the credibility of the brand at this point due to how they [Rob and Chyna] are both tarnishing it. … We are even considering not moving forward with our show if theirs continues. That’s how strongly we feel this is damaging to our family," she wrote.

BC will have her day in court, as Los Angeles Superior Court Judge Randolph M. Hammock ruled on Monday that the case will go to court in February 2020.

"Chyna is extremely happy that she will have her day in court. This has been very hard fought and we are very grateful that the judge sees the validity of our point. Chyna will have her chance to testify in front of a jury of her peers and have her side of the story told in court," Chyna's attorney Lynne M. Ciani told Radar.

Chyna is like a fly that just won't go away!

We're glad people are being proactive about this.

SNL boss Lorne Michaels has decided to pull Pete Davidson from the show temporarily so that he can seek treatment for his suicidal thoughts, Page Six reports.

"The decision was taken to give Pete a break on Saturday night – his sketches were dropped before the early evening rehearsals. Lorne has pledged to help all he can, including sending Pete to get help. Everyone on the cast is hugely protective of him and were obviously upset — particularly Colin Jost and Michael Che on ‘Weekend Update,’” a source told the outlet.

It's believed that the comedian will return to the show after the new year, hopefully in a better frame of mind.

His ex Ariana Grande is trying to stay strong amid all his troubles, but the attention it's getting has become overwhelming for her.

"She is at wit’s end with all of this and is so emotional right now. She hasn’t gone on social media and is trying to just do her best and not think about it. Everywhere she goes people are asking her, ‘How is Pete? Have you talked to Pete?’ It is just really unfair to her because the two of them ended their relationship," another insider told Radar.

"They both decided it was for the best, and now he is pulling up all this trying to get her to save him. She can’t save him — only he can save himself at this point," the source added.

We hope this doesn't have a tragic ending.
