What's going on?!

Kendall Jenner's Instagram account mysteriously vanished on Sunday with no explanation, and her millions of fans are more than a little confused. "Sorry, this page isn’t available. The link you followed may be broken, or the page may have been removed," the generic error message read.

It's possible the model wanted to go on a digital detox, even though her Facebook and Twitter are still active, but it's also likely that she violated terms of use. She's been vocal about skirting around the app's nipple policy, and she could have been taken down for copyright infringement. After all, she's constantly posting pics from photoshoots and other events, and we doubt she's clearing it with all the photographers who own the images.

“I definitely have close friends, and even some family members, who are so connected to their phone and can’t get off of it. I was just zoning out, taking it all in. And Kylie wouldn’t put her phone down. I’m like, ‘That’s so crazy to me that you’re not experiencing this.’ That was the moment it kind of clicked for me. And I didn’t like it. So sometimes I delete Instagram or Twitter or Snapchat off my phone for a couple days," she recently confessed to Allure about needing time-outs from social media.

Maybe Kim's Paris robbery made her rethink documenting her every move on the Internet? Either way, we give this a few days before she's back up and running.

Scott Disick and Kourtney Kardashian traveled south of the border to Cabo San Lucas, Mexico over the weekend, and a source tells People that the duo are definitely back on.

“Scott set it all up and [it] was a way to try and make things work again with Kourtney,” a source told the mag. “He surprised her and whisked her away on this trip. They seem very close and happy."

Scott shared a sexy snapshot of his baby mama's booty in the pool on Sunday and simply captioned the pic, "Views." She shared the same shot with the same caption, though his was cropped in a bit more on her butt. Glad they're able to focus on the important stuff!

Though the two have been pretty on and off since splitting in 2015, Kourt dished to Cosmopolitan earlier this year that she wasn't sure where things stood with her sexy but troubled baby daddy. “The idea of having my family together is amazing, but it’s not the way things ended up," she said. "They may end up there. I’m not sure. To me, it’s in God’s hands. If it’s meant to be, then things will line up. We definitely tried for a long time. But relationships are exhausting! Being able to focus on the kids and me right now is good. We say to each other all the time, ‘I’m the coolest ex-girlfriend/baby mama you could ever ask for!'”

Aww, PMK has a heart after all!

On Saturday, proud grandma Kris Jenner shared a snapshot of son Rob Kardashian holding newborn daughter Dream Renee, and the momager wrote on Instagram, “This face says it all and melts my heart… @robkardashian … that smile ain’t nothin but a DREAM congratulations Rob and Chyna!! @blacchyna #love #family #dreamcometrue @dream."

“Today was amazing … I am so lucky!!" Rob added on social media just a few hours after his fiance delivered their first child via C-section on Thursday. "Thank you @blacchyna for having our baby and being so strong ! I love you so much and can’t wait to see her get older day by day with you Chy! I love you and Dream so much and Appreciate both of you. I know everyone saying that’s my twin but that’s def your nose Chy lol."

Kris was there for the delivery, as was Chyna's mom. "I got to watch [the] delivery," Jenner told E! News. "It was so beautiful and I'm so excited and happy to have another grandchild! No. 6! It was one of the most precious moments of my life." Khloe Kardashian, Scott Disick and Kourtney Kardashian stopped by Cedars-Sinai as well, along with Chyna's BFF Amber Rose.

Get it girls! Of course, we'd like this even better if Britney Spears and Kate Hudson did the mannequin challenge together, but whatevs...

Someone in Britney's tour squad took a video of the star and all of her backup dancers frozen in time on the stage in Las Vegas, and they absolutely nailed it. "We use our bodies to make our own #MannequinChallenge," Spears captioned the video.

Meanwhile, Kate was at a weekend party in Malibu with some famous friends like Rachel Zoe and Courteney Cox, and aside from a few squirmy children, most everyone in the clip knocked it out of the park as well. Kate's slightly less famous friend, Sara Foster, was the one who posted it on Instagram, and she captioned the clip, "Mannequin Challenge Take 86."

LOL. Who's next?!

Joe Manganiello and Sofia Vergara celebrated a friend's birthday at Catch in West Hollywood on Friday night, and the duo were all dolled up for the occasion. Other famous faces at the hotspot included Steven Tyler, Rita Ora, Leslie Mann and Judd Apatow -- sounds like quite the party!

"They were super flirtatious and made it clear they're still floating on the newlywed cloud," a source told E! News. "When they socialized around the main dining room, they were always hand in hand."

Sofia and Joe tied the knot on November 22 last year in Palm Beach, Florida, so we imagine we'll see them out and about more over the next week or two to celebrate their one-year wedding anniversary!

Katy Perry donated $10,000 to Planned Parenthood on Friday and told told her millions of fans that it's "time to turn words into action."

“I am making a public donation to Planned Parenthood for the teenage me who made several visits to first a clinic in Santa Barbara and then Los Angeles, CA to educate myself on my sexual health, a subject I had little to no information on because of my sheltered upbringing,” she wrote in an Instagram post. “I had no idea how things worked down there, and had no idea how to make a plan for them.”

Perry, who has been a Hillary Clinton supporter from the get go, added that “without this education, I may have had a different life path.” She continued, “I know what it’s like to need help. I came from a lower- to middle-class family and never grew up with the option of health insurance. I remember having 13 cavities as a teenager, and the best option my parents could come up with was to try and take me to Mexico because we couldn’t afford anything in California."

Ashley Tisdale and her husband Christopher French went for a hike in the Hollywood hills on Saturday, and though the couple attracted the glances of some fellow hikers, they didn't seem to mind!

Ash and her man have been married for over two years now, and they recently celebrated their anniversary in New York City. “In NYC doing touristy things,” Ashley captioned a shot of the couple before visiting the Statue of Liberty. And you may not know this, but Chris proposed at the top of the Empire State Building, so the Big Apple is very special to them.

They honestly seem like one of the most normal showbiz couples around!

Exactly a year after The Bataclan in Paris, France was hit by a deadly terror attack that left 90 people dead at the venue, they re-opened their doors last night, with Sting as their special guest.

“We've got two important things to do tonight," Sting told the crowd, before observing a moment of silence. “First, to remember and honor those who lost their lives in the attacks a year ago ... and to celebrate the life and the music of this historic venue ... We shall not forget them.”

The massacre took place during an Eagles of Death Metal show, and in addition to the 90 fatalities at the club, a total of 130 people were killed in Paris that night in the coordinated attack. After the tragedy, members of the band accused staff at the venue of being "in" on the plot. As it turns out, they tried to gain admittance to the show last night, and they were turned awa. "They came, I threw them out — there are things you can't forgive," Bataclan co-director Jules Frutos told Agence France-Presse.
