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.
