Rob Kardashian hides his face in cryptic new selfie

Rob Kardashian came out of hiding early Wednesday morning.

The 28-year-old Keeping Up With the Kardashians star shared a rare selfie, but kept his face covered with a bandanna. He captioned the photo with two sad face emojis.

Rob also deleted all prior Instagram posts, including his recent joke about losing the Powerball and his pic of Kanye West covered in donuts.

This cryptic Instagram pic comes just a week after momager Kris Jenner claimed that her reclusive son would be returning to the family's reality show. "He just wants to feel good. It's not that he doesn't want to be on the show, it's just he wasn't feeling good," she told Maria Shriver at the Architects of Change: The Conversation Series. "He was depressed, you know, just wasn't feeling good, didn't know why."

Earlier this month, it was revealed that Rob was diagnosed with diabetes. Following this news, a source told ET that he had also moved out of Khloe's home and was living on his own at a condo in a gated community in Calabasas, California.
