While we know that he missed Kim Kardashian and Kanye West's wedding and he hasn't been out in public much, we haven't been let in on what is really going on with Rob until now.
In this sneak peek from this week's episode, Kris Jenner brings in someone that she thinks can help Rob. "I feel like if I don't help him do something drastic...that he's gonna die," Kris confesses to Kim as she's explaining her reasoning for bringing the professional in.
When the guy arrives, Kris lays it all out on the line, explaining that he used to be so athletic and he's gained over 100 pounds in the last year. Now, he doesn't want to participate in stuff, he doesn't want to leave the house, he's missed Christmas AND Kim's wedding and Kris breaks down in tears just talking about it.
We really hope that this guy and his team are able to help Rob because we really miss seeing him and it's very clear that his family does, too.
