Kim Kardashian is finally weighing in on Rob Kardashian’s disappearance.
"It's not that mysterious, what's happening with Rob," the pregnant 34-year-old told Rolling Stone.

"He has gained weight. He feels uncomfortable being on the show [Keeping up with the Kardashians], and that's OK. Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes."

It’s clear Kim is still taking the “tough-love” route when it comes to the 28-year-old’s condition. Their mother, Kris Jenner, has previously admitted in April he's gained over 100 pounds, and even skipped Kim's wedding to Kanye West last May because he was not feeling great about himself.
Fans speculated there was a sibling feud between the two when Rob compared Kim to Rosamund Pike's Gone Girl character in a vulgar Instagram post. They appeared to be getting along as of late.
