Rob Kardashian's Disturbing Instagram Post Explained

Rob Kardashian shocked a ton of people when he compared his older sister Kim Kardashian to the psychotic “bitch from Gone Girl“ in an Instagram post this weekend.

Now, a family source is opening up to People, saying that this is just part of the 28-year-old reality star’s sense of humor.

“He has a funny sense of humor and posts weird things and then deletes them,” the source said. “It’s just him.”

“He’s been depressed and just a bit off in general,” the source added of Rob, who has been battling with his weight in recent years. “But he has always been this way. He just can’t lose the weight and he doesn’t try – he just sits around.”
