Fame not responsible for Rob Kardashian's problems- Kim K

Kim Kardashian has opened up on Rob's weight battle..In a preview clip of an intervview with Matt Lauer, she says 

"I think he's just going through a phase where he's not comfortable in his own skin,And he is working really hard to get back to where he really wants to be."

 Lauer replied

"All kids, as you put it, go through phases, "But is his phase being exacerbated by the fact that he is part of this very public, very famous family?"

Kim then said

"I don't necessarily think it's because of the fame, "I think it's been circumstances in his life that he just really hasn't dealt with. Whether it's, you know, the loss of our father, or certain breakups, or, you know, he was extremely close to Lamar [Odom] and when, you know, Khloé and him broke up, that was really hard on him. So I think it was a couple things."
