Season 13′s cast of ‘Dancing With The Stars‘ was just announced last night, and among the celebs this year is Kim Kardashian‘s younger brother Rob! However, there is a very specific reason why Rob decided to do the show…

Rob Kardashian wants to drop some pounds!

He told US Weekly, “I really want to get into shape! You probably wouldn’t know, but I’m the most insecure and overweight I’ve ever been. I’m over 200 pounds, so I want to drop weight and this will be a good start.“

Well now we’recurious, does Rob have any dancing skills? He said, ”I’m not a confident dancer at all. And down the road… I don’t want to be that guy who doesn’t dance at his own wedding!”

Sooo did sister Kim have any advice for her baby bro?? “She just said, like ‘You’re going to be really nervous.’ [But] I don’t want her advice – I don’t need advice from someone who lasted, I think three weeks.“
