David Arquette Thinks Rob Kardashian Has a "Great Ass"

Us Weekly certainly knows how to get our attention. They quoted an interview with David Arquette (from an episode of The Late Show With David Letterman) where he talked about fellow Dancing With the Stars contestant, Rob Kardashian.

Arquette said this about is costar: "The thing about Rob is, and a lot of people don't know this, but he's got a great ass just like his sister. I'm serious! Once you see it, his ass is fantastic. And I really think it's going to be a secret weapon."

As if to prove the point, sister Kim Kardashian took a shot of her brother's bootie (in slacks) and posted it @KimKardashian with the quote, "Guess who has the biggest butt in the fam?"

Good times.
