David Arquette Exposes Rob Kardashian's Secret Weapon!

David Arquette is taking his new role on Dancing With the Stars seriously, and has recently studied enough of Rob Kardashian to figure out his secret weapon…

… his booty!!

“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.”

LOLz!

We can’t wait to see if that’s true! Though, we don’t think you’ll be at such a disadvantage, though, David. You’ve got those “electrocution” moves!

“When I dance, I look like I’m being electrocuted. Apparently there’s no real room for that in ballroom dancing.”

Sure there is! Ha!

Good luck to both of you!
