On Wednesday's Late Night with David Letterman, newly appointed Dancing with the Stars contestant David Arquette spoke to Dave about the brand new cast, in particular Robert Kardashian who he couldn't help but to compliment on his "great ass."
Arquette goes on to praise Rob's backside as "fantastic. I really think it's going to be his secret weapon."
Only time will tell if Robert's "secret weapon" will bring home the mirror ball. Sister Kim was the third contestant to get the boot in season seven.
