Another day, another dance!
Rob Kardashian arrived at Dancing with the Stars rehearsal Thursday afternoon, just after taping a segment for Extra at The Grove in LA ... in the same rolled up pants!
Not that there was any doubt, but Rob proved that he is definitely a Kardashian by showing off his butt as he strut into the practice space. And according to fellow DWTS contestant David Arquette, his "fantastic" booty is "going to be a secret weapon."
Now that's one cool secret weapon! But please, Rob, just toss those pants out already!
Check out more pics of Rob and other DWTS stars (like a gorg Kristin Cavallari!) below.
The entire Kardashian clan is just full of bootylicious kids!
