Which Kardashian Would Never Do Dancing With the Stars?

One member of the famous reality family says they couldn't dance on the hit ABC show...find out who it is!

Kim and Rob Kardashian have already competed on Dancing With the Stars, but one member of the famous E! family says you'll never see them doing a cha-cha for the crowd on the ABC show.

"Mondays and Tuesdays, I want to vomit," they said last night. "I love watching him [Rob] but...you get sick the whole day and that's not fun because you're nervous. So I could never do that show because if I can't watch him, I don't think I could do it!"

Which family member gets anxious just from watching?

It's supportive sis Khloé Kardashian Odom, who says she's a total stage mom to her younger bro (in a good way).

"I went to a ton of his rehearsals and I was like...'You gotta smile! Smile!' I would videotape him so he could see it," she shared at the T-Mobile Android-Powered 4G Devices launch party last night. "I definitely was a little crazy but he's doing so amazing and I'm just proud of him."

But we're sure if she ever changed her mind, Rob would be happy to return the favor and coach her in return!
