(Cover) - EN Showbiz - Khlo Kardashian admits that she acts like a "stage mom" when watching her brother perform on Dancing with the Stars.

Rob Kardashian is a contestant on the latest series of the US TV show. Khlo admits that watching her sibling perform routines on the programme brings out her maternal traits.

"I went to a tonne of his rehearsals; I was such a stage mom," Khlo told reporters at the T-Mobile Samsung Factory 4G Live event in New York City on Wednesday.

"I was like, Smile! Smile. Do it again!' I'd videotape him so he could see it."

Dancing with the Stars is a family affair. Khlo's sister Kim Kardashian was a contestant on the show in 2008. Khlo, Kim and the rest of the Kardashian clan are extremely supportive of Rob's efforts.

"We were all there the first night he danced. It's just so cool to see his confidence grow," Khlo explained. "I've definitely seen different sides of him that I didn't think he'd be able to do. So I definitely was a little crazy but he's doing so amazing. I'm just really proud of him."

Although Khlo respects Rob for appearing on the show, she confesses that it would be unlikely that she would follow in his footsteps.

"I want to vomit. I get so anxious, it's not like good. Mondays and Tuesdays. They're so stressful," Khlo said.

"I could never do that show. If I can't watch him, I don't think I could do it." (C) Cover Media
