Rob Kardashian Wants To Beat Sister Kim's Record & Get 'Ripped' On 'Dancing With The Stars'

Rob Kardashian wants to beat sister Kim Kardashian’s short three-week stint on Season 7 of “Dancing with the Stars” – in addition to gaining some abs.

“Three weeks I have to beat! I can’t lose to her,” Rob told Access Hollywood Live’s Kit Hoover when asked about his recently married sister’s record on Monday night, following the Season 13 cast announcement.

The 24-year-old member of the reality TV dynasty said he also hopes the hit ABC series will help him drop some weight, while possibly helping him work on his abs.

“Once I get six weeks going of rehearsals, and my weight drops a little bit, I will be confident,” he explained. “My goal is to get ripped! I’m the most weight I’ve ever been, so I really want to use this to get to the next step. “

According to Rob, his reality star sister was petrified of the competition.

“She told me she was terrified,” Rob revealed.” I know she was terrified.”
