Move over, Kim Kardashian—your brother Rob says he's a better dancer.
And his Dancing With the Stars partner Cheryl Burke actually said during last night's premiere that he has more potential than his sister, too.
Uh-oh. How'd that go down with the Keeping Up With the Kardashians bunch?
"Kim knows it," Rob said of Burke's remark. "She wants me to do better than her. She wants me to go further than she did. I think it's a known thing that I'm better."
Kim, Kourtney and Khloé and hubby Lamar Odom were in the audience cheering him on. Cameras caught Kim saying, "I'm going to cry." During the critiques, Khloé even heckled Bruno Tonioli for his not-so-nice remarks.
Kardashian and Burke scored a 16 for their Viennese Waltz. Not the best, but still enough to beat Elisabetta Canalis and Val Chmerkovskiy and Ron Artest and Petra Murgatroyd.
"They were saying to feel the music more," R.K. said of the judges' critiques. "I understand everything they're saying and I agree with them."
He said he expects romance rumors to start flying about him and Burke because "that's part of the game."
Part of the game is also getting the better-looking contestants to show as much skin as possible. Kardashian says he's not ready to go shirtless...yet.
"If I get in better shape, we'll see how revealing it will be," he said.
