The pair posted a score of 51.97 to sit fourth early in the short dance competition.

"Don't stop that, pull it off. Let that motherf***er come off. You dance your ass off girl. Oh s***, just pull the sleeves up when you do that move. That's a soldier right there. She ain't going to stop. I wouldn't stop. I'd want my titties to be out. We've been working too long for this."
