'DWTS' Smackdown: Audrina Patridge vs. The Situation

"Dancing with the Stars" contestants Audrina Patridge and Mike "The Situation" Sorrentino gave "Extra" the lowdown on their premiere performances.

"I've got my dancing shoes, my dancing pants and I'm about to lose this shirt!" joked The Situation, but he did admit he's a little nervous. "I'll be honest with you... one of the reasons I took this challenge of 'Dancing with the Stars' is really because I'm not the best dancer."

Still, that's not stopping the Jersey boy from talking smack about castmate Audrina Patridge. When "Extra's" Mario Lopez told her The Situation said he was taking her down, Patridge laughed, "Good luck!" Her "DWTS" partner Tony Dovolani added, "He's not the only one with a six pack, don't you worry."

Tony and Audrina said they will be dancing the cha-cha to Katy Perry for their premiere performance. "It's really fun! It's upbeat," Audrina promised.

Finish your gym, tanning and laundry, and watch "Dancing with the Stars" when it premieres tonight on ABC.
