The twelve new celebrity dancers and their professional dance partners finally took over the dance floor to show their dancing skills for the first time at the Dancing With The Stars season 13 premiere on Monday (September 19). Kristin Cavallari and her partner Mark Ballas danced the Cha Cha to the sound of “Dynamite” by Taio Cruz (watch video below).

Kristin is NOT a b*tch. You have been warned. She looks fantastic on that dance floor. She has a fiery and fun personality, and Mark loves to push the envelope with his stunty routines, which is a perfect combination. I wasn’t exactly impressed since the performance was kind of poor, but I see lots of potential in this pairing.

Len Goodman was pleased with the bright and lively performance, but thought Kristin sort of hidden some of her flair in her shell. Bruno loves a bad girl with good hips ready to offer than some hot action, but he wanted Kristin to work on her unsteady turns. Carrie Ann Inaba was impressed with the hair-ography part and complimented her quality of movement.

Score: 19 (7+6+6)
