Bristol Palin Shows Off Her Sexy Booty At Dancing With The Stars Rehearsals

Bristol Palin was snapped arriving at a rehearsal for Dancing With The Stars on Sunday, and the 21-year-old starlet looked tan and toned, showing off her booty in a pair of grey spandex.

When asked about shedding the pounds, Palin told Us Weekly, "I'm definitely in better shape than I was last time ... I'm just more active and I cut all the crap out of my diet! It's that simple. And my kid's a lot more rowdy, a lot more active. I'm running after him a lot! He's huge! He thinks he's a teenager already."

Partner Mark Ballas weighed in, adding, "It's definitely a step in the right direction. She looks amazing, and I definitely can feel it when I move with her. She's more smooth."

Last week Pamela Anderson was sent home, so it could be anyone's game! Click the gallery below to see the rest of her DWTS co-stars at practice, including Val Chmerkovskiy and Kelly Monaco getting a bit frisky!
