Surgically-enhanced Bristol Palin and Pamela Anderson are both looking sexy and slim in the new promo shots for the upcoming season of Dancing with The Stars All-Stars.

Sarah Palin's 21-year-old daughter, and mother of one, first appeared on the hit dancing show with partner Mark Ballas during the 11th season. Of course, this was pre-surgery.

One more surprise couple will be added to the cast, but the announcement won't be made until August 27.
