Here is a roundup of the stars who will learn to salsa in the upcoming season.

It was later revealed that the mastermind behind her attack was the ex-husband of her rival American figure skater Tonya Harding, who eventually pleaded guilty to charges related to the attack. Kerrigan is executive-producing an upcoming documentary, "Why Don't You Lose 5 Pounds?" which looks at the epidemic of eating disorders in sports.
