The 12 celebrities heading to the dance floor this season include Michael Bolton, Brandy, Margaret Cho, Rick Fox, Jennifer Grey, David Hasselhoff, Florence Henderson, Kyle Massey, Bristol Palin, Audrina Partridge, Mike "The Situation" Sorrentino and Kurt Warner.

Hosted by Tom Bergeron and Brooke Burke, the celebrities, who are each paired with an accomplished dancer, perform choreographed dance routines that are judged by Ballroom judge Len Goodman and dancer/choreographers Bruno Tonioli and Carrie Ann Inaba.

The couple with the lowest combined judges' scores and public votes for their performance will be sent home on Sept. 21.
