The lineup for the 11th season of the TV dancing contest, set to premiere on Sept. 20, will also include crooner Michael Bolton, reality TV star Mike Sorrentino, and actress Jennifer Grey, who twirled to fame in the film "Dirty Dancing." Palin, 19, a single mom, is following in the reality TV footsteps of her former fiance, Levi Johnston, whose small-screen adventures involve running for political office in Alaska - and whose off-screen adventures have put him at odds with her mother. She said she hoped her mother, the former Alaska governor and US vice presidential candidate, would be on hand to watch her pair up with a professional dancer on the ballroom floor and compete against other celebrity/dancer couples.
