Valerie Harper leads a class of 12 amateur hoofers in the upcoming 17th season of "Dancing With the Stars."

The cast was revealed Wednesday on ABC's "Good Morning America." For a show that has reached an increasingly older audience, ABC added an injection of youth with reality stars Nicole "Snooki" Polizzi of "Jersey Shore" and Ozzy's kid Jack Osbourne.

Harper has been busy, despite a cancer diagnosis earlier this year. She recently filmed a movie role and joined a Nick at Nite reunion of "The Mary Tyler Moore" cast.
