The mother of "The Brady Bunch," a former NFL quarterback, one of the self-proclaimed "guidos" from "Jersey Shore" and the daughter of Sarah Palin are among the celebrities who will cha-cha-cha on the 11th season of "Dancing with the Stars."

Tom Bergeron and Brooke Burke, hosts of the ABC ballroom competition, announced the cast Monday.

"The Brady Bunch" matriarch Florence Henderson, retired Arizona Cardinals quaterback Kurt Warner, "Jersey Shore" co-star Mike "The Situation" Sorrentino and Bristol Palin are among the 12 celebrities who will be paired with professional dance partners and train before their primetime premiere Sept. 20. How does Palin's mother feel about her dancing gig?

"She's excited for me," said Bristol. "She knows that this is going to be hard work, but she's excited."

Also competing for the mirrorball trophy will be: "When a Man Loves a Woman" singer Michael Bolton, comedian-actress Margaret Cho, former Los Angeles Lakers forward Rick Fox, "Dirty Dancing" actress Jennifer Grey, "Baywatch" actor David Hasselhoff, Disney Channel star Kyle Massey, singer-actress Brandy Norwood and "The Hills" co-star Audrina Patridge.

"My two daughters love this show," said Hasselhoff, "and they convinced me."
