Margaret Cho Among Dancing with the Stars Contestants

Dancing Star: Standup comic and actor Margaret Cho will vie for the mirror-ball trophy.

A Korean American standup comic who starred in the series All-American Girl, 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.

Comedian-actress Margaret Cho, “The Brady Bunch” matriarch Florence Henderson, retired Arizona Cardinals quarterback 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 prime-time 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, 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.

“I’m happy to be here,” said Hasselhoff. “My two daughters love this show, and they convinced me.”

The names of most of the celebrity contestants, save for 19-year-old “That’s So Raven” and “Cory in the House” star Kyle Massey, had been widely rumored as competitors in the weeks leading up to Monday’s official announcement, which was broadcast live during “Bachelor Pad.” The first celebrity and their professional partner will be eliminated Sept. 21.
