Los Angeles ? 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.”

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.”
