 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 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, 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. 
 
 "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.

 It didn't seem possible that "Dancing With the Stars" could outdo itself in the casting department. After last season's winning combination of Kate Gosselin Shannen Doherty and Pamela Anderson , senior producer and head of casting Deena Katz decided she had two choices: retire or up her game.Katz opted to challenge herself and wound up with a Season 11 cast that is bound to get the whole country on its feet.Seriously, Mike "The Situation" Sorrentino ("Jersey Shore") is going to cha cha cha and compete against singer Michael Bolton , Kyle Massey ("Cory in the House"), recently retired NFL quarterback Kurt Warner , retired basketball player Rick Fox and David Hasselhoff The women competing for the coveted mirror ball trophy are: Jennifer Grey (yes, Baby from "Dirty Dancing"), singer Brandy , "Brady Bunch" mom Florence Henderson Audrina Patridge ("The Hills"), comedian Margaret Cho and Bristol Palin "It's like putting together the most bizarre and yet entertaining kind of dinner party," Katz said of the casting process. "I make a jigsaw puzzle of including something for everybody. And what I think works best is, let's say you watch because you love David Hasselhoff and you have no idea who Margaret Cho is — what I love is this idea that you go in watching The Hoff but you then fall in love with Margaret."This cast, said Katz, is her "dream team." Since the show launched in 2005, she said she's been "stalking" Hasselhoff and Grey to be a part of it every season. But they both had prior commitments and reservations about joining."It takes a big leap to do the show, and I get that people have fear and they have commitments," Katz said. "What you don't realize is that besides the 10 weeks of the show, there are three or four weeks of rehearsal time. Jennifer had some concerns because of 'Dirty Dancing.' She knows everybody wants to see her on the show."Although the entire cast is made up of people that Katz said she approached, these days producers are bombarded with requests from interested celebrities. It wasn't always that way."Calling people before we were on the air in Season 1 and saying, 'We're going to do a live ballroom dance show with celebrities,' you could hear the clicks of the phone," Katz said.Now, people are more open to it, even those Katz thought were longshots, like Sarah Palin 's 19-year-old daughter, Bristol."You ask and you never know," she said. "I can tell you this, she's the only one that when I asked her to join the show, she packed up her truck and drove all the way from Alaska. I always try to have people you'd never expect… And this season, some of the names make you chuckle, others you're surprised about, and others you think you know, but you're going to see them in a different light."
– Dancing With the …Trainwrecks? Yep, Bristol Palin, Mike “The Situation” Sorrentino, and David Hasselhoff are among the more infamous members of the newest Dancing With the Stars lineup. Don’t worry: It does get classier. How can it not, when it includes ‘90s crooner Michael Bolton? And fellow darling of that era Jennifer Grey? (That's right, Baby.) The rest of the Stars, who you can catch on the Sept. 20 premiere, are: The Brady Bunch’s Florence Henderson retired quarterback Kurt Warner comedian Margaret Cho former NBA player Rick Fox Disney star Kyle Massey singer Brandy Norwood Hills star Audrina Patridge The casting agent called the crew her "dream team" and "the most bizarre and yet entertaining kind of dinner party." Deena Katz shares a Bristol tidbit, too, by way of the LA Times: "She's the only one that when I asked her to join the show, she packed up her truck and drove all the way from Alaska."
