At 76, beloved "Brady Bunch" mom Florence Henderson is season 11's oldest star.
"I want to be fun and sexy and really shake it up, you know?" she said.
The youngest two are both 19.
"It's pretty hard to cut off my energy," said actor and rapper Kyle Massey. "I pretty much have like an unlimited supply. They call me the Sun, mainly because they don't know what fuels my energy. It just doesn't end."
The other teen is Bristol Palin.
"I'm just a down-to-Earth girl," Palin said. "I'm an Alaskan girl. I hunt, I fish, I'm kind of a tomboy. I'm stepping out of my comfort zone and I'm just going to enjoy myself."
When it comes to that enjoyment, she's not alone.
"I can't wait to dance and I can't wait to compete," said actress and comedienne Margaret Cho. "I can't wait to put on some sequins and eyelashes and go for it."
So was her reality TV star competitor.
"I'm looking forward to the costumes, hairstyles, learning all these glamorous sexy dances and all the music. Everything about it," Audrina Patridge said.
Actress Jennifer Grey said she just wants to get past the first week, a sentiment echoed by another star.
"It's like jumping out of an airplane," said actor and singer David Hasselhoff. "You just hang onto your partner and hope that chute opens and then if you land, you make the next round. That's it."
Singer Michael Bolton and "The Jersey Shore's" Mike "The Situation" Sorrentino are also dancing, but could not make the press conference.
Two big sports stars are also ready to give it a go.
"You're going to be wondering the whole time, what do people think?" said former NFL quarterback Kurt Warner. "What are people seeing? Am I any good at this at all?"
Rick Fox, a former Laker and current actor, approached it a different way.
"I miss competition," Fox said. "I miss competing and, last I saw, there's a trophy at the end of this and it'd be nice to get my hands on it."
One star is just happy for the opportunity to dance after living through the nightmare of being involved in a fatal freeway accident.
"I am going to dance until I can't dance no more," said singer and actress, Brandy. "I'm ready to come back. I'm here."
Season 11 of "Dancing With the Stars" kicks off Sept. 20 on ABC.
