Former Republican Majority Leader Tom DeLay will join 15 celebrities from the worlds of entertainment and sports in kicking up their heels on the new season of "Dancing With the Stars.
Other hopefuls include entertainer Donny Osmond; singers Mya, Macy Gray and Aaron Carter; actors Melissa Joan Hart, Debi Mazar and Ashley Hamilton (son of George); models Joanna Krupa and Kathy Ireland; reality stars Kelly Osbourne and Mark Dacascos ("the Chairman" on Food Network's "Iron Chef America"); mixed martial artist Chuck Liddell; professional snowboarder Louie Vito; Olympic swimmer Natalie Coughlin; former Dallas Cowboys wide receiver Michael Irvin and the 62-year-old former congressman from Texas.
The contestants were announced on Monday's "Good Morning America" by "Dancing" host Tom Bergeron.
He also unveiled a new competitive twist.
"In the middle of our season, over three weeks, we're going to have double eliminations," said Bergeron. "We'll lose about half of our cast within that period. It will be a ballroom bloodbath."
Samantha Harris returns as co-host, with the panel of judges including ballroom judge Len Goodman and dancer-choreographers Bruno Tonioli and Carrie Ann Inaba.
The ninth season of the hit ABC show premieres Sept. 21.
