Swimmer Natalie Coughlin among new “Dancing with the Stars”

Natalie Coughlin can do the backstroke and the breastroke in world record time, but can she do the tango?

Coughlin, who has made a big splash in the Olympics, will attempt to excel in the ballroom during the upcoming season of ABC’s “Dancing with the Stars.” She was among the 16 celebrities named to the “Dancing” cast, as announced Monday morning. She’ll compete against the likes of former Republican Majority Leader Tom DeLay, pop singer Donny Osmond, and former Dallas Cowboys wide receiver Michael Irvin.

Other hopefuls include 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; and professional snowboarder Louie Vito.

The contestants were announced on Monday’s “Good Morning America” by “Dancing” host Tom Bergeron, who 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.”

Coughlin represented the United States at the 2004 and 2008 Summer Olympics. In 2008, she became the first American female athlete to win six medals in one Olympics.

After taking a break from swimming competition after the 2008 Beijing Olympics, Coughlin will be extending that break with time logged on the dance floor. She appears to be in good company on “Dancing” as three Olympians have won the reality show’s coveted title. Speed-skater Apolo Anton Ohno captured the prize in Season 4, while figure skate Kristi Yamaguchi prevailed in Season 6 and gymnast Shawn Johnson won the disco-ball trophy in Season 8.

The ninth season of the hit ABC show premieres Sept. 21.
