ABC has announced the cast for the upcoming season of 'Dancing with the Stars'.

Among those who will be competing for the disco-ball trophy will be reality star Kendra Wilkinson [photos] ('The Girls Next Door'), supermodel Petra Nemcova, actress Kirstie Alley (Cheers), 'Karate Kid' star Ralph Macchio and boxing legend Sugar Ray Leonard.

The cast was announced Monday by "Dancing" hosts Tom Bergeron and Brooke Burke in segments that aired during an episode of ABC's 'The Bachelor'.

Also hitting the dance floor will be actress WWE wrestler Chris Jericho, actress Chelsea Kane (formerly Staub), talk show host Wendy Williams, Loveline co-host Mike Catherwood, Pittsburgh Steelers wide receiver Hines Ward and onetime rap star Romeo.

Kirstie Alley suggested that the contestants' focus would be to "try not to fall on our butts the first week out. That's what I'm going for."

While the boxer said he had another approach altogether: "I think it's all psychological. I think it's spiritual," said Leonard. "I think it's all the mental preparation."

"Have you ever watched the show?," quipped Bergeron.

Last season 'Dirty Dancing' actress Jennifer Grey, who was paired with dancer Derek Hough, took home the prize. The twelfth season of the dance competition will premiere on March 21.
