ralph macchio dwts 320 'Dancing With the Stars': Ralph Macchio, Chelsea Kane, Petra Nemcova in Season 12 castLadies and gentlemen, your “Dancing With the Stars” Season 12 cast. Or at least part of it.

ABC announced the new dancers in two waves Monday night (Feb. 28) during “The Bachelor.” Here’s the first set of celebs who will test their ballroom skills come March 21:

Sugar Ray Leonard: The former boxing champ had a cameo as himself in “The Fighter.”

Chelsea Kane: You may know her better as Chelsea Staub. She starred in “Jonas L.A.” and the Disney Channel movies “Minutemen” and “Starstruck.”

Romeo: Don’t call him “Lil’.” The singer and actor is the son of former “DWTS” contestant Master P.

Ralph Macchio: The original “Karate Kid.” We really, really hope his partner figures out a way to work the crane pose into his choreography.

Petra Nemcova: The supermodel couldn’t be at the announcement, because she was speaking at the United Nations Monday. That’s a pretty good reason.

Part two of the cast announcement is right here.
