The rumors we reported earlier came true: 'Cheers' star Kirstie Alley and former Hugh Hefner girlfriend Kendra Wilkinson were both on the official roster. And while Tea Party candidate Christine O'Donnell didn't end up joining 'DWTS' (and neither did Joy Behar, despite our wish list), pro wrestler Chris Jericho and talk show host Wendy Williams will be among the celebrities shaking their hips.
Two of the bigger names on the cast are actors who broke out in the '80s -- Kirstie Alley and Ralph Macchio. Can the 'Cheers' star and the 'Karate Kid' have a shot at following in the foosteps of Jennifer Grey, who starred in the classic 'Dirty Dancing'?
So why did Alley decide to go 'Dancing'? "Hmm, why?" Alley mused. "I don't know, pass that to someone else!"
When 'DWTS' alum and 'Good Morning America' correspondent Cameron Mathison asked her how she'd make herself more likable, Alley responded, "I think we're just here trying not to fall on our butts the first week!"
Macchio told co-host Brooke Burke he hoped his 'Karate Kid' skills would come in handy in learning choreograph. "I guess I just have to point my toes this time," he laughed.
Season 12 also features rapper Romeo, who was slated to dance in season 2. But he was injured in a basketball game and his father, Master P, stepped in to compete.
