They'll compete against supermodel Petra Nemcova, sportsman Hines Ward, retired pro boxer Sugar Ray Leonard and DJ Mike Catherwood in the contest, which is set to premiere later this month (Mar11).

Kirstie Alley is looking forward to appearing on the show - and is hoping to avoid any falls during her debut dance: "I think we're just here and trying not to fall on our butts the first week. That's what I'm going for."
