The seventh season of the competitive reality series Dancing with the Stars is the first to line up 13 couples rather than 12 in the ballroom dance contest designed to crown one pair the season winner. Some of the celebrities that grace the floor with a professional dance partner during this season include Lance Bass, Toni Braxton, Brooke Burke, Susan Lucci, and Cloris Leachman - who, at 82, is the oldest contestant ever to join the Dancing with the Stars cast. ~ Cammila Albertson, Rovi
