Season 9: Kelly Osbourne takes a tumble
Kelly Osbourne landed on her bum in part one of the "Dancing With the Stars" finale. After she and partner Louis Van Amstel attempted a difficult twist move, Osbourne hit the ground, but got up to finish. Judge Bruno Tonioli comforted her, saying, "You have all the glitz and glamour of the disco era ... sometimes people fell on the floor. It was part of the night."
