Look who's dancing now.Once again, Kirstie Alley found a way to make herself the center of attention on "Dancing With The Stars," but instead of falling or having a wardrobe malfunction, she got a little help from a famous friend. John Travolta, who redefined Hollywood dancing in the '70s with "Grease" and "Saturday Night Fever," and co-starred with Alley in the "Look Who's Talking" films, showed up to coach Alley and her partner, Maksim Chmerkovskiy.Chmerkovskiy did his part, too -- he bared his chest, on which an American flag was painted, for their fox trot.
