You wouldn't exactly say the relationship between Christopher Knight and Adrianne Curry has mellowed since the first season of My Fair Brady. But the 48-year-old Brady Bunch star and his 23-year-old fiancée, winner of America's Next Top Model Season 1 and a nonstop talker, are less abrasive this time. They're almost cute—and the show's better. They still squabble over issues small (the cost of his tuxedo) or large (whether he should get a vasectomy). But cultivating love in the hothouse of reality TV can't be easy. She sometimes conveys real insecurity about losing him. "I don't have cold feet," Knight reassures her, "just chilly toes."
