Glitter star Mariah Carey gave birth to twins—a girl and a boy—on Saturday, her fourth wedding anniversary with her husband, the guy from All That. Neither child has yet been named. Like most expecting parents, the couple drove to the hospital in their Rolls-Royce Phantom; according to Carey's publicist Cindi Berger, Cannon "was so nervous he went to the wrong department at the hospital." Carey is apparently "done" with having children. [AP]
