Shock rocker Ozzy Osbourne's 5-month-old daughter, Aimee, made her press debut in New York with customary British aplomb. Daddy, 35, was in town to promote his newest LP, Bark at the Moon, and perform at Madison Square Garden. Fatherhood seems to have mellowed old Oz; these days he no longer bites the heads off bats as part of his act. Meanwhile, Ursula Andress, 47, and Dimitri, her 3-year-old son by actor Harry Hamlin, were among the spectators who gathered across the street to gape while Burt Reynolds directed the final scene of his new film, Stick. While Ursula and Dimitri were wide-eyed with wonder as stuntman Dar Robinson leaped 200 feet from a balcony at the Grove Towers in Coconut Grove, Fla., everyone else was gazing with wonder at Mommy. Still looking good.
