They're scandal-less. At last, the world has a royal couple unlikely to inspire Sunday-night movies featuring ex-cast members from Falcon Crest. Donning 11th century garb, Japan's CROWN PRINCE NARUHITO wed the multilingual MASAKO OWADA in a solemn, 14-minute Shinto ceremony at Tokyo's imperial palace. After, Masako, who began the day with a farewell to her parents and pup Chocolat, changed out of a 30-lb. kimono and into Western wedding wear to greet crowds from a 29-vehicle motorcade. Well-wishers hit the streets and the airwaves. Even Brooke Shields offered the royals a televised good luck.
