MONACO — A day after the civil wedding that transformed one-time Olympic swimmer Charlene Wittstock into the Princess of Monaco, she and Prince Albert II wed in a star-studded religious ceremony Saturday. The couple exchanged 18 carat white gold platinum rings by Cartier. As Albert slipped the ring onto her finger, he winked, and as she put his on, she burst out into a broad smile. The bride appeared to tear up behind the veil as the South African took her place at the altar inside the princely palace where the Catholic ceremony was taking place.
