MONACO: After waiting decades for Prince Albert II to choose his bride, residents of this high-flying Riviera principality are preparing to embrace South Africa's Charlene Wittstock to succeed Grace Kelly as Princess of Monaco. The striking blond Wittstock, a 33-year-old former Olympic swimmer, will be transformed from commoner into princess in a civil ceremony in the throne room where Hollywood beauty Kelly married Albert's father, Prince Rainier III, 55 years ago. The wedding continues Saturday, with an even more elaborate religious ceremony and opulent gala with a guest list including heads of state, European royalty and the creme de la creme of the fashion and sporting worlds. With her bright blue eyes and even features, Wittstock has won comparisons with Kelly, who died in a car accident nearly three decades ago. Wittstock is expected to wear an ensemble by coveted Paris label Chanel.
