The frothy white gowns that made their way down the Dior couture runway Wednesday caught the eye of at least one famous bride-to-be in the front row. "I'm shopping for my wedding dress," cooed Christina Aguilera, who added that Christian Lacroix and Givenchy were also possible bridal picks. Drew Barrymore was more coy, although rumor has it she soon may be walking down the aisle again. "This is my first Dior show. It is all very new to me," said the actress, taking time out from filming "Lucky You." After locking lips for the cameras with her fiancé, Fabrizio Moretti, Barrymore hinted she also was working on a commercial for South America, blushing when asked to reveal more. Elsewhere, the paparazzi crush reached dangerous proportions with the arrivals of Chinese actress Ziyi Zhang and Charlize Theron, who just wrapped up "Class Action," a movie about the first big sexual harassment case in the U.S. But other cameras soon will be turning. Theron, the face of J'Adore, said she would be spending the next few days in Paris posing for new Dior fragrance ads. "I've always liked fashion," she quipped. "It's a serious art form."
