Sandra Bullock says she has filed for divorce from her husband, Jesse James. In a story posted Wednesday on People magazine's Web site, the Oscar-winning actress also reveals that she and James adopted a 3 1/2-month-old boy, Louis Bardo Bullock, who was born in New Orleans. The report says Bullock and James began the adoption process four years ago and brought Louis home in January but decided to keep the news to themselves until after the Oscars.
