Well, that was quick! Earlier this week, Sandra Bullock debuted a new blonde ‘do on the set of her latest flick, Our Brand Is Crisis, in New Orleans. In the comedy, which pal George Clooney produced, the Oscar winner plays a retired American political consultant. But it appears her lighter locks may have been a wig, as the beauty was back to her signature dark tresses a mere two days later. Otherwise, that was one short-lived dye job! The 50-year-old actress is no stranger to being blond in a movie. In 2009, she switched to lighter locks for her roles in The Blind Side and All About Steve.
