The world's worst-kept secret is finally out... Natalie Portman is the new face of Christian Dior's fragrance Miss Dior Cherie. The actress was snapped in Paris back in July on the set of the shoot which has once again been directed by Sofia Coppola. Now it's been made official with a preview of the ad unveiled to the press in New York on Wednesday (see screen grab above).

The TV campaign features a shot of a white swan, "subliminal advertising for my film [Black Swan]," Portman jokes. Referring to her much younger co-star, she added. "I felt like a big old cougar. He's, like, 20." Portman also stars in a series of print ads photographed by Tim Walker. Both campaigns are due to break in March.
