15. Anne Hathaway
Anne Hathaway went from one serious role to another. She spent much of the Summer and Fall wearing a sexy Catwoman costume on the set of The Dark Knight Rises, though she broke from the action movie to promote and premiere One Day in August. In the Spring, Anne switched gears to film the musical Les Miserables after buzzing her hair for the part. In the middle of her packed acting schedule in November, Anne got engaged to boyfriend Adam Shulman, and the duo celebrated the news with an NYC bash in February. The excitement continues for Anne in July, when The Dark Knight Rises hits theaters.
