Hathaway was born on Nov. 12, 1982.
"The Princess Diaries" was her big screen debut. It was a huge hit with kids, but after making one sequel, Hathaway shifted her focus to more adult roles.
She was nominated for an Oscar for "Rachel Getting Married," and vamped it up as Catwoman in latest Batman movie.
For her next role, she'll play the ill-fated Fantine in "Les Miserables," which is due to come out this December.
