Natalie Portman

She ruled a galaxy far away as Padme Amidala in the 'Star Wars' prequel trilogy and won an Oscar for her portrayal of suffering ballerina Nina Sayers in ‘Black Swan’ but after getting into the movie business as a teenager, Portman combined acting with education as she studied at Harvard University between 1999 and 2003 - obtaining a bachelor's degree in psychology.

She said: "I'm going to college. I don't care if it ruins my career. I'd rather be smart than a movie star."
