Anne Hathaway doesn't take any movie role lightly, and she's proved it once again by debuting a brand new hairstyle to match that of her character in the upcoming big-screen adaptation of Les Miserables!

Hathaway showed off her new look on Saturday evening while out in London with her fiance. Gone are her long, flowing, brunette locks, replaced by a super short, pixie hairstyle. Hathaway looked like she wasn't quite ready to show off the new look just yet, trying to cover up a bit -- but I think it looks just fabulous!

The reason for the new 'do is because Hathaway will be portraying Fantine in Les Mis, a prostitute who is having trouble providing and making a life for her daughter. One of the ways she is able to get some extra cash is by chopping off her hair. I love that Anne totally went for the real thing instead of just wearing a cropped wig! Rumor has it, she's also shedding some major pounds for the film, as her character falls ill with tuberculosis in the story. Talk about getting into character, huh!?

What do you think of Anne's new do?!
