Momsen's portrayal of Jenny Humphrey on Gossip Girl is now in stark contrast with her hard core public persona as the front woman of her band The Pretty Reckless.
Naturally, her hairstyles have gone through a major evolution since she first hit the spotlight too, gradually becoming edgier - and blonder! - to suit her changing tastes. Here are some great photos of Taylor Momsen's hair.
