What do you think of 'Gossip Girl' star Michelle Trachtenberg's new look? She's decided to go blonde.

Or at least, her character, Georgina Sparks, has decided to :)

For these pictures where Michelle is a blonde, she's filming on the 'Gossip Girl' set. I can't tell if it's a wig or she bleached her real hair, but below are pictures of Michelle as a brunette.

Which look do you prefer for Michelle: blonde or brunette?
