Blair Waldorf would no doubt have something to say about this.
Leighton Meester was seen in L.A. this week with locks a whole lot lighter than the darker 'do we've all come to know and love. But, unlike Angelina Jolie with her many Salt styles, and Kim Kardashian's attempt to fool us, the Gossip Girl star is definitely not sporting a wig.
Of course, only time will tell if this whole blond thing is simply for Leighton's new movie, Date Night, or just her way of changing it up a bit as she pursues pop stardom.
So what say you? Are you liking Meester's mane, or would the girls at Constance totally look down their snobby little noses at it?
