Leighton Meester plays the role of Blair on the CW`s hot new show Gossip Girl. She plays an Upper East Side vixen, Blair Waldorf, who rules generally with manipulation, slight cruelty and a snobbishness that is incomparable, mostly because of her insecurities. However, in real life she is not as obsessed with proving herself to be the Queen of Mean. She grew up in Florida and moved to New York City to become a model when she was 11. Since then, she has pursued her acting career relentlessly and has been on dozens of television shows.
