Blair Waldorf

Played by Leighton Meester

After making her television debut when she was 13 on "Law & Order," she got her breakout  role in 2004 with a recurring role as the Britney Spears-like singer Justine Chapin on the hit series "Entourage."

Raised in Marco Island, Florida, Meester became interested in acting when she appeared in a local production of "The Wizard of Oz."  When she was 11, she moved with her family to New York City and soon after began working as a model with Wilhemina, booking a Ralph Lauren campaign shot by Bruce Webber and working with then photographer Sophia Coppola. 

When not on the set, Meester passionately pursues her talent for music and creative writing.
