Leighton Meester graces latest issue of GQ Magazine with her gorgeous sexy body. I first saw Leighton Meester on Season 4 of 24, two episodes of House, and then on Gossip Girl. I always thought Leighton Meester was purty and these pictures are simply more credence to that belief. In the Gossip Girl show, Blake Lively plays Serena, Leighton Meester plays Blair, Chace Crawford plays Nate, Penn Badgley plays Dan, Ed Westwick plays Chuck, Taylor Momsen plays Jenny and Jessica Szohr plays Vanessa. The show is based on the books but does not follow the same story line.
