Leighton Meester: Derek Lam at NY Fashion Week!

Leighton Meester sits front row at the Derek Lam Spring 2011 fashion show during NY Fashion Week held at Lincoln Center’s The Stage on Sunday (September 12) in New York City.

The 24-year-old Gossip Girl star was sandwiched in between Harper’s Bazaar Editor-In-Chief Glenda Bailey and stylist Mary Alice Stephenson.

Leighton wasn’t the only celeb in attendance — Parks and Recreation actress Rashida Jones was also there!
