Leighton Meester shows off her taut tummy while sitting front row at the Proenza Schouler Spring 2011 fashion show during NY Fashion Week on Wednesday (September 15) in New York City.

The 24-year-old Gossip Girl actress wore a revealing Proenza Schouler top with a sexy skirt and skirt and bag. She finished off her look with Azzedine Alaia lace-up boots and a Fenton/Fallon ring. Looking good, Leight!
