Nylon magazine threw a bash for all the coolest kids last night at their Young Hollywood party at Amalia restaurant in New York.  Blake and Leighton (who just recently graced the Nylon cover) were there with the rest of the Gossip Girl gang, along with Jamie-Lynn Sigler and Zachary Levi from Chuck.  Fancy schmancy party in NYC-I swear sometimes these events practically look like a scene straight from the show!
