Ed Westwick, Leighton Meester, Matthew Settle and the rest of the Gossip Girl cast looked positively fabulous at the CW Network's Upfronts at Lincoln Center on Tuesday in New York City.

They certainly make a cute couple. Click to enlarge the photos of your favorite Gossip Girl stars from last night's Upfronts ...
