Say Farewell to Gossip Girl With a Look Back at the Cast's Cutest Snaps!

Tonight one of TV's most fashionable series comes to an end when Gossip Girl airs its final episode — check out pictures from the finale now. We'll have to wait and see if Chuck and Blair finally walk down the aisle, what happens between Serena and Dan, and the identity of Gossip Girl, but until then, we're taking a look back at some of the cast's best snaps over the past five years.

We've got on-set kisses, to industry parties and red-carpet affairs. Click through to see Blake Lively, Leighton Meester, Penn Badgley, and the rest of the Upper East Siders before we bid them a final farewell!

XOXO, PopSugar
