Blake Gets Lively At Letterman

Gossip Girl's Serena Van Der De La Woodsen herself, Blake Lively, showed up to Letterman's yesterday decidedly dressed down in jeans, low boots (which we're loving right now) and a cognac-colored leather jacket.

Since Serena usually dresses to the nines just to go to school, we were pretty surprised to see Blake going so casual!

Course, we know they're not the same person, but if the writer's strike doesn't end soon, we're gonna be jonesin' for some Gossip Girl!
