This latest batch of photos from the Gossip Girl set shows some familiar faces - including Chace Crawford, who we hadn't seen up until now - along with some new ones.

Yesterday was the first glimpse we've had of former Melrose Place star Katie Cassidy, who just signed on to play Nate's newest love interest, on the set of the hit show.

A few other familiar faces were spotted as well, including Amanda Setton (Penelope) and Alice Callahan (Columbia mean girl) - plus Leighton, Blake and Ed, of course.
