Another day, another round of photos from the New York set of Gossip Girl. On Tuesday, March 8, recurring guest star Michelle Trachtenberg was spotted filming scenes in Manhattan's Morningside Heights. But while she shot solo, the rest of cast was having a happy reunion on the Upper West Side. Joining the typical crew of Blake, Penn, Ed, Chace, Connor, and Jess, were former supporting stars Nan Zhang (Kati Farkas) and Nicole Fiscella (Isabel Coates) who haven't been seen since the first and second seasons. Welcome back to the set, girls!
