Thanks to some of our lovely tipsters, we told you about Gossip Girl's Tuesday filming in Chelsea while it was in progress. Now we have the snaps, showing our favorite college bound crew in 20's garb, complete with pearls and sequin flapper dresses. The set jumped between The Gates and 25th street between 7th and 8th. This season's frequent guest Hilary Duff is still very much a part of the show, keeping us guessing about the love, trouble or filler she's going to play. XOXO.
