Shop Celebrity Style: 'Gossip Girl' has started filming in NYC once again and we are getting all the secrets straight from the set. We spotted Clemence Poesy, aka Eva, getting cozy with 'Gossip Girl's' resident bad boy, Chuck Bass and dressed in a straight off the runway look. Clemence was seen strutting her stuff in a sheer Fendi number from the Spring 2010 Collection that definitely caught our attention and Chuck's as well.
