Blake Lively, Leighton Meester, Penn Badgley Gossip Girl on set tights blonde bruenette boots

Katie Cassidy was snapped on the set of Gossip Girl in New York City yesterday, and we hate to diss Blake Lively, but Katie is definitely the hottest blonde on the show! Well, aside from Taylor Momsen, of course...

P.S. Is it just us, or does Katie's character get waaaay better clothes than Blair Waldorf?
