Gossip Girl on set | Gossip Girl season four | Blake Lively | Leighton Meester
Gossip Girl on set | Gossip Girl season four | Katie Cassidy
We recently reported that there would be two new Gossip Girls on the scene, and after being wowed by Clemence Poesy in Paris, now it's the turn of former-Melrose Place star Katie Cassidy to steal the show.
The redhead is also currently filming alongside Leighton Meester in new film Monte Carlo, and while they may be the best of pals on set, Katie will be ruffling Blair's feathers playing her fellow Columbia student, as well as a potential love interest for Nate.
While so far we've only got the smallest of glimpses at Katie's on-set fashion, the oohs and ahhs are far from abating about Leighton and Blake's Upper East Side style. We've got serious outfit envy for their latest looks, especially Blair's ladylike leopard-print, and Blake's wow-worthy heels.
