Gossip Girl Casting Chuck’s Mystery Girlfriend

Last week, The CW released some very early, brief but juicy Gossip Girl Season 4 spoilers.

“Season 4 will open with a radiant Serena and Blair enjoying their grand and romantic summer in Paris,” a press release from the network regarding the 2010-11 season reads. “Until Chuck mysteriously arrives in town with a new girlfriend and a new identity.”

Who is this new, mystery girlfriend? We obviously don’t know yet, but we’re going to find out.

This week, producers began the process of casting the recurring role of Eva, an utterly gorgeous female in her 20s or 30s who boasts a warm heart and an authentic French accent. Shooting begins in early July in both New York and Paris for the new season.

Any thoughts on who should play this new Gossip Girl character – or what her role will be?
