It's unclear at the moment if this is a permanent cast addition or not - but Jessica Szohr is joining Gossip Girl in the role of Vanessa.

She'll portray Dan's (Penn Badgley) childhood best friend who moved away from home and returns to New York with a major crush on her former close pal. Unfortunately, she arrives home at a bad time because Dan is falling for Serena.

Szohr's previous TV credits include CSI and What About Brian.
