Leighton Meester in a Red Porsche

Leighton Meester in a Porsche on set of "The Room mate".



In the film Leighton plays Rebecca, a character who becomes obsessed with her new bunk-buddy Sara. Originally it was thought

that Leighton would play the character who gets terrorized by her roommate, but now it looks like the tables have turned and

the Gossip Girl star will be playing the bad girl (at least we think that’s what is going down).

The film also stars the drool-worthy Cam Gigandet along with Aly Michalka and Matt Lanter.
