Leighton Meester: Colorful on

Hard at work on her latest project, Leighton Meester filmed scenes for “Life Partner” in Los Angeles, CA on Sunday (May 19).

Dressed in a colorful and funky ensemble of rainbow tights, denim shorts and matching suspenders, the “Gossip Girl” star joined in at The Long Beach Gay Pride Parade.

In the independent film, Leighton will play a “lesbian slacker” named Sasha. Sasha”s straight pal Paige, played by Gillian Jacobs, has made a vow not to get married until they both have the same rights.

However, things begin to change when Paige meets a young and charming doctor (Adam Brody) and their romance heats up. “Life Partner” is set for release in 2014.
