When we first heard last week that Leighton Meester was making a movie with IRL boyfriend Adam Brody, we were like “Aww, cuuuuuute!” After all, nothing fulfills our creepy, voyeuristic tendencies quite like seeing a real life couple kiss (or whatever!) onscreen. But, um, that’s not what’s happening in the currently-in-production film Life Partners, according to Deadline’s inside scoop.

The comedy will be the first for Director/Co-Writer Susanna Fogel. And although we saw set pictures of the flick, which co-stars Community’s Gillian Jacobs, we had no idea what the movie was actually about until now. But here’s the story: “The comedy is about a codependent friendship between two very different girls.”

Okay, sounds like Gossip Girl’s Blair Waldorf (Leighton) and Serena van der Woodsen (Blake Lively) so far... But that’s where the similarities to Leighton’s previous job end.

Gillian plays a type-A girl named Paige whose best friend Sasha (Leighton) is a lesbian slacker. Not exactly the Upper East Side society girl Leigh portrayed for six seasons on GG...

The rest of the premise goes like this: “Paige has vowed that she won’t get married until Sasha has the same legal right and that works out fine until Paige meets Tim (Adam Brody), a young and charming doctor.” Yeah, cute boys have a way of turning our resolution upside down. So, what happens? What you’d expect.

“As a crucial vote on gay marriage approaches, the threesome struggle with issues of love, friendship, and loyalty.” In moments like this, we have to ask the age-old question: What Would Seth Cohen Do?
