London: Actress Leighton Meester and her actor-boyfriend Adam Brody are set to co-star in new comedy `Life Partners`.
Though the real life couple is in the lead cast, but they won`t be playing on-screen couples. Meester, seen in `Gossip Girl`, will play a lesbian.
The other cast of the film includes Gillian Jacobs and Gabourey Sidibe.
The couple was seen together in romantic comedy `The Oranges`, where Meester played the role of Nina Ostroff and Brody was seen as Toby Walling.
