Sleeping with Other People stars Jason Sudeikis and Alison Brie as childhood sweethearts who meet again in adulthood and realize they both have trouble staying faithful in relationships. The two then decide to strike up a rigidly platonic relationship and have sex with other people – while potentially falling for one another.

Incidentally, Brie went public with her engagement to longtime boyfriend Dave Franco at the Sleeping with Other People screening by wearing her engagement ring.

Sleeping with Other People hits theaters Sept. 11.
