Carly (Cameron Diaz) discovers that her boyfriend Mark (Nikolaj Coster-Waldau) has a wife when she shows up at his house to surprise him. Just as she is about to forget about the whole thing, Mark's wife Kate (Leslie Mann) show up at her office and the two begin a very unlikely friendship.
Slow starting, a third of the movie chronicles the beginning of Carly and Kate's friendship, and isn't until when they start plotting their revenge that the movie picks up pace. With a predictable ending, the thrill is getting to that point, but 'The Other Woman' fails to induce laughs in a natural way. Scenarios are forced and some of the jokes are cringe-worthy.
