Can wives and mistresses ever be anything more than arch enemies? In "The Other Woman," Cameron Diaz, Kate Upton, and Leslie Mann star as women who figure out they're involved with the same man and plot to get revenge on him.

If the plots sounds a little familiar to you, then that's probably because it's very similar to "The First Wives Club" which is about 3 women who set out to get revenge against their individual ex-husbands.
