The Other Woman is a 2014 Rom Com directed by Nick Cassavetes
This is the story of Carly Whitten played by Cameron Diaz. She is a New York City Attorney and JUST started dating Mark King, played by Nikolaj Coster-Waldau (Jamie Lannister from Game of Thrones). 
Here’s the thing about our boy Mark, we learn quickly that Carly is NOT the only person he is dating… naw… he actually already has a WIFE, Kate played by Leslie Mann, and perhaps many OTHER mistresses like Amber played by Kate Upton.
So Carly and Kate learn about each other and ultimately decide that Mark deserves payback. It’s essentially the grown up version of John Tucker Must Die. That’s your lead in for The Other Woman. A heads up, this movie got a LITTLE bit of flack critically however it KILLED it at the box office, 196.7 million dollars on a 40 million  budget.See omnystudio.com/listener for privacy information.
