Trophy Wife (2013)

The third time's the charm, they say, and reformed party girl Kate is hoping that's true when she becomes the third wife of a slightly older man, Pete. They fell into each others' arms (literally) at a karaoke bar, and flash forward a year later, Kate finds herself with an instafamily complete with three stepchildren and two ex-wives. But Kate is determined to make this work and become a part of the family no matter what.
