Ex-wife number two, Jackie (Michaela Watkins), is mother to adopted son Bert (Albert Tsai), and can pull Pete's strings with her special blend of neurotic, new-ageyness. And son Warren may have an erotic fixation on his dad's beautiful, young spouse. Daughter Hillary is not a fan of her new step-mom either, despite Kate's attempts to win her trust. Diane is quick to convey her withering disapproval of Kate's barely tapped maternal instincts.
Diane (Marcia Gay Harden) is ex-wife number one, an intense and overachieving former Olympic athlete and the mother of teenagers Hillary (Bailee Madison) and Warren (Ryan Scott Lee). But Kate is determined to make this work and become a part of the family no matter what. 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. They say the third time's the charm, and reformed party girl Kate is hoping that's true when she becomes the third wife of a slightly older man, Pete.
