Tight-laced Kate Holbrook, a corner-office single CEO, hits the 37 mark and decides to have a baby. Faced with the disappointing news that she’s unable to bear children, she finds a surrogate mother, Angie, who is as carefree as Kate is strict. But Kate’s rigid plan goes haywire when Angie is forced to move in with her. A meeting of the minds it isn’t but the trial turns proves that family ties aren’t only found in bloodlines. Starring Tina Fey, Amy Poehler, Sigourney Weaver, Dax Shepard, and Greg Kinnear, Baby Mama debuts on April 18, 2008.
