Sigourney Weaver is in negotiations to join Tina Fey and Amy Pohler in the comedy Baby Mama for Universal Pictures, according to Variety.

The film, written and directed by Michael McCullers, centers on a single career woman (Fey) whose desire to have a child and keep her career leads her to hire a surrogate (Pohler). Weaver will play Chaffee Bicknell, owner and operator of the surrogate agency that Fey's character uses.

Shooting is scheduled to begin in May.
