Jennifer Aniston and Jason Bateman have signed on to star in a “fertility-themed comedy,” Variety reports.

“The Baster” revolves around Wally (Bateman), a neurotic and insecure man who finds out his best friend Kassie (Aniston) plans to get pregnant through artificial insemination. Unbeknownst to Kassie, he replaces the donor’s deposit with his own, making him the true — and secret — father of the child.

Will Speck and Josh Gordon, who co-helmed 2007’s “Blades of Glory,” will direct from a screenplay by Allan Loeb (”21″). The movie is based on a short story by Jeffrey Eugenides that was first published in The New Yorker.

The movie is slated to begin shooting in the spring.

Aniston can currently be seen in the ensemble rom-com “He’s Just Not That Into You,” which opened in theatres Friday.

Bateman will hit the big screen in April in the political drama “State of Play,” which also stars Rachel McAdams, Russell Crowe, Ben Affleck and Helen Mirren.
