Charlize Theron, Jason Reitman and Diablo Cody — who collaborated on 2011’s “Young Adult” — are reteaming on an untitled project about motherhood.

Theron will star with Reitman directing from Cody’s script. The logline is under wraps.

“Young Adult” starred Theron as an alcoholic ghost writer who returned to her Minnesota hometown to restart her life, leading mostly to a series of embarrassments for all involved. Cody also produced and her screenplay was nominated for a Writers Guild Award.

“Young Adult” carried a $12 million budget and had a worldwide box office of $22 million for Paramount.

Reitman and Cody worked together on 2007’s “Juno,” with Cody winning an Oscar for best original screenplay. Reitman was nominated for a best director Oscar for “Juno” and “Up in the Air.”

Reitman produced 2009’s “Jennifer’s Body,” which was written by Cody. He also directed “Thank You for Smoking,” “Labor Day” and “Men, Women and Children.”

Theron was last seen in “Mad Max: Fury Road” and stars in “The Huntsman: Winter’s War.” WME represents Theron, Reitman and Cody.

The news was first reported by Deadline Hollywood. Reitman confirmed the story on his Twitter account with a photograph of himself with Cody.
