Leslie Mann is in talks to join romantic comedy The Other Woman.
The This Is Forty star and Mama actor Nikolaj Coster-Waldau are reportedly in negotiations to join the film, said The Hollywood Reporter.
Cameron Diaz is already attached to play a woman, who soon finds out that she is the other woman in an affair.
She decides to team up with the wife - tipped to be Leslie - in order to get revenge on the cheating husband (Nikolaj).
The Other Woman will be directed by Nick Cassavetes.
Leslie is best known for her screen collaborations with husband Judd Apatow on This Is Forty, Knocked Up, The 40-Year-Old Virgin and Funny People.
The 40-year-old actress will next play Emma Watson's screen mum in The Bling Ring.
