Leslie Mann and Game of Thrones star Nikolaj Coster-Waldau are in negotiations to star opposite Cameron Diaz in 20th Century Fox’s The Other Woman, The Hollywood Reporter said.

Julie Yorn is producing the comedy which sees a woman (Diaz) finding out that she is “the other woman” in an affair. She teams up with the wife (Mann) to get revenge on the cheating cad of a husband (Coster-Waldau).

Nick Cassavetes is directing the project, which was written by Melissa Stack and will shoot late spring/early summer in New York.

Mann recently starred in This Is 40 and has The Bling Ring with Emma Watson in the can.

Coster-Waldau is coming off of the hit horror movie Mama and will be seen with Tom Cruise in Universal’s sci-fi movie Oblivion. Game of Thrones, in which he plays the scheming Jaime Lannister, begins its new season March 31 on HBO. He is repped by WME and Jill Littman's Impression Entertainment.
