BREAKING: Nicki Minaj, whose clever and sassy commentary makes American Idol bearable, has signed on to star with Cameron Diaz in The Other Woman, the pic that Nick Cassavetes is directing for Fox. Diaz plays a woman who realizes she is not her boyfriend’s primary lover, and teams up with the man’s wife to plot revenge. Game Of Thrones‘ Nikolaj Coster-Waldau plays the cad, and Leslie Mann, Kate Upton and Chicago Fire‘s Taylor Kinney also star. Minaj makes her screen-starring debut, playing the larger-than-life assistant to Diaz’s lawyer character. The assistant is opinionated and sharp and brutally honest, and we know Minaj can handle that. The film shoots in New York in May. She was repped on the deal by Gee Roberson, Brian Sher and attorney Kenny Meiselas.
