WATCH: Natalie Portman is 'The Other Woman'

Is Natalie Portman a home-wrecker? She is in her new movie 'The Other Woman' and ET has a sneak peek at the trailer.

In the film, Portman plays a woman who has an affair with her boss who she then marries. Her character is then thrust into motherhood as her new husband, played by Scott Cohen, has a young son and she soon gets pregnant. 'The Other Woman' is getting a Video on Demand release by IFC on January 1 and limited theatrical release February 4.

Portman's life seems to be imitating her art as she recently announced that she is engaged to her 'Black Swan' choreographer Benjamin Millepied and they're expecting a baby!
