As awkward as this scenario might seem, the course is clear: When you find out your boyfriend is married and has another girlfriend on the side, you band together with the other ladies and get your revenge.
And that's exactly what happens in the upcoming comedy, The Other Woman, which is set to hit theaters on April 25. Cameron Diaz learns her "boyfriend" and primary lover, Nikolaj Coster-Waldau, is married to Leslie Mann and also has another mistress, Kate Upton.
Watch the clip above to see Mann and Diaz's amusing first meeting with Upton and unsurprisingly, Mann fawns over Upton's "amazing" scent.
The 21-year-old model recently gushed to E! News about teaming up with the actresses on the Nick Cassavetes-directed flick.
"I was on set with Cameron [Diaz] and Leslie [Mann] and they were the most inspirational and amazing women I had the honor to work with," the blond beauty revealed in October. "They were really helpful in my experience with the movie, and I really appreciated all of their advice and all of their encouragement throughout the movie set."
And while the cast certainly looked like they had a lot of fun while they were filming, the Sports Illustrated star admitted she learned a great deal from her talented costars.
"You know what? They helped me in every way," she said. "My life, and, you know, how to feel confident in creating the role and being the character."
