Mothers are getting The Hangover treatment in the upcoming comedy Bad Moms, and the cast tells ET that while the movie is exaggerated, it's not that far off from real life.

"I'm very young as a mother," Mila Kunis notes. "I only have just 16 or 17 months, so I'm very new at this, but I would say 100 percent I have all the characters within me. Every mother does, and if they say they don't, then they are that person."

In the film, Kunis plays Amy Mitchell, a mom whose family is her life, but when her man-child husband, high-maintenance kids and the condescending alpha moms at her kids' school push her too far, she finally snaps. Going from good Amy to bad Amy, she teams up with two other misfit moms (Kathryn Hahn and Kristen Bell) to get a jolt of freedom that shakes up her life and might even make her a better mother.

While the comedy is about moms and family, moviegoers should know that it is definitely not a family flick.

"You guys think it's like a myth, but we do have dirtier mouths than men," Christina Applegate told ET. "The subject matter is far more offensive."
