Mila Kunis and Kristen Bell break all the parenting rules in the 'Bad Moms' trailer

STX Entertainment

"Bad Moms."

The writers of "The Hangover" are directing this summer comedy that follows Kristen Bell, Mila Kunis, and Kathryn Hahn as three moms who are over the conventional standards they're held to and decide to have some long-sought-after fun. 

"Bad Moms" also stars Christina Applegate and Jada Pinkett Smith as strict PTA moms who Bell, Kunis, and Hahn rebel against. 

If it's anything like "The Hangover" movies, expect some outlandish stunts and big laughs, and a lot of tickets sold. 

Watch the trailer below. The movie opens July 29.
