'Bad Moms' Trailer: Watch Mila Kunis, Kristen Bell and Kathryn Hahn Break All the Rules

Jada Pinkett Smith, Christina Applegate and Annie Mumolo also star opposite the trio in the comedy about being the perfect mom.

Mila Kunis, Kristen Bell and Kathryn Hahn are about to be moms gone wild.

The new trailer for the comedy Bad Moms explores the struggles of mastering motherhood as the trio sets out take down a clique of "perfect moms" led by Christina Applegate, Jada Pinkett Smith and Annie Mumolo.

Kunis stars as Amy, an overachieving mother of two who struggles to maintain a perfect home and career. After Amy's overworked and over-committed lifestyle causes her to snap at a school PTA meeting, she — along with Bell and Hahn's characters — decides to break free from overwhelming parenting rules. The women begin a new liberating, self-indulgent lifestyle of partying and even bringing unhealthy snacks to school events as they discover what it really means to be the perfect mom.

The Hangover writers Jon Lucas and Scott Moore directed and wrote the STX Entertainment film. Suzanne Todd and Bill Block are producing.

Bad Moms hits theaters July 29.
