EXCLUSIVE: 'Bad Moms' Cast Shares Tough Parenting Moments at Hollywood Premiere

Bad Moms reminds us that no parents are perfect, and stars like Christina Applegate opened up about their own "bad mom" moments on the red carpet of the film's Hollywood premiere.

"My daughter [5-year-old Sadie] yelled at me at today and I said, 'Hey man, you need to cut the attitude,' and she said, 'I don't have an attitude, dude!'" Applegate told ET. "Then I know I've done something wrong."

Mila Kunis is a soon-to-be mother of two, and she's learned to appreciate the little victories along her parenthood journey with husband Ashton Kutcher.

"Every night that we put Wyatt down, we high-five each other, and we're like, 'We did it! We kept her alive!'" Kunis joked. "And we're still in love. You high-five when you still like each other and you still like your kid at the end of the night, because sometimes they're the devil."

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.
