Mila Kunis is coming clean about her biggest "parenting fail" to date.
The Friends With Benefits star, 38, is a proud mom-of-two to seven-year-old daughter Wyatt and four-year-old son Dimitri, whom she shares with husband Ashton Kutcher.
Appearing on the Mom Confessions segment of The Ellen Show, Mila said that she considered her biggest "parenting fail" to be the time she told her daughter to retaliate against a school bully.
"There was a little kid in my kid's preschool that wasn't very kind and pushed my daughter," Kunis said.
Watch Mila Kunis come clean about her parenting faux pas:
She added: "My daughter came back and was like, 'Such and such little kiddo pushed me.' And I instinctually said, 'Did you push her back?' And my daughter's like, 'No!'"
Mila said she then told her daughter to "push her back next time and say no thank you and walk away."
She said that after she shared the advice she turned around to see her husband Ashton, 43, shaking his head in disagreement and mouthing the word, "'No!'"
However, she said she continued to advise her daughter. "You stand up for yourself and say no thank you," she recalled saying.

She went on: "Don't push her off of a ladder, off of a swing or off of a slide, but on the ground, even-steven, you push her back."
"I'd say that that's a parenting fail," she added in hindsight.
Elsewhere in the truth-telling segment, the That '70s Show star explained how her daughter reminds her of herself.
"My daughter is me. She is independent and feisty and wonderfully smart and it is an incredible trait to have as an adult but really hard to wrangle as a kid," she shared.
"She has a million answers to one question and she's not wrong."

Earlier this year, Mila and Ashton made headlines for their parenting choices after admitting that they only bathe their children when they are visibly dirty.
The couple opened up about their unusual parenting habits for their two children during an interview on the Armchair Expert podcast.
Bathing was brought up when co-hosts Dax Shepard and Monica Padman started discussing how frequently they take a shower, and it was then that Shepard, 46, said that Padman, 33, "should not be getting rid of the natural oil on your skin with a bar of soap every day."
In response to this, Mila and Ashton agreed.

"I can't believe I am in the minority here of washing my whole body in the shower. Who taught you to not wash?" Padman asked, as Kunis replied: "I didn't have hot water growing up as a child, so I didn't shower much anyway."
"But when I had children, I also didn't wash them every day," the Bad Moms actress said. "I wasn't that parent that bathed my newborns - ever."
Shepard said that he and his wife Kristen Bell bathed their children Lincoln, eight, and Delta, six, every day as "part of a nighttime routine," however, they stopped when they got older.
"That's how we feel about our children," Kunis said.
Kutcher added: "Now, here's the thing: If you can see the dirt on them, clean them. Otherwise, there's no point."
