'Bad Moms' co-stars Bell and Kunis and their respective husbands shared secrets in a couples version of the game on Friday's 'Ellen DeGeneres Show.'

Bad Moms costars Kristen Bell and Mila Kunis appeared on The Ellen DeGeneres Show Friday for a special Mother's Day episode.

Their respective husbands, Dax Shepard and Ashton Kutcher, surprised them with a pre-taped message. "We put babies in you," said Kutcher, as the two thanked them for being good mothers. "Thanks for being good earners too," said Shepard. Then the two men walked out with flowers for their wives, surprising them by joining them on stage for a game of "Never Have I Ever," but a couples version.

Both couples started out with the same answers: they've hooked up with their spouses on set, used each other's toothbrushes and have never gone to a nude beach. "Sorry guys, this Hollywood lifestyle is not as exciting as it's advertised," said Shepard about the nude beach response.

Things got tricky, though, when the wives and husbands had different answers. When asked if they've ever been in handcuffs, Shepard said yes and Bell said no. "He's talking about another partner, Ellen!" Bell exclaimed. "No, no I'm talking about the police," explained Shepard, misunderstanding the sexual innuendo in the question.

DeGeneres also spoke with the ladies about whether or not they want more children. (Kunis does, Bell doesn't.)

"Are you trying?" DeGeneres asked Kunis. "Like am I having sex, Ellen?" responded Kunis. Then things spiraled as DeGeneres joked she wants to know how often Kunis and Kutcher are having sex and Bell jumped in with her own questions about how good the sex is. DeGeneres said that was a "great question" and said she'd "imagine it's good."

"I feel like he would be a generous lover," added Bell.
