As an early Mother's Day gift, Dax Shepard and Ashton Kutcher surprised their wives Kristen Bell and Mila Kunis on Friday's Ellen DeGeneres Show.

The actresses had appeared to promote their new film Bad Moms, but once Shepard and Kutcher crashed the party, Ellen DeGeneres led the two couples in a game of "Never Have We Ever."

When DeGeneres asked whether or not any of the stars had thrown away something of their spouse's without permission, Shepard quickly owned up. "Honest to god, every time she goes out of town for more than 48 hours, I get rid of about 20 things. But luckily, her memory is so terrible, she has no idea," Shepard said. "Because, like her mother, she collects all kinds of things."
