In an interview with Howard Stern, Ashton Kutcher remembers the first kisses he ever shared with his wife Mila Kunis on and off screen. Together, the couple starred in That ‘70s Show (he was 19 and she was 14) years before they’d ever date, much less get married!

“I did her chemistry homework for her,” he said to Howard. “I think I was her first kiss on the show. We have our first kiss like memorialized on the TV show. It was really weird. I was like, ‘Isn’t this illegal?’ It was really awkward. She was 14! She was like my little sister.”

Despite that Mila previously told Howard she wasn’t attracted to Ashton until years later, he has a different opinion:

“She has a journal, like a diary of when she was a kid that she wrote … she thought I was cute,” he said. “At first I think she thought that I was good looking. Shortly thereafter, I was just annoying to her because I was like a big brother.”

A second kiss happened in real life, and in many ways it was their FIRST kiss. It was a party.

“She’s like, ‘You’re not ready to be in a relationship’ and I’m like, ‘I”m not ready to be a in a relationship,’” he admitted. “It was funny because I’d just done this movie called No Strings Attached and she just did a movie called Friends with Benefits and we legitimately lived out our movies, which was virtually the same movie.”
