Mila Kunis has opened up about spending time with the love of her life, acting and preparing to become a mom.

The 30-year-old actress is surprisingly excited to begin a family with former costar and current fiancé Ashton Kutcher. What’s more surprising is the fact that Kunis actually shared her first kiss with Kutcher—when they were just friends—while filming an episode of That 70s Show. “My first real kiss ever was with him on the show,” she told W Magazine.

Kunis will remain eternally grateful for her time on That 70s Show, as it both jumpstarted her acting career at age 14 and introduced her to the love of her life. “Not only did it introduce me to my fiancé,” she said regarding her time on the show, “but I’m so grateful that all my mistakes are recorded for posterity. I went through puberty on television!” she laughed. “I grew five inches while I was on that show, and I had so many different eyebrow shapes!”

The actress maintains that she knows Kutcher, 36, is in it for the long haul because of what they experienced together as part of the cast. “I went through everything embarrassing that a girl can go through in front of my fiancé. There’s no question that he’s seen the worst. I find that comforting.”

As for her engagement, Mila hasn’t always loved the idea of marriage. What changed her mind? Falling in love with her best friend, of course. From the age of 12, I prepared my parents for no marriage. Then things changed—I found the love of my life.” But don’t expect the couple’s wedding photos to be plastered all over the tabloids. “Now my theory on weddings is: Don’t invite anyone. Do it privately and secretly. My parents are okay with that. They’re just excited that I said yes.”

While musing about the nature of the industry, she spoke affectionately of her husband-to-be. “We all get movie star crushes,” she said. “I’m marrying mine.”

The happy pair recently attended a mutual friend’s wedding in Italy.
