Mila Kunis admits that she told her parents she would never marry

Mila Kunis has revealed that she never thought she would marry until she fell in love with Ashton Kutcher.

The 30-year-old actress said: "I never wanted to get married. From the age of 12, I prepared my parents for no marriage."

Her feelings changed, however: "I found the love of my life. 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."

Mila and Ashton began dating in 2012, and became engaged early in 2014 before later announcing that they were also expecting their first child together.

The pair first met on the set of That 70s Show, and Mila also revealed she shared her first smooch with Ashton.

Speaking to W magazine, Mila said: "My first real kiss ever was with him on the show. And when That '70s Show had a prom, my date for the prom turned out to be my fiancé. We can honestly say that we went to prom together."

She also admitted that the comedy show holds a special place in her heart and not only because she met Ashton on set.

"Not only did it introduce me to my fiancé, but I'm so grateful that all my mistakes are recorded for posterity," she explained. "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."

Mila recently opened up on falling in love with a friend. She said: One day, it just changed. All of a sudden, it wasn't the same. And I was really proud of myself for acknowledging that."

Speaking to Marie Claire of the proposal, Mila said: "The best day of my life so far was the proposal. I cried. I was a mess."

The Black Swan star also admitted that she has already made plans for the baby's delivery, and that there will only be two people in the room - Ashton and the doctor.

"Two people are allowed in my delivery room," she shared. "My doctor and my significant other. And he is staying above the action... Unless he wants to risk his life and see."
