Pregnant Mila Kunis shared her fears of feeling labor pains.

Luckily, Mila's doctor gave her fiancé a go to come with her in the delivery room. But she shared that it won't be easy for Ashton since he is required to keep his head "above the action".

"Two people are allowed in my delivery room. My doctor and my significant other. And he is staying above the action," she told Marie Claire magazine.

"He'll be head to head... unless he wants to risk his life and see. But I wouldn't if I were him. I highly doubt he wants to see that being ripped apart and shredded. Because it will be shredded. It's just a matter of how badly."

Mila also shared how her relationship with Ashton sprung out of a good friendship.

"One day, it just changed," she recalled. "All of a sudden, it wasn't the same. And I was really proud of myself for acknowledging that."

"The best day of my life so far," she said of the February proposal. "I cried. I was a mess. Not to discredit any relationships in my past, but this relationship is different."
