The 30 year-old actress couldn't contain her emotions when her future husband popped the question: "I cried. I was a mess. Not to discredit any relationships in my past, but this relationship is different."
Ashton Kutcher and Mila Kunis have got a busy future ahead of them.
The former 'That 70s Show' stars have to plan a wedding and prepare to welcome their first child into the world.
But Kunis recently recalled the moment the pair first became an item, which was a huge surprise to many people.
"All of a sudden, it wasn't the same. And I was really proud of myself for acknowledging that," Kunis told Marie Claire magazine.
Adding, "The best day of my life so far was the proposal. I cried. I was a mess. Not to discredit any relationships in my past, but this relationship is different."
In previous years Kunis admits, "I was really good at saying no," but now she told the magazine, "I decided I was just going to say yes to any opportunity that came, no matter how crazy. And it changed my life."
The usually private actress recently revealed that she wants a natural birth, but this doesn't mean she is unaware of what this process will entail, and for this reason Kutcher is banned from seeing anything below the waist.
"Two people are allowed in my delivery room: my doctor and my significant other," she said. "And [my future husband] is staying above the action. He'll be head to head. Not head to vag. 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," Kunis added.
Although it isn't known when her due day is, the 30 year-old will enjoy the rest of her pregnancy as it comes with certain advantages, such as having larger breasts.

"They're amazing! They've tripled in size. I was a 34A; now I'm a 36C. I'm so excited! I'm telling everyone I know, 'Go ahead, touch them!'" she admitted. "Without being an a--hole, I have to say, I love being pregnant."
