Mila Kunis is expecting her first child with fiance Ashton Kutcher later this year. And the actress rarely speaks about love.

Neither does Kutcher, who once said he is "going to do everything in my power to keep this relationship private." Their story, however, is well known. They began dating in 2012 and are now engaged. It has a fairytale edge to it.

According to Kunis, their relationship changed from being just 'good friends' to lovers. "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, was the proposal. I cried. I was a mess. Not to discredit any relationships in my past, but this relationship is different," says Kunis.

As for her birthing plan, Kunis says Kutcher will be in the delivery room when she gives birth to their baby, but the actress suggests he stay put in one particular position.
