Mila Kunis is experiencing all the joys of pregnancy, but doesn't want fathers to think they know what a pregnant woman goes through.

Mila Kunis is taking a stand for pregnant women everywhere. The actress, who is expecting her first child with fiancé Ashton Kutcher, got into it with Jimmy Kimmel on Tuesday night, June 10, when he said he and his wife are expecting a baby.

"Oh, you both are having a baby?" she answered. "You and your wife are pregnant?"

With that, Kunis grabbed the microphone and went off on a rant about the dad's responsibilities.

"Hello, I'm Mila Kunis with a very special message for all you soon-to-be fathers: Stop saying, 'We're pregnant.' You're not pregnant," she said. "When you wake up and throw up is it because you're nurturing a human life? No. It's because you had too many shots of tequila. Do you know how many shots of tequila we had? None. Because we can't have shots of tequila. We can't have anything!"

Kunis' rant was obviously prepared, and was accompanied by dramatic music. She added that she, along with pregnant women everywhere, have "your little love goblin growing inside of all of us. All you did was roll over and fall asleep!"

Kunis and Kutcher finally confirmed their pregnancy last month, after plenty of speculation. She told Ellen DeGeneres that she is planning to have a natural birth.

"I'm crazy. I mean, I did this to myself — I might as well do it right," she explained. "I wanted this. It's like, no one made me do this. I did have a little help. Just a little bit."

There is no word on when Kunis is due, but she gave a hint that she may be pretty far along by telling DeGeneres, "We were actually able to hide it for a very long time."
