The mom-to-be appeared on Ellen DeGeneres' Mother's Day special on Friday (May 9) and opened up about that giant rock on her left hand and her first child with fiancé Ashton Kutcher.
The "Jupiter Ascending" actress revealed that for "a very long time" she was able to hide not only her baby bump from the public but her engagement as well.
"I think everyone assumed we've been engaged so long that I was wearing the ring in public for two months and nobody commented on it in a single photograph," Mila said. "It was amazing."
Mila wouldn't divulge the baby's gender and due date, saying only it would arrive "some time this year," but was more than willing to talk about her unusual cravings, which have been stinking up her whole house.
"I'm very stereotypical. I eat sauerkraut all day long," Kunis said. "Here's the truth: This is the worst craving to have because sauerkraut smells and so every time you open up a jar, it just reeks in the whole kitchen. ... It's not like ice cream where everything smells lovely."
And if you were wondering whether Ashton has been helpful during her pregnancy -- he has. The actor scored major points with his bride-to-be -- who's planning an all-natural birth -- by pre-stocking their fridge with all different kinds of foods that Mila may or may not crave during her pregnancy.
"He assumed that I was gonna have goofy cravings, so he stocked our secondary fridge with weird food," she exlpained. "Just like pickles and sauerkraut or, like, anchovies and ice creams, just in case at one point during this pregnancy I'd be like, 'I really want something.' And it happened last week. I was like, 'Oh my God, I need a pickle!' It was just the weirdest thing, like I needed this pickle. And he was like, 'Hold on a second,' and disappeared in the backyard and came back with the most amazing dill pickle of all time."
