Baby boy Kutcher will join big sister Wyatt, who arrived in October 2014. Kutcher was discussing his daughter's understanding of the new baby with Savannah Guthrie (who, incidentally, is also expecting her second child and just announced it's also a boy) when he let the gender slip.
"She points to Mila and she's like, 'baby brother' when she points to the belly," he said, "and then she points to dad and she goes, 'Beer,' so I think she gets there's something in the belly, but I don't quite think that she knows that it's not going to be a plastic doll yet."
One girl, one boy sounds just perfect for the pair, who met almost 20 years ago playing love interests on That '70s Show. But that doesn't mean the actors take their new role—as parents to two kids—lightly. "I'm a little terrified to be honest," Kutcher told Guthrie. "It's intensely scary."
Luckily, he and Kunis have some experience this time around. Because of that, Kutcher admits that he's not reading all the parenting books like he did for the first kid. "You have a recognition that they're pretty durable. You're not going to break them."
From what we've heard, Kutcher and Kunis are naturals at raising kids. "He has a constant desire to fix a problem," Kunis told Glamour in July. "He's always doing daddy hacks. He's so not a passive husband or father. He doesn't just go, 'I don't know' and throw his hands up in the air. He's like, 'We can fix it.'"
Kutcher also showed appreciation for his wife in an interview on The Ellen DeGeneres Show, calling Kunis "the greatest mom."
The couple married in a super-secret ceremony in July 2015 and have been just as down-to-earth about raising their kids. "The one topic of conversation we had even prior to ever having kids was always how do you raise a child to not be an a--hole?" Mila said on The Kyle & Jackie O Show. "And it's so important because we both came from pretty, pretty, solid poverty backgrounds and grew up very poor and are very much self-made and are very aware of what a dollar is worth."
