Family man Ashton Kutcher confirmed the sex of his baby during a chat show appearance on Thursday.
The 38-year-old actor, who is married to stunner Mila Kunis, made the revelation on NBC's Late Night with Seth Meyers.
"We haven't told anyone. We're having a boy,' Ashton revealed in a high-pitched voice.
The hunky actor accidentally revealed he was having a son as he spoke to host Savannah Guthrie about his growing family.
The host, who is also pregnant, wanted to see how him and Mila were feeling about the arrival of baby number two after already having two-year-old cutie Wyatt.
"I thought the first one was exhausting in the beginning," the What Happens In Vegas actor said.
"I'm a little terrified to be honest!"
When asked how they were preparing little Wyatt for her new baby brother, he said: "We're OK. It's really exciting,"
"She, like, points to Mila and she's like 'baby brother' when she points to the belly 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 she knows that it's not going to be a plastic doll yet."
What's more impressive, is that Ashton revealed the fact that Wyatt can speak and understand English and Spanish and is working on her Russian.
Mila's grandparents only speak Russian so he studied the language for six months to better understand them.
Mila first told HELLO! magazine that the couple were expecting back in June.
Most people weren't surprised as both Ashton and Mila, 33, have been very vocal about their love of parenthood since they welcomed Wyatt in October 2014.
"You think you know how much you love another person, and then you have a child and you realise you didn’t know," Ashton previously told Ellen DeGeneres. "I think I really look at this as the greatest opportunity of my life.
He continued: "But the most amazing thing about having a baby is my partner, Mila. She's the greatest mum – I can't even! Like, I go to work every day and I come home and she's perfect."
They sound like the most perfect family on the planet!
