According to E! News, Kunis has brought the couple's first baby boy into the world. No details quite yet on Kutcher number four's name.
On Wednesday, June 15 the couple announced they were expecting their second child. The new baby is the lucky little brother to the couple's first child, 2-year-old Wyatt Isabelle.
In October, 38-year-old Kutcher made an appearance on Late Night With Seth Meyers, where he explained why he was hoping for another little girl.
"I was actually hoping for a girl," he said. "Because first of all — our first girl is unbelievable. But also I figured if we had a girl second, [Mila] might give me one more shot at having a boy, and now I don’t know. It's even money — she might cut me off. I want, like, 12 of them."
The couple first became acquainted when Kunis was only 15 years old on the set of hit series That '70s Show. While the show ran from 1998-2006, their relationship didn't take off until they began dating in 2012.
All our best wishes to the growing family.
