Taking to his website A+, the proud dad shared the name and a photo of that ’70s baby.
He wrote: "Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy.
"Can you guess which one is ours, or does it really matter? All babies are cute."
He then proceeded to add a selection of baby pictures, shrouding little Wyatt in privacy for the time being.

Well played, Ashton. Well played. Although, in all seriousness, we think it's Baby Number 4 - she's a dead ringer for Mila!
The name Wyatt is traditionally a boy's name, meaning "brave and strong", which makes it an utterly individual choice for Ashton and Mila's first child together.
Ashton and Mila became engaged in February this year, so it remains to be seen if they'll wait until little Wyatt is old enough to toddle down the aisle in bridesmaid gear for their wedding day.
