But today, the high profile pair have posted a photo of their son, Dimitri Portwood Kutcher, on Instagram. Suffice to say, it's not your standard selfie:
Yep: that's little Dimitri wearing his parents' faces on his shirt. "Yes, this is my son's outfit today," Ashton Kutcher captioned the photo, along with the hashtags #That70sShow and #KelsoAndJackieForever.
Kunis and Kutcher met on the set of That 70s Show in 1998, and welcomed their first child, daughter Wyatt, in 2014. Son Dimitri came along two years later, in 2016.
