The couple announced Thursday in a joint Instagram post that they recently welcomed a baby girl through adoption.
"My mom actually had her first child at 21, and my dad was 19. And you know, it's been my thing since before I met Jake," the Stranger Things actress told the SmartLess podcast at the time. "Since I was a baby, I told my mom, like, baby dolls. I wanted to be a mom just like the way my mom was to me."
