Earlier this year, Millie said of having a child, "Jake knows how important it is to me. Of course, I want to focus on really establishing myself as an actor and as a producer, but I also find it's so important to start a family for me, personally. It's a huge thing."

Millie Bobby Brown and Jake Bongiovi are officially parents. The couple announced Thursday in a joint Instagram post that they recently welcomed a baby girl through adoption.
