Millie Bobby Brown and Jake Bongiovi are starting their parenthood journey.

The "Stranger Things" actress, 21, revealed in an Instagram post on Aug. 21 that she and her husband, 23, have adopted a "sweet baby girl" together.

"We are beyond excited to embark on this beautiful next chapter of parenthood in both peace and privacy," Brown and Bongiovi wrote in their joint post.

"And then there were 3," the couple added, with The Beatles song "Ob-La-Di, Ob-La-Da" accompanying the announcement. They did not share the child's name.

Brown and Bongiovi, who is the son of singer Jon Bon Jovi, first confirmed their relationship in 2021. In 2024, they tied the knot in a ceremony officiated by Brown's "Stranger Things" costar Matthew Modine.

On the "Call Her Daddy" podcast, Brown revealed she met Bongiovi after getting his number through a mutual friend and cold-calling him to ask if he was single. "We were friends for a while," she said. "We (would) text back and forth, and we watched shows on Zoom and stuff together."

Brown's baby announcement comes after she appeared on the "SmartLess" podcast in March and shared that she and Bongiovi hoped to start a large family together.

"Jake knows how important it is to me (to have children)," she said on the podcast. "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."

She continued, "Jake was like, 'We cannot do that until we get married.' So that was his thing, and my thing was, I really want a family. I really want a big family. I'm one of four. He's one of four. So it is definitely in our future."

Brown is preparing to close a major chapter in her life by saying goodbye to "Stranger Things," the show that made her famous with her role as Eleven. The Netflix phenomenon's final season is set to debut in November.
