Stranger Things' Millie Bobby Brown and her husband Jake Bongiovi have reportedly adopted their second child together.

Sources told People that the couple have welcomed a second child, just over a year after they announced they had adopted a baby girl.

Millie, 22, recently dropped a big hint that she and the 24-year-old actor had grown their family while out on a stroll with alpacas in the Dolomites mountain range in Italy.

Taking to Instagram on September 7, the Electric State actress shared a video, in which she held their daughter while Jake was seen walking alongside her with a baby carrier strapped to his chest. But a view of their newest family member was obscured.

In June, Millie shared her hopes of having a biological child in the future.

Speaking on 34-year-old media personality Kylie Kelce's Not Gonna Lie podcast, she said: "Always, always wanted to adopt.

"It was always part of my childhood dreams. Every time I was at home, and I was, you know, five, six years old, my parents were like, 'You had your baby dolls.' They were all adopted. I never had any of them myself. And I never pretended I was pregnant.

"It's not because I don't want that. Hopefully one day that's in my future."

Millie has been working towards a veterinary technician degree through online studies, but before then, she studied social work and was particularly fascinated by the courses on adoption.

The Enola Holmes 3 alum said: "Adoption is love, adoption is forever.

"I loved the aspect of adoption in my social work courses… so meaningful and important. And then I also learned what it, you know, speaking to, and reading a lot about being a birth mother and what that journey is.

"So for me, my husband and I took a lot of time to focus on what that story and what that journey looks like. And then we embarked it."

Millie and Jake announced they adopted a baby girl, whose godfather is her Stranger Things co-star Noah Schnapp, 21, in August 2025.

And this May, the Damsel cast member expressed how proud she is to be an adoptive mom and thinks all moms should be celebrated for how they started a family.

Millie told Extra: "We're all mothers, and no matter if we're adoptive mothers, birth mothers - a maternal figure. Everybody should be celebrated.

"Everybody is raising beautiful children, hopefully, and we're raising the next generation. So, of course, women should be celebrated in every way, and every day."
