Stranger Things actress Millie Bobby Brown, 21, has adopted a child with Jon Bon Jovi’s son.

The British star announced on social media that she and her husband Jake Bongiovi had adopted a “sweet baby girl” and was “beyond excited” to become a parent.

Brown, who rose to fame playing Eleven in the series Stranger Things, married Bongiovi, the 23-year-old son of a rock star, at a ceremony in Italy last year.

“This summer, we welcomed our sweet baby girl through adoption,” Brown wrote in a post on Instagram.

“We are beyond excited to embark on this beautiful next chapter of parenthood in both peace and privacy.

“And then there were three. Love, Millie and Jake Bongiovi.”
