The “Livin’ on a Prayer” singer, 63, and his wife Dorothea have become grandparents for the first time after son Jake Bongiovi and daughter-in-law Millie Bobby Brown announced on Thursday, August 21 that they have become parents.

The Stranger Things actress, 21, and her husband, 23, confirmed in an Instagram post that they have welcomed a baby girl via adoption and are excited about the new adventures ahead.

“This summer, we welcomed our baby girl via adoption. We are so excited to begin this wonderful new chapter of parenthood in peace and privacy,” they wrote in a joint post.

Jake is Bon Jovi and Dorothea’s second son. They also have a daughter, Stephanie, 32, and sons, Jesse, 30, and Romeo, 21.

High school sweethearts, the singer and his wife eloped to Las Vegas in 1989 after nine years of dating. They welcomed Stephanie in 1993, Jesse two years later, and Jake in 2002. Romeo, their youngest, was born in 2004.

Speaking to PEOPLE magazine in 2020, Bon Jovi said the secret to their long and successful marriage is that they “really like each other” and “want to hang out together.”

“I’ve always said I’m really good at spotting potential. I have that gift,” Dorothea added.

Brown and Jake exchanged vows in a private ceremony in May 2024. The couple announced their engagement a year earlier.

Despite his young age, Bon Jovi has been a staunch supporter of the couple.

“I don’t know if age matters, as long as you find the right person and grow together,” Bon Jovi shared during an appearance on Andy Cohen’s Radio Andy on Sirius XM in May 2023.

He also shared some advice, saying: “Growing together is smart. I think all my kids have found people they think they can grow together with, and we like them all.”

In March 2025, Brown opened up about becoming a mother when she appeared on the Smartless podcast, saying her parents were young when she was born.

“Ever since I was a little girl, I told my mom, like a doll. I want to be a mom like she was to me,” she said, adding that Jake said they couldn’t start a family until they got married.

“And what I really want is a family. I really want a big family,” she continued.

“I’m one of four. He’s one of four. So that’s definitely in our future, but for me, I don’t see having my own kids, you know, as being any different than adopting,” she said.
