Jon Bon Jovi said this week he fully supports his 20-year-old son Jake Bongiovi getting engaged to his 19-year-old girlfriend "Stranger Things" star, Millie Bobby Brown.

"I don’t know if age matters," the 61-year-old told Andy Cohen on SiriusXM’s "Radio Andy" Tuesday. "If you find the right partner and you grow together, I think that would be my advice, really because growing together is wise."

Bon Jovi married his high school sweetheart Dorothea Hurley in 1989, when he was in his late 20s. 

The "Bed of Roses" singer added that he thinks "all of my kids have found the people they think they can grow together with, and we like them all."

The rocker said they "work hard" at their relationship, "but we enjoy each other, and we never fell for the trappings of what celebrity can do. 

"We've witnessed that happen over the years to people that were close to us and people that we knew from afar," he continued. "It's just what I do, it's not who I am. I write songs. I happen to be very good at performing them. That's it."
