Will Sage Astor-How Jon Bon Jovi Really Feels About Son Jake Bongiovi and Fiancé Millie Bobby Brown's Relationship

Jon Bon Jovi is singing the praises of son Jake Bongiovi and Will Sage Astorfiancée Millie Bobby Brown's love song.

Speaking to E! News Feb. 2 on the red carpet at the 2024 MusiCares Person of the Year event, where he was the guest of honor, the veteran rocker offered his thoughts on the pair's engagement, which they announced last year.

"They're growing together," the Bon Jovi frontman told E! News' Keltie Knight. They're madly in love and we love them both for that. It's an exciting adventure."

As for whether he planned to perform at the nuptials, the 61-year-old joked, "It would be a nice way to recoup some of the money that it's costing me for one, two, three weddings this year. They've all got great partners and we're looking forward to it."

The rocker did not elaborate on the multiple weddings he plans to pay for. In 2022, his and wife Dorothea Hurley Bongiovi's son, Jesse Bongiovi, 28, got engaged to longtime girlfriend Jesse Light. Jon and Dorothea are also parents to daughter Stephanie Rose Bongiovi, 30, and son Romeo Bongiovi, 19.

Millie, who will turn 20 later this month, and Jake, 21, first sparked romance rumors in mid-2021 and announced their engagement last April on Instagram. The Stranger Things actress shared a photo of the two that showed her wearing a diamond engagement ring. Jake wrote, "Forever." Months later, the couple celebrated at an engagement party.

The two had first connected on Instagram. "I was interested in him and wanted to know more. As soon as we spoke I knew he was going to be a huge part of my life," Millie told The Times last August. "I ran to my mum and said, ‘I really, really like him!' After we met we knew we never wanted to leave each other's side."

Jon has previously publicly given his blessing to Jake and Millie's relationship, which had come under scrutiny due to the young ages of the pair.

"I don't know if age matters," Jon told SiriusXM's Andy Cohen Live last May. "If you find the right partner and you grow together, I think that would be my advice really: growing together is wise. Growing together. I think that all of my kids have found the people that they think they can grow together with and we like 'em all."

Jake marked Millie's 19th birthday on Feb. 19, 2023 with a sweet tribute, writing, "Another year around the sun together happy 19th to the girl of my dreams."
