See Inside Millie Bobby Brown and Jake Bongiovi's Engagement Party

As for how Jake's dad Jon Bon Jovi feels about them getting engaged at a young age?

"I don't know if age matters," he said on the May 2 episode of SiriusXM's Andy Cohen Live. "If you find the right partner and you grow together—I think that would be my advice really is growing together is wise. Growing together. And so, I think that all of my kids have found the people that they think they can grow together with and we like 'em all."

And the rocker had nothing but praise for the actress. "Millie's wonderful," he added. "Her whole family is great, really great. Jake is very, very happy."

Over the years, Millie and Jake—who first sparked romance rumors in 2021 and made their red carpet debut as a couple the following year—have given fans glimpses into their relationship on social media, with her recently sharing a tribute in honor of his birthday in May.

"This sums us up," she wrote alongside a series of photos of the pair. "In bliss, exploring together. I am eternally holding your hand. Happy birthday fiancé. I love you."
