Stranger Things actress Millie Bobby Brown says Jake Bongiovi is the one

Millie Bobby Brown has no doubt Jake Bongiovi is "the one".

The 19-year-old actress announced her engagement to Bongiovi, son of rock star Jon Bon Jovi, in April, and she knew "he was going to be a huge part of [her] life" the first time they met.

The Stranger Things star told the Sunday Times newspaper: "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.

"You can’t pinpoint why [someone is 'the one'], it’s just the feeling of knowing that that’s the person you want to spend the rest of your time with."

Brown didn't have any hesitation about accepting Bongiovi's proposal.

She shared: "I think so much of life is overthinking. The one thing that made clear sense to me was him. So I didn’t really have to do much thinking."

Brown also revealed that her engagement ring actually belonged to her own mother.

She said: "I’ve always loved that ring, it’s always stuck out to me, so she gave it to Jake. They were in cahoots about the whole proposal.

"I love that I can always keep a piece of my mum with me."

Earlier this month, Brown revealed that she's already started planning for her wedding day.

The actress admitted to feeling excited about her big day – but she's also keen to keep some aspects of her life out of the spotlight.

Asked what she can do to avoid outside attention, Brown told Women's Wear Daily: "I think probably drawing the curtains, just because there are only so many moments in life that you get only once. And to have everyone’s opinions and eyes looking at that just feels unnatural to me.

"So I feel it’s important to keep those things, those small precious moments in life, really close to your chest.

"I can say that the planning is going – it’s so fun and it’s such an exciting time in my life."
