Their 15-year age difference made us think twice about whether the relationship would last or not, but it seems like the couple is still very much in love and they're sharing the secret to their happy relationship.
When asked what the secret to her happy relationship was, Demi replied: “I think that’s too big of a question to take on right now. I like to look at where I am in the present moment as being the highlight.”
One thing we do is in their future is more children. "Why not? Everything is possible! We have so much to live for, and obviously one of them is to have a child. I'm very enthusiastic about all the possibilities that living together gives us," said Demi.
"I'm an incurable optimist and a go-getter - it's in my nature to focus much more on what makes me happy than what makes me nervous."
Demi is already 46 so if she's planning on having more kids, she needs to really get on it! And hey, there's always adoption!
