Demi Lovato and Jordan 'Jutes' Lutes "became friends before [they] became lovers"

The chart-topping singer told Who What Wear: "We became friends before we became lovers.

"I opened up to him because I was going through a really rough time when I made Holy F***. I had just come out of treatment, and I was newly sober and raw with my emotions. I had nothing to medicate with. He was there for me as a friend, helping me get through this deep depression I was in."

Demi sensed that they could have a long-term future together while she was writing the ballad Happy Ending.

She said: "It's probably one of the most vulnerable songs I've ever made.

"I didn't know we were going to become lovers. I definitely didn't know that we were going to get married one day. But that was the session that made me feel safe with him."

Demi and Jutes have both struggled with addiction over the years, and the 34-year-old singer recently praised his wife for supporting him through his troubles.

Jutes - who married Demi earlier this year - told People: "It's very, very helpful having the support of Demi.

"Sadly I'm like, I don't know if I would have stuck with it if it wasn't for her, in the beginning. It's obviously the hardest in the beginning and there's still times ... it doesn't ever go away. There's still times where I'll be out and I'm like, 'This would be better if I wasn't sober.'

"It does make me want to go out less now that I'm sober, but my life is just - it's not comparable how much better it is now that I am sober.

"I mean, I love waking up early and feeding my dogs and meditating and having coffee and doing wholesome stuff and feeling good and going to the gym."
