So when Lovato called into a New Zealand radio station and asked if she hoped to marry the That '70's Show star soon, Lovato was as honest as ever.
"I am very, very in love with him. I think—we will probably wait a little bit longer, but—if he asked tomorrow I would say yes," Lovato said.
The gorgeous brunette confessed that at the beginning of their courtship they did get some grief for the 12-year age difference.
"I used to, definitely, whenever we were first starting to date about like five years ago, because I was 18 and he was 30, so people were definitely judgmental and even like my parents were kind of like, 'I don't know why someone his age is wanting to date someone so young.' After a while, everyone started to see that what we have is real and incredible and very special and we have been together ever since."
This past weekend Lovato credited Valderrama with helping her maintain a healthy body image.
"Learn to lurrrrrvveee yerrrrr currrrrvveees," she wrote on Instagram, alongside a photo of herself wearing a long sleeve pink and white romper and lying on her back with one of her legs propped up, showing off some fierce silver platform heels.
"I actually used to hate them...but then a special someone helped me learn how to love them...and he sure loves them....#squats #COOLFORTHESUMMER," she said.
Don't worry Lovatics, you won't have to wait too long for Lovato to walk down the aisle—but t it will be for gal pal Iggy Azalea.
The former Disney star will be a bridesmaid for the "Fancy" rapper, who got engaged to Lakers star Nick Young earlier this year.
And although she doesn't think Azalea will be a bridezilla, Lovato will be a loyal bridesmaid— even if that means she has to wear a "peach fluffy shoulder dress."
"I hope not, but it's for a day, so I will do whatever she wants," Lovato confessed.
