Demi Lovato's been pretty busy with "Cool For the Summer" promo these days, but she's always got time to praise her man, actor Wilmer Valderrama.

The singer called in to Australian radio station ZM, and she opened up about her long-term relationship — which is apparently better than ever.

Demi acknowledged that people, including her family, were a little sketched out by their relationship at first. It's completely understandable, given the fact that folks look askance at most 30-year-olds who want to date a teenager. But the fact that they're still going strong — and how kind she says Wilmer is to her — has won over her loved ones. Plus, now that she's no longer barely-legal, the age difference is a less of a sticking point.

So, does she still find herself defending their pairing? "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 whileeveryone started to see that what we have is real and incredible and very special and we have been together ever since."

In fact, she's willing to make an honest man out of Wilmer, if he theoretically proposed.

"I am very, very in love with him. I think—we'll probably wait a little bit longer, but—if he asked tomorrow I would say yes," she told the hosts, who apparently think 22 is an age ripe enough to elicit a "why aren't you married yet?!"

Demi also discussed another impending side gig: Being a bridesmaid in Iggy Azalea's wedding.

"She's pretty chill, so I can't imagine that she'll be one of those brides that'll be super particular." When asked if she thinks Iggy will put her in some horrid "peach, fluffy-shouldered" dress, she replied, "I hope not — but it's her day, so I'll do whatever she wants." That's called true friendship.

Demi also dished on her role as Smurfette in the next Smurfs movie, and when we can expect her album ("this fall") — listen to the full chat here.
