“About 10 years ago I did myfirst shoot with Demiand those photos went everywhere and were viral before that was such the thing that it is today,” Shields, 39, tells PEOPLE.

“So when they asked me to shoot again, I, of course, said yes,” he says, “although this time was different. We had both grown a lot as artists and people, so I was very excited to see where the work would end up and the images that we would make.”

Shields explained that his girlfriend Evans, 25, met Lovato at their friend Charlotte Lawrence’s birthday party, which is when “the shoot idea was game-planned.”

“So of course, I wanted to shoot them together,” he adds.
