Shawn talked about their relationship in the 83-minute film, which follows his 2019 world tour.

The Monster singer talked about he met Camila, opening for Austin Mahone’s 2014 tour while she was a member of Fifth Harmony.

Their friendship eventually turned romantic last year.

“For the past, like, four years, just being friends and not being able to see each other very often to finally being able to be together, she was always there to look out for me as a human being,” Shawn said in the film.

He added: “She’s got my back, and I think that’s what your partner is for.”

The Mercy singer added that Camila, 23, inspired all of his songs – and that she was shocked when she found out.

“We were in New York and my song comes on the radio or something, and the fact comes up that it’s about her, and I’m like, ‘Yeah, it’s about you,'” he recalled.

He went on: “And I’m like, ‘Everything is about you. They’ve always been about you.’

“She goes, ‘What do you mean?’ I’m like, ‘They’re all about you. Like, every song I’ve ever wrote.’ And I’m, like, rhyming off the songs. I’m like, ‘Treat You Better,’ like, all these songs.

“And she’s like, ‘Oh, my God.’ She literally had no idea. This whole time I thought she, like, knew.”

He added that all of his songs have been inspired by her

Shawn and Camila were first romantically linked in July last year, when they were seen kissing in the sea in Miami.

They were later spotted walking hand-in-hand after the release of their racy music video for their new song Senorita.
