Speaking about the collaboration Sykes said in December of 2016: "We wrote that song so unbelievably quickly. It all just poured out, and then we recorded it within the day. And that was that, and I was very, very happy with it and I released it in the UK. And then, I was like, 'This would sound just incredible as a duet'.

"I'd previously worked with Ariana on 'Almost is Never Enough'. Having that previous experience working with Ariana - and obviously, you know what an incredible voice she has. Everyone knows that. So, I just reached out. And I was like, 'You fancy singing this song?' She was like, 'Yeah. This is beautiful'.

"It was just a really nice moment. And she went in and killed it.

"I really wanted to include both versions because, from the reaction that I've had, people love both. And to leave one of them off the album would be unfair. So I'm glad they're both coming out."
