Liam Payne co-wrote the song with Ed Sheeran. The carrot-topped singer-songwriter has previously penned several songs for One Direction, including the Take Me Home
tracks "Little Things
" and "Over Again
," as well as "18
" from their Four
The collaboration was sparked by an unexpected call from Sheeran in the late summer of 2016. "I was in a gym in LA, and I got a call that said 'You have to get to London now,'" Payne recalled to Billboard
magazine. "And we had literally just gotten to L.A., so we U-turned straight back to London — which of course you do for Mr. Ed Sheeran, because I'd do anything for the man. We went in, sat around and discussed a bunch of things about life, and [the song] basically just came together."
