Michaels and Horan first got to know each other when she opened for the former One Direction singer during the European leg of his Flicker World Tour
in early spring 2018. She told Billboard
Horan is very easy to work with, and produces the goods too. "We always make fun of each other for a second, then he sings his heart out, and then he's like, 'Cool, I'll see you later,'" Michaels said. "And all of a sudden there's this magical vocal on this song, and he sounds like a sweet baby angel."
