She had also spoken about the collaboration to the U.K.'s Sun earlier, as People reports, describing the song as a "cute acoustic love thing" on her ukelele. Trainor said it was unclear what would become of the song at this point, but the session was a succcess. 

"I was worried he'd just be a 20-year-old boy, so I walked in with a prepared voice and chorus. But he gave me very poetic, mature lyrics," she told The Sun. "I was like, 'Well, damn, Harry, you know what love is.'"
