The song drops on July 21, but fans being the detectives they are think they've already uncovered who the song is about: Louis' girlfriend Eleanor Calder.
The fact that the couple broke up, but proceeded to get back together has people believing the "back to you" lyrics are pointing at their ~love story~.
In a press release posted on the Sony Music website, Louis revealed what the song was about, writing, "With this song we wanted to write something a little less soppy. It’s about that one person that no matter how hard you try, you keep coming back to. All your support has been amazing and I can’t wait for you to hear the track."
Now... this could well and truly be about Eleanor, but any Larries out there? 'Cos same, and we'll forever be in belief that any love song from Louis is about Harry Styles.
