Shawn and Camila wrote this song together backstage at one of Taylor Swift's 1989 shows. The song is amazing and sounds great. This makes us excited for Shawn Mendes new album Handwritten Revisited which is set to be released this Friday and also makes us excited for our girls Fifth Harmony's new album. We know it's going to be amazing! #5H2
