On their last album, 2015's "Made in the A.M.," One Direction included the song "Perfect." Styles and his bandmate Louis Tomlinson are among the writers on the track, and it has some pretty obvious references to Swift. The song's pre-chorus includes the lyrics, "When I first saw you from across the room / I could tell that you were curious," which acts as a second point of view to Swift's lyric, "I knew you were trouble when you walked in." Other lyrics allude to hiding from paparazzi in hotel rooms, and Styles ultimately sings, "And if you're looking for someone to write your breakup songs about / Then baby, I'm perfect."
