"Ready For It"
The telling lyrics: "Younger than my exes, but he act like such a man"
Who it's supposed to be about: Joe Alwyn
Why? In addition to the lyrics, Swift made it crystal clear that the track was about Alwyn when she dropped hidden references to the actor in the accompanying music video for the song. Not only did she include his name in Chinese characters on one of the walls in the video, but she also included a quote that reads, "I Love You in Secret," which seems like a nod to their private relationship.
