Taylor Swift and Selena Gomez

Taylor Swift's several love affairs have been the subject of widespread attention (thanks in part to her songs about her exes), but one steady presence in her life is that of Selena Gomez. Both singers followed similar trajectories to stardom, and have been supportive of each other through boyfriends, breakups, and "Bad Blood." After all, they've been pals since Selena was 13 and Taylor was 16. It seems the only threat to their bond is the ever-growing Swift Squad.
