A Timeline of Taylor Swift and Katy Perry's Feud, From Beginning to End

After years of feuding, the two superstars actually called a truce that stuck. Ahead of opening night for Swift's "Reputation" stadium tour in Glendale, AZ, Swift shared a video on her Instagram Story of an olive branch Perry sent to her dressing room. "So I just got to my dressing room and found this actual olive branch," she said in the clip. "This means so much to me." In addition to the gift, Perry also sent her "old friend" a handwritten note detailing how she wanted to clear the air.
