Taylor Swift had Katy Perry, who was her long-time friend, rival, and fellow popstar, appear in her 'You Need to Calm Down' music video. This marked the end of their long-standing feud, which had started in 2012 over backup dancers. The two were seen embracing in the music video, dressed in food-themed costumes, showing that they had put their differences aside and were now on good terms. The appearance of Katy Perry in the music video was a pleasant surprise for both Swift and Perry fans, who were thrilled to see the two popstars reconcile.
