10 Things You Didn't Know About Taylor Swift

2. She Has Beef With Katy Perry Over Backup Dancers

There€™s a lot of €˜allegedly€™ to this story, but if you piece it all together, it makes sense. On 1989, her most recent album, Taylor talks trash about a fellow pop star in the song "Bad Blood." When asked about it in her recent Rolling Stone profile, we got a couple more hints; this mystery pop star hired some dancers away from Taylor€™s concert tour, and hired them for her own tour. Based on this timing (and an interview with one of the backup dancers), it€™s likely that Taylor€™s new 'frenemy' is Katy Perry. But since that interview, Taylor has declined to elaborate any further. There will be no Pop Princess Showdown €” instead, the public will have to satisfy itself with passive aggressive tweets.
