Katy Perry continues to stay quiet about who her new single, "Swish Swish," is about. While many have wondered if the 32-year-old singer's latest song, featuring Nicki Minaj, is about Taylor Swift, Jimmy Fallon asked her if the track "is about anyone we know." "I think it's a great anthem for people to use whenever someone's trying to hold you down or bully you," Perry replied, without naming names. "That's kind of what this record is about."
