Katy Perry & Taylor Swift haven’t had the best relationship, exactly. Neither have actually explained why there’s so much drama, but Katy Perry just released her song “Swish Swish” which seems to be a clap back to Tay’s “Bad Blood.” “You’re a joker, And I’m a courtside killer queen,” is just one of the many feisty lines in Perry’s new jam. Apparently, the feud began when Katy stole 3 of Taylor’s dancers off her Red World Tour, & brought them along on her Prismatic Tour. Taylor released “Bad Blood” off her 1989 album, which was about a fellow female singer (ahem… Katy Perry). For years, I was never sure if we were friends or not,” she explained. “She would come up to me at awards shows and say something and walk away, and I would think ‘Are we friends, or did she just give me the harshes insult of my life?'” Swift then noted that the unnamed adversary did something “so horrible” that made them “straight-up enemies.” She got more specific: “She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me.” Perry later released a very cryptic Tweet. Nicki Minaj later entered the anti- Taylor club after she was snubbed by MTV VMA’s Video of the Year category. “If your video celebrates women with very slim bodies, you will be nominated for vid of the year,” she wrote vaguely- Again, she was talking about the video for “Bad Blood.” Katy came back today when she released her newest single “Swish Swish” & how convenient that Nicki Minaj joined her on the track? But that’s not all! Katy & Nicki are both on Calvin Harris’ upcoming album! Damn, yo! My head hurts!
