Months after their public split, the "We Are Never Ever Getting Back Together's" camp broadcasted that Taylor wrote Calvin's biggest hits song "This Is What You Came For" which he collaborated with Rihanna. This made the DJ felt bad and went to accuse his ex for making him look bad. Unfortunately, the "Style" singer was as furious and added that she could "bury" him like she did to Katy Perry.

However, Katy Perry denied any future music covering her conflict with Taylor Swift. "Well, that's not my question to answer - if it's about me. I think [my new album is] a very empowered record. There is no one thing that's calling out any one person," the "Hot n Cold" singer told Entertainment Weekly.
