Calvin Harris Slams Taylor Swift on Twitter After It's Revealed She Wrote 'This Is What You Came For': 'You Need Someone New to Try and Bury ... I'm Not That Guy'

After news broke Wednesday Taylor Swift wrote her ex-boyfriend Calvin Harris’ hit, “This Is What You Came For,” the producer and deejay took to Twitter to tell his side of the story.

“And she sings on a little bit of it too. Amazing lyrics writer and she smashed it as usual,” he wrote on Twitter. “I wrote the music, produced the song, arranged it and cut the vocals though. And initially she wanted it kept secret, hence the pseudonym.”

Harris continued, saying it is “hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though.”

Weeks after the pair’s split was revealed in June, Swift stepped out with actor Tom Hiddleston, and the new couple has been traveling around the world in the last few weeks.

“I figure if you’re happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do,” Harris continued on Twitter. “I know you’re off tour and you need someone new to try and bury like Katy ETC but I’m not that guy, sorry. I won’t allow it.”

Swift has long been rumored to be in a feud with fellow pop star Katy Perry, and her song “Bad Blood” is reportedly about the “Roar” singer. (Neither star has officially commented on the rumors).

“Please focus on the positive aspects of YOUR life because you’ve earned a great one. God bless everyone have a beautiful day,” Harris wrote.
