The cat is out of the bag! Taylor Swift and her team have gone public about the fact the she had written Calvin Harris’s hit ‘This is what you Came For” featuring Rihanna. Apparently Swift originally wanted to go unaccredited for the song, but now that it’s a huge hit she’s letting everyone know that she wrote the lyrics.

Calvin Harris took to his Twitter trying to explain himself saying “…she sings on it too and smashed it as usual”. However it only took a few minutes for things to get heated in the twitterverse. Harris went on to say that he was disappointed that “… her and her team would go so far out of their way to try and make ME look bad at this stage…”

Harris even got Katy Perry involved tweeting “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”

OUCH, Katy!
