Soon after news broke that Taylor Swift penned the lyrics to Calvin Harris and Rihanna's smash hit, "This is What You Came For," the interwebs (unsurprisingly) went bonkers. But it also pushed the Scottish DJ to tell his side of the story on Twitter.

"And she sings on a little bit of it too," Calvin started his Twitter monologue. "Amazing lyric writer and she smashed it as usual."

While he gave his ex-girlfriend props, things quickly turned sour as he started to explain that Taylor did write the lyrics but didn't want to be credited, which is why Nils Sjoberg was born.

He then called out Taylor and her team for putting this into the forefront and pointed out that she should focus on her new boyfriend, Tom Hiddleston, and not Calvin.

I wrote the music, produced the song, arranged it and cut the vocals though. And initially she wanted it kept secret, hence the pseudonym

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 🤔

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

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
