Katy Perry took to Twitter to throw in her two cents about the recent dispute between Calvin Harris and Taylor Swift, which took a turn for the worse after Harris tweeted about Swift yesterday.

In his tweets, Harris refers to Swift's role in helping write his song with Rhianna titled 'This Is What You Came For.' He then starts to tweet about how "hurtful" Swift is being.

And she sings on a little bit of it too ?
Amazing lyric writer and she smashed it as usual https://t.co/vW3yGOIJit

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
