The Taylor Swift vs Calvin Harris Feud Just Took Some Crazy Twists!

We're waking up to a whole lot of Taylor v Calvin developments - a LOT has gone down this morning and it all happened online before our very eyes.

It started when we got confirmation that producer extraordinaire Calvin Harris' new song with Rihanna was WRITTEN BY HIS EX, TAYLOR SWIFT. She wrote the lyrics under a pseudonym (while the two were still together, we assume).

Here's that song:

We were then rewarded with a flurry of revealing tweets from Calvin Harris, which started out nice and got steadily more confrontational and stroppy.

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

Note: the upside-down-smiley. WHAT DOES IT MEAN

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 🤔

Oh, that's what it means. 

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

SHOTS FIRED. Is that a reference to the Bad Blood song, supposedly aimed at Katy Perry? Then this kinda nice/could-be-sarcastic one to finish off: 

Please focus on the positive aspects of YOUR life because you've earned a great one
