BREAKING: Calvin Just Slammed Taylor On Social Media And Revealed 4 Juicy Details

If you've been paying any attention to Calvin Harris and Taylor Swift's breakup drama, then you're going to LOVE this. Calvin just tweeted some pretty nasty things about Taylor, after it was revealed that SHE actually wrote his song, "This Is What You Came For." Get out the popcorn, this is going to be good! 

Calvin Harris is NOT a happy camper these days. It was just revealed that Taylor Swift wrote his song "This is What You Came For" and is mad that she didn't get any credit for it.

The songstress used the pseudonym Nils Sjoberg. She apparently wrote the song, and sent a voice memo of it to Calvin.

At first, Calvin tweeted about Taylor being a part of the song, and confessing that she even sings on it as well. 

All seemed fine and dandy.

But things quickly turned sour as he started hating on Taylor, again through Twitter. He was confused as to why this was making the news, saying that Taylor wanted this to be private, hence the pseudonym. He even fired a shot at her new relationship with Tom Hiddleston.

He even took a dig at Taylor's feud with Katy Perry, saying "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".

This isn't the first time Calvin has spoken out about this SUPER dramatic breakup with Taylor. He even implied that Taylor broke up with him to be with Tom.

But now the tables have turned and Taylor is saying they broke up because she received zero credit for the song...

I guess we'll have to wait and see if Taylor fires back or not. COMMENT and tell us what you think about all this drama!
