Looks like things are getting ugly between Taylor Swift and her latest ex-boyfriend, Calvin Harris!
On Wednesday, a rep for the “Blank Space” singer confirmed that Swift co-wrote Rihanna and Harris’ hit song “This Is What You Came For” under the pseudonym Nils Sjoberg, according to People.
Harris then took to Twitter upon the release of the news. First, the DJ praised Swift:
And she sings on a little bit of it too 🙃
Amazing lyric writer and she smashed it as usual https://t.co/vW3yGOIJit— Calvin Harris (@CalvinHarris) July 13, 2016
But then Harris decided to clarify his part in making the song:
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 🤔

TMZ reports that the Swift wasn’t happy that Harris took most of the credit for the song and was hurt by what he said in an interview with Ryan Seacrest on the day of the song’s release. Seacrest had asked Harris, “Will you do a collaboration with your girlfriend?”
Calvin replied, “You know we haven’t even spoken about it. I can’t see it happening though.”
Harris’ tweets then became more personal, referencing her new romance. Harris and Swift broke up in May, and Swift has already been spotted spending time with Avengers actor Tom Hiddleston.
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

Harris also brought up the singer’s rumored feud with Katy Perry:
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

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

Perry, who didn’t respond directly to the news, tweeted out a Hillary Clinton meme today shortly after Harris’ tweets:

Perry also retweeted a tweet she originally posted a year ago:
Time, the ultimate truth teller.

Swift has yet to respond to Harris’ rant.
