Story highlights

Taylor Swift secretly wrote "This Is What You Came For"

Calvin Harris had quite a bit to say about her reveal

CNN  — 

Just when you thought Taylor Swift’s breakup with DJ Calvin Harris was amicable and so last month, things have gone south Hiddleswiftly.

The former couple apparently mixed business with pleasure and the result while catchy, isn’t playing out pretty. A representative of Swift tells CNN the pop star wrote the song “This Is What You Came For,” under the pseudonym,”Nils Sjoberg.” The hit, recorded by Harris and Rihanna, has been at the top of the charts all summer.

Swift’s contribution, of course, was not news to Harris, who one would assume was there when the collaboration happened. But he quickly launched into live-stream-of-conscious mode about the reveal in a series of tweets.

Though initially complimenting Swift as an “amazing lyric writer” and saying his ex “smashed it as usual,” Harris was not pleased that sole credit was going to one of the most successful songwriters of all time.

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

What Harris tweeted next reads slightly bitter ex-boyfriend.

“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 added, referring to Swift’s relationship with actor Tom Hiddleston. “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.”

Swift is no stranger to social media spats, previously exchanging words with Nicki Minaj and Katy Perry.

Harris concludes by appearing to address Swift directly, “Please focus on the positive aspects of YOUR life because you’ve earned a great one.”

Considering Swift has spent her summer throwing celebrity-packed Fourth of July parties and locking lips with Loki, it seems she’s already doing so. Let’s just hope she and Hiddleston keep their collaborations on the dance floor and out of the studio.
