Taylor Swift and Calvin Harris Allegedly Broke Up Over ‘This Is What You Came For’

This morning, TMZ revealed that an “early fan rumor” about Calvin Harris’ latest Rihanna banger “This Is What You Came For” is true: that Taylor Swift was indeed the “creative brains” behind the track.

Not only that, but Harris’ behavior during promotion of the song is what ultimately lead Swift to break up with him.

TMZ explains:

We’ve learned an early fan rumor about the song is true, but to a deeper extent than anyone suspected. During their relationship, Taylor wrote the song, sat down at a piano and did a demo into her iPhone. She sent it to Calvin, who loved it. They both went into a studio and did a full demo with Taylor on vocals and Calvin doing the beat.

So why didn’t Swift sing the vocals on the track instead of Rihanna? Basically, they didn’t want to mix business with pleasure.

They both knew the song would be a hit, but Taylor wrote it for Calvin and both agreed it was a bad idea to let the world know they collaborated as a couple … it would overshadow the song.

So Taylor, who kept the publishing rights, used the pseudonym Nils Sjoberg on the credits.

Then flash-forward to when the song was released on April 29. That’s when Harris messed it all up.

Harris appeared on Ryan Seacrest’s radio show that day, where he was asked, “Will you do a collaboration with your girlfriend?” Harris’ response: “You know we haven’t even spoken about it. I can’t see it happening though… She’s about to take a long break, you know.”

Harris’ comment “hurt” Swift, and she felt he “took it too far.” One TMZ source even referred to this as the “breaking point” in their relationship. Flash-forward again to a week later to the Met Gala, where Swift and her now-current boyfriend Tom Hiddleston met for the first time and danced the night away.

“This Is What You Came For” was an instant hit, reaching the top 10 in all except four of the countries it has charted in. TMZ also brings up the fact that since Swift has publishing rights for the song, technically she “has the right to prohibit Calvin from performing the song, but she hasn’t and doesn’t plan to exercise that right.”

“Ironically,” they continue, “Calvin once wrote a song with then-GF Rita Ora and when they broke up he yanked her right to perform it.”

One final note: Swift’s squad is talking out in support of her now because “they’re sick of Calvin trashing Taylor and feel he should be thanking her for quietly giving him a smash hit.”

Considering Swift’s crazy-successful songwriting history and her persistent desire to protect her music (and image for that matter), this breakup theory is 100% believable.
