UPDATE: Harris and Katy Perry respond.


UPDATE 2: Katy Perry hilariously responded to the entire debacle by posting this GIF of Hillary Clinton and Re-Tweeting her 2015 Tweet: “Time, the ultimate truth teller.”

UPDATE 1: Calvin Harris not only confirms it, but adds that she’s featured on the song as well:

Then he comes for blood:


Lightning strikes every time she moves.

Taylor Swift might be on a mission to prove something right now re: Tom Hiddleston, but that doesn’t take away the fact she’s an incredible writer. Take for instance Calvin Harris’s new song with Rihanna, “This Is What You Came For,” which according to new reports from TMZ was actually written by Swift under the name Nils Sjoberg.

“During their relationship, Taylor wrote the song, sat down at a piano and did a demo into her iPhone,” TMZ reports. “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. 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.”

Here’s where the trouble begins.

Harris gave an interview earlier this year, and said he probably would not work with Swift professionally. A source is calling that moment “the breaking point in the relationship.”

The Met Gala was just days later, when Taylor famously danced with Tom Hiddleston.

Interestingly, Swift could actually block Harris from performing it (like he did with ex-girlfriend Rita Ora), but apparently Swift has no interest in doing that.

Who knew Swift could write a legitimate club song?
