Taylor Swift Wrote Calvin Harris & Rihanna's 'This Is What You Came For'

The cat is out of the bag.



Taylor Swift and Calvin Harris learned to never mix business with pleasure.

Swift's rep confirmed to People that the pop singer ghostwrote Harris and Rihanna's "This Is What You Came For" under the pseudonym Nils Sjoberg.

This revelation comes after reports emerged that the 1989 artist recorded a demo of the song on piano and serviced it Harris. According to TMZ, they both went into the studio and recorded a full demo with Taylor on vocals, but they later agreed that their collaboration as a couple would overshadow the song.


In April, Calvin released the song featuring Rihanna and joined On Air with Ryan Seacrest for an accompanying interview. When asked if he would ever collaborate with Swift, he said, "You know we haven't even spoken about it. I can't see it happening."

According to TMZ, Swift -- who still retains the publishing rights to the song -- was "hurt and felt Calvin took it too far," which may have been a catalyst for their split.
