Taylor Swift Actually Wrote 'This Is What You Came For' Before Calvin Harris Break Up

Taylor Swift‘s rep has confirmed that she wrote Calvin Harris and Rihanna‘s hit “This Is What You Came For” before their breakup.

“Taylor Swift wrote ‘This Is What You Came For’ under the pseudonym Nils Sjoberg,” Taylor‘s rep told People.

TMZ reveals that Taylor was upset because Calvin disrespected her when asked if they would ever work together. “You know, we haven’t even spoken about it. I can’t see it happening though,” Calvin said in an interview in April before their breakup. Sources say this was the breaking point in the relationship.

The site also reports that Taylor wrote the song and recorded it on her iPhone while playing piano. Calvin loved it, so they went into the studio and recorded it with Taylor on vocals. Taylor has kept the publishing rights, but doesn’t plan to ban Calvin from performing the song.
