But the drama unfolded when one of Swift's rep said that she wrote the song under the pseudonym Nils Sjoberg. Currently, the music performing rights databases show "This Is What You Came" for was co-written by both "Nils Sjoberg" and Harris, who used his real name-Adam Wiles. According to reports, Harris is hurt over this recent development. However, he did confirm that she sang a little on the song. He even praised her at being an amazing lyric writer. " I wrote the music, produced the song, arranged it and cut the vocals though," he explained.

He further added that Taylor wanted it to be a secret that is why there was a pseudonym. But he pointed out that it was a low blow that her and her team would make him look bad. At the time the single was released, Harris told Ryan Seacrest that a collaboration with the pop star may not happen.
