Taylor Swift Helps Pen Calvin Harris and Rihanna’s hit single “This Is What You Came For”

It looks like Taylor Swift had a hand in writing Calvin Harris and Rihanna’s hit single “This Is What You Came For”. The star wrote the lyrics for the song under the pseudonym Nils Sjoberg.

TMZ is reporting, Taylor “wrote the song, sat down at a piano and did a demo into her iPhone,” and then sent it to Calvin. Calvin took to his Twitter today, July 13, to confirm that Taylor did write the lyrics and she did sing a little on it, but he “wrote the music, produced the song, arranged it and cut the vocals”.

He also confirmed that Taylor wanted to keep the song a secret saying, “Initially she wanted it kept secret, hence the pseudonym”.
