Taylor Swift co-wrote and features on "This Is What You Came For", the #banger by Calvin Harris and Rihanna.

She was credited as Nils Sjoberg, keeping it schtum until now, for some reason - her people have confirmed the co-write to People.

It's unclear exactly what bit she appears on - harmonies perhaps? - but she's in the mix somewhere. It's probably not exactly what people wanted when they asked for a Taylor x Calvin song, or even a Taylor x Rihanna song (did people ask for that?), but oh well, it's technically here nonetheless.

Ex-beau Harris took to Twitter to confirm the news, calling her an "amazing lyric writer" before stoking the Twitter beef /calling her out.

I wrote the music, produced the song, arranged it and cut the vocals though. And initially she wanted it kept secret, hence the pseudonym
