There's been a longstanding rumour that Taylor Swift was behind the writing of Rihanna and Calvin Harris' hit This Is What You Came For - it's one of Taylor Swift fans' favourite theories.
She's finally just confirmed it, saying she wrote the song under the fake name Nils Sjöberg, which she chose because of how common those names were in Sweden.
Speaking to Beatles legend Paul McCartney during an interview with Rolling Stone, Taylor explained why she uses a pseudonym, as well as talked about the concept of hiding your identity for the sake of the music.
Speaking about the idea of having an alter-ego, Taylor says, “I think when a pseudonym comes in is when you still have a love for making the work, and you don’t want the work to become overshadowed by this thing that’s been built around you, based on what people know about you."
During the interview, Paul asked if she'd ever written under a fake name. Taylor replied, “Oh, yeah. I think it is now, but it wasn’t. I wrote under the name Nils Sjöberg because those are two of the most popular names of Swedish males.
"I wrote this song called This Is What You Came For that Rihanna ended up singing. And nobody knew for a while.” Taylor didn't just write the song, but her vocals are also on the track - disguised under RiRi's vocals.

Next time you see the name Nils Sjöberg, you'll know who really wrote the track. We've got a feeling this isn't the last we've heard from Taylor's pseudonym.
