Taylor Swift Talks About 'Folklore' Mystery Writer Credited On 'Betty' And 'Exile'

Taylor Swift ended the speculations about the mystery writer on her "Folklore" album.

Swift's fans were intrigued by the mystery writer named "William Bowery" on her album who was credited on her tracks "Betty" and "Exile." Swift confirmed that he is none other than her boyfriend, Joe Alwyn.

"There's been a lot of discussion about William Bowery and his identity. He's not a real person," Swift was quoted by Entertainment Tonight as saying in Disney+ concert film "Folklore: the long pond studio sessions."

"Bowery is Joe, as we know. And Joe, Joe plays piano beautifully, and he's always just playing and making things up and kind of creating things."

Swift added that she and Alwyn first collaborated on the song "Betty." He wrote the chorus of the song.

"I just heard Joe singing the entire, fully formed chorus of 'Betty' from another room. And I just was like, 'Hello,'" Swift continued.

"It was a step that we would never have taken because why would we have ever written a song together? This was the first time we had a conversation where I came in and I was like, 'Hey, this could be really weird and we could hate this, so could we just, because we're in quarantine and there's nothing else going on, could we just try to see what it's like if we write this song together?’"

Swift added that it was Alwyn's idea to tell the story of "Betty" from a male perspective. Swift loved the way Alwyn wrote the chorus and they eventually agreed to write it from a teenage boy's perspective by mentioning that he was only 17 and was sorry for losing the love of his life for being foolish.

The "Miss Americana" star also shared how huge Alwyn's contribution was to her song "Exile."

"'Exile' was crazy because Joe had written that entire piano part and he was singing the Bon Iver part... He was just singing it. And so, I was entranced and I asked if we could keep writing that one," she said.

"It was pretty obvious that it should be a duet, 'cause he's got such a low voice and it sounded really good sung down there in that register.”

Just recently, Swift sparked rumors that she was working on a music video for “Exile” after sharing a black and white photo with the caption, “Not a lot going on at the moment.” The last time Swift used the same caption was when she was working on something big. The photo also has clues related to "Exile" that prompted fans to speculate that she was working on something related to the single and many agreed it was a music video.
