Taylor Swift will release her eighth studio album, “Folklore,” on Friday.
In her announcement, Swift praised her four main collaborators: The National’s Aaron Dessner, Bon Iver, Jack Antonoff, and a mysterious person named William Bowery.
According to Swift, Bowery cowrote two songs on “Folklore” — but the name doesn’t belong to a known artist or carry any existing songwriting credits.
Fans are speculating that “William Bowery” is a pseudonym, possibly for Swift’s brother Austin or her boyfriend, Joe Alwyn.
Back in May, Swift’s brother reportedly recorded a cover of “Look What You Made Me Do” using a fake band name.
Swift herself has also been known to use the pseudonym Nils Sjöberg.
