Midnights, the Taylor Swift album, has once again sparked fans’ interest to find out the truth behind William Bowery. It has been a while since Joe Alwyn admitted that he is one of the masterminds behind some of Taylor Swift’s recent albums. He has also revealed why he kept his collaboration with Taylor a secret.

A few hours after releasing her tenth studio album named Midnights, Taylor surprised netizens by releasing seven additional tracks in a 3 AM version of the album. She provided Swifties with 20 brand-new songs that are jam-packed with thoughtful lyrics.

The Bad Blood singer has already admitted that her relationship with her longtime boyfriend Joe Alwyn served as inspiration for the album's opening track, Lavender Haze, and it appears that another song Sweet Nothing, may also be about their love affair. William Bowery is also credited in Midnights, and though fans now know it's Joe's pseudonym, it's a bit of a mystery as to why he chose the moniker.

Alwyn has been a member of the creative team behind the Wildest Dreams singer’s recent album Midnights after her previous albums Folklore and Evermore.

Sweet Nothing is one of the hardcore romantic songs of this album. It seems well-suited to capture the dynamic between Taylor and her beau, her longtime boyfriend of six years and one of the co-writers of the song.

A safe haven from the chaos of the outside world, the song is a personal ode to all the sweet things of spending one’s days with another person.

Alwyn is credited as a songwriter for Sweet Nothing under the pseudonym William Bowery, leading fans to believe he created the song's catchy piano riff, given his previous ivory-tickling contributions to the albums Folklore and Evermore.

The song's lyrics also make reference to Swift's difficult life as a celebrity and the ways that her relationship with Alwyn has given her solace.

Taylor Swift Confirmed That William Bowery Is Joe Alwyn

“There’s been a lot of discussion about William Bowery and his identity because it’s not a real person. So, William Bowery is Joe, as we know”, Swift said in Folklore: The Long Pond Studio Sessions.

She later added, “Joe plays piano beautifully, and he’s always just playing and making things up and kind of creating things. And ‘Exile’ was crazy because Joe had written that entire piano part."

In an episode of Jimmy Kimmel Live, Taylor was asked about her long-time boyfriend Joe Alwyn receiving songwriting credits under the name William Bowery on her two surprise albums, Folklore and Evermore.

"Your boyfriend wrote some of the lyrics to some of the songs under a pseudonym, William Bowery. Who chose that name? Did you choose that, or did he?,” asked Kimmel.

The Lover singer paused before responding, as though she was unsure about revealing the mystery around the pen name. She finally answered, "He did."

Jimmy then exercised due diligence by inquiring about the significance of the chosen name. She promptly resisted, and said, "You gotta ask him because it's really more his story than mine."

How Did Joe Come Up With His Pseudonym?

Many artists including Taylor Swift have used pseudonyms to keep their identity a secret while writing for other artists. Joe Alwyn explained why he decided to adopt the pseudonym while attending The Kelly Clarkson Show. Alwyn pointed out that it has a special significance.

"It was a combination of William, my great-grandfather, who I never actually met, (who) was a composer," the Conversations With Friends star said. "He wrote a lot of classical music and he wrote a lot of film scores. And then Bowery is the area in New York that I spent a lot of time in when I first went over there."

During the latter part of the discussion, Kelly said that the name sounded "very fancy." Alwyn chuckled and said that William Bowery sounded like "a kind of Agatha Christie character who should be wearing a monocle with a big mustache".

Taylor And Joe's Collaboration Wasn't Planned

In an interview with GQ Hype, Joe opened up about his experience of writing with the All Too Well singer. “It was really the most accidental thing to happen in lockdown," he said in the interview.

He further said, "It wasn’t like, ‘It’s three o’clock, it’s time to write a song! It was just messing around on a piano and singing badly and being overheard and then thinking, you know, what if we tried to get to the end of it together?"

"It was fun to do together, and I was proud of it. It was nice getting such a positive reception," he later added.

Before contributing as the songwriter of Sweet Nothing, Joe co-produced several songs on Swift's two albums, Folklore and Evermore.

The songs included Exile, Betty, My Tears Ricochet, August, This Is Me Trying, and Illicit Affairs. Alwyn later won a Grammy for his work on Folklore. The actor contributed to Swift's songs Evermore, Coney Island, and Champagne Problems on the album Evermore.
