Actor Joe Alwyn is officially a Grammy Award winner due to his contributions to Taylor Swift's eighth studio album, "Folklore."
First reported by People, Alwyn was recently listed as a recipient of the Album of the Year accolade on the Grammy Awards official website. "Folklore" snagged the Album of the Year title at the 2021 Grammy Awards, making Swift the first woman in history to win the award three times.
In "Folklore: The Long Pond Studio Sessions," Swift revealed that Alwyn was previously credited under the pseudonym William Bowery and helped write "Exile" and "Betty." Alwyn also co-produced "Exile," "My Tears Ricochet," "August," "This Is Me Trying," "Illicit Affairs," and "Betty."
"There's been a lot of discussion about William Bowery and his identity 'cause it's not a real person," said Swift, 31, during the documentary. "William Bowery is Joe."
Swift, who's been dating Alwyn for four years, added: "Joe plays piano beautifully, and he's always just playing and making things up and kind of creating things."
Swift claimed that Alwyn wrote the entire piano portion and the first verse of the song, "Exile," by himself.
"I was entranced and asked if we could keep writing that one," she said.
Alwyn was also credited with co-writing three songs on Swift's ninth studio album, "Evermore," which was released in December 2020. He contributed to "Champagne Problems," "Evermore," and "Coney Island."
During this year's Grammy Awards, Swift mentioned Alwyn in her acceptance speech for Album of the Year.
"Joe is the first person that I play every single song that I write, and I had the best time writing songs with you in quarantine," she said.
Taylor Swift previously revealed that her boyfriend, Joe Alwyn, wrote and produced tracks on "Folklore" under the pseudonym William Bowery.
