The couple has reportedly been dating since 2016 but the two rarely mention each other in interviews or on social media. Besides making a rare red carpet appearance together, they choose to keep their relationship as private as possible.
"We live in a culture that people expect so much to be given," Alwyn said in the WSJ magazine interview. "So that if you’re not posting all the time about what you’re doing, how you’re spending a day or how you made a breakfast, does that make you a recluse?”
Of course, where fans truly learn about Alwyn and Swift is in Swift's music. Songs like Gorgeous, Lover,London Boy, and Peace are speculated to be about Alwyn.
Additionally, on Swift's album, evermore, Alwyn is credited with songwriting credit under the pseudonym "William Bowery".
