Surely this week’s sartorial headline belonged to Harry Styles. After a rush of images were posted on the singer’s otherwise fairly dormant Instagram feed, the talk of the GRAZIA office was Styles’ fashion evolution from boyish gingham and pop music to Gucci and rock. Of course, another headline of interest hit overnight.

Performing in Copenhagen as part of his world tour, a fan told the Sign Of The Times star she was turning 22-years-old. “Twenty-two. She’s 22, okay,” Styles told the audience. “I don’t know about…,” he began, referencing his ex-girlfriend, Taylor Swift’s, song 22. The lyrics to that track say “I don’t know about you, but I’m feeling 22.”

In evidence the fandeomeom surrounding Styles is not at all ending any time soon, the Twitter-verse became alight with shock, helped along by the singer himself who tweeted after the show, “I don’t know about, but I’m feeling 22.”

Taylor Swift and Harry Styles took a walk through Central Park in New York City in December 2012.

Styles and Swift dated briefly toward the end of 2012 and since, every track produced by the latter came with a question mark: Do Swift’s lyrics give any insight clues into her relationship with the former One Direction band member? Was her performance of I Knew You Were Trouble at the 2013 Brit Awards a not-so-subtle message to her ex-boyfriend? And did she really whisper “shut the f**k” up to friend Selena Gomez as One Direction collected an MTV award the following September?

All remained a mystery until she dropped her aptly named single Style in 2014 where Swift referenced midnight catch-ups with a long-haired man she just kept going back to. Styles addressed the former couple’s relationship status in Rolling Stone ahead of the release of his self-titled debut album last year. “I mean, I don’t know if they’re about me or not, but the issue is, she’s so good, they’re bloody everywhere,” he said. “I write from my experiences; everyone does that. I’m lucky if everything [we went through] helped create those songs. That’s what hits your heart. That’s the stuff that’s hardest to say, and it’s the stuff I talk least about. That’s the part that’s about the two people. I’m never going to tell anybody everything.”

Styles is currently dating model Camille Rowe while Swift is seeing British actor Joe Alwyn.
