Harry Styles Jokingly References Taylor Swift During His Concert

Harry Styles brought up one of Taylor Swift‘s songs, and now we’re feeling the Haylor nostalgia.

The 24-year-old “Sign Of The Times” singer was on stage performing in Copenhagen, Denmark on Sunday (March 18) when he wished a fan a happy 22nd birthday.

“Twenty-two. She’s 22, okay. I don’t know about…,” he joked before stepping away from the microphone – a reference to Taylor‘s “22.” Fans went crazy when they picked up the reference! (Check out footage!)

Harry and Taylor briefly dated between 2012 and 2013.
