The musician is a fan of these elaborate, cryptic campaigns.

In 2022, he launched the Harry’s House album with a website called You Are Home, external, featuring an animated door that would open to show a different image every day: A photo of Earth, Haruki Murakami’s novel The Wind-Up Bird Chronicle, or Cavallini’s mushroom puzzle.

For Fine Line, Styles plastered cities around the world with posters that asked, “Do you know who you are?”

Again, there was a website, where fans could receive positive affirmations like “you are distanced, but not far from my heart”, or “treat people with kindness”, each signed with the phrase, “Love, H”.

No further details of Styles’ comeback were revealed on Thursday – but rumours have circulated for months that he will embark on a world tour this summer.

Among the supposed engagements on his calendar are residencies at London’s Wembley Stadium and New York’s Madison Square Garden.

If true, it adds up to a stacked summer of concerts, with stadium tours by BTS, Bruno Mars, The Weeknd and Foo Fighters already confirmed in recent weeks.
