The phrase “we belong together” feels very in character for Styles – who launched his last album with the slogan “treat people with kindness”.

It’s also the name of a Mariah Carey song, so maybe he’s been training to hit her infamous whistle notes in his time off?

Either way, fans are ravenous for more information.

“It’s happening?!” said one, kicking off a long discussion on a Reddit forum dedicated to Styles, external.

There, people speculated that a new logo – 12 arrows emanating from the centre of a circle – could mean there will be 12 tracks on the new record.

Some of the posters also carry extra text, which could be song titles or lyrics.

Among them are “let the light in” (Berlin), “it’s all waiting there” (Naples) and “here we go again” (Manchester).

Nothing has been confirmed yet – and there’s always the possibility that Styles is simply teasing the release of a concert film.

Whatever happens, though, fans are ready.
