Harry Styles has caused some major speculation after performing a song fans are deeming a "bisexual anthem" during the European leg of his world tour.
The ex-One Direction singer performed in Basel, Switzerland on Sunday (local time) and debuted some previously unreleased music for the excited crowd.

"Two years ago I started making my very first album on my own... I want to thank you for your support," he told the audience.
"We wrote a lot of songs for the album and we chose 10. And we've never played this one before."
It was one of the songs, 'Medicine' that has had the biggest reaction, with fans caught up on a particular set of lyrics.
"The boys and the girls are here, I mess around with them, And I'm okay with it. I'm coming down, I figured out I kinda like it, And when I sleep I'm gonna dream of how you tasted," Styles appears to sing. (The line starts around 2:08 in the clip above.)
The first line in particular caused Styles' fans to turn to Twitter, convinced the singer was admitting revelations over his own sexuality.
Styles has avoided talking openly about his sexuality in the past.
"No, I've never felt the need to [label my sexuality] really. No," he told The Sun last year. "I don't feel like it's something I've ever felt like I have to explain about myself."
