They’ve become a legend on the Internet. No, we don’t mean One Direction. We mean Harry Styles’ two extra nipples. They’ve been the subject of countless gossip blogs and even have their own Tumblr.

And over the weekend in Chicago, they got exposed to America.

It seems Styles’ bandmates, Liam Payne and Zayn Malik decided to pull a prank on him during their show at the Allstate Arena. And the prank was ripping his shirt open — to expose the legendary four nipples. Quite a few astute fans got photos of the few moments Styles’ chest was exposed, but this was our favorite.

And there are plenty of videos floating around, but this was one of the first.

The guys continue their march across America the coming week with shows in San Diego, Las Vegas and Phoenix. Who knows what will get exposed next.
