British boy band member Harry Styles was left standing -- or singing rather -- with his pants around his knees after his fellow 1D'er Liam Payne pranked him by pulling his pants down on stage.
Harry laughed off the prank and continued singing What Makes You Beautiful while attempting to pull his skinny jeans back up again (a feat unto itself really).
While the prank left fans swooning -- because let's face it, those 1D fans would have been praying for a moment like that to occur -- many are now questioning Harry's choice of underwear.
The 'pantsing' incident revealed Harry was weraing a small pair of black boy leg briefs. So far, so normal. But as Harry turned around, he also revealed straps attached to the undies that wrapped around the backs of his legs.
Another tweeted: "harry styles!!!can u please explain it to me why do u have this kind of underwear?!and louis u look shocked???"
Over on Buzzfeed, Harry's interesting choice of underwear was also noted, with the web trend site posting: "And then we noticed his underwear... WHAT?"
Much of the speculation seems to suggest Harry was wearing some kind of jock strap, although we wouldn't have thought that singing on stage required a male support garment.
This revelation may have left many scratching their heads, it's not the first interesting underwear choice for Harry.
In March, a flashback photo did the rounds on the internet revealed the singer ironing a pair boxers while wearing a gold g-string. It was taken back in 2010 while Harry was a contestant on The X Factor in the UK.
Given Harry's interesting choice of underwear so far, we won't speculate as to what will be revealed next. We just hope the next time it happens that he is wearing underwear!Harry gets nailed in the groin by a flying shoe
