One Direction's Harry Styles is known to love frolicking half naked. Thanks to his group mate, Niall Horan, Harry Styles is caught shirtless and wearing only a tiny pair of boxer briefs. Ladies, get ready to faint at the sight of Harry Styles in his Tommy Hilfiger underwear.

Thanks to Simon Cowell, the world has got their sights on British boy band, One Direction, and by the looks of it - no other boyband today can beat their swag. From making Selena Gomez and Taylor Swift dance and sing along to "What Makes You Beautiful" at the recent Nickelodeon Kids Choice Awards to creating fan frenzy down under, One Direction's Harry Styles newest video is sure to cause sleepless nights for their fan base.

In Harry's most recent shot swimming in the great big blue of Australia, Harry amusingly admits to having four nipples even when the paparazzi photos show only two.

"I've got four nipples," says Harry in an interview with Star Magazine, April 30 issue. "I must have been a twin, but the other one went away and left its nipples behind."

In a recent video shared by Niall Horan, Niall hilariously exposes his fellow boy band member, Harry, who looks as if he's busy shaving his legs wearing only a pair of boxer shorts. While this may be just a sneak preview of what's to come on their DVD, "Up All Night - The Live Tour", it's sure enough to cause whopping sales. Niall even took to Twitter announcing his late April fool's joke on Harry Styles.

"As we promised here is......#harryinhispants bit.ly/HarryPants," tweeted Niall. Even group member Liam joins in on the fun when he faces the camera.

"No one wants to see that-do you?" asked Liam. Knowing their fan base, every one surely begs to differ.

Thanks to Niall, fans of the adorable Harry now have videos of him half naked. This little video is also enough reason for fans to request Niall to do more or even spy on the other One Direction members.
