Niall Horan knows better than almost anyone that One Direction's Harry Styles loves to be naked. Don't get the wrong idea - there's no Narry bromance going on here, it's just that the guys spend a lot of time together and, when you're constantly sharing close quarters, they're bound to see some things they might not otherwise.
Niall also seems to think that he knows the real reason that the ladies find Harry Styles so attractive - and it actually has nothing to do with his preference to wear as few clothes as possible.
Niall Horan claims that Harry's secret is, instead, in his curly locks: "He has all the power in his curls. The women love him."
What's interesting is that it seems Hazza's a bit insecure with his body and feels the need to bulk up a bit in order to look more manly.
Teenage boys seem to agree with Niall on this one - Harry's hairstyle is now requested at salons far more often than Justin Bieber's famous cut!
