Boyband One Direction grace the cover of the forthcoming new edition of Seventeen magazine in the USA and in the accompanying interview they open up about their relationships with each other as a group. 

Member Louis Tomlinson told the publication that he prides himself on being the one that makes the other lads laugh while they're on the road together: “I’ve been labeled the prankster. I change the words of songs when the guys least expect it – their reactions are priceless.”

Singer Niall Horan, meanwhile, praised bandmate Liam Payne's impressive physique: "Payne-o! That fellow is ripped. He works hard at it though, so I’ll give him that.” Payne, in turn, revealed the one must-have product they all rely on while travelling: "Toothpaste. Got to have fresh breath, especially when we’re singing in each other’s faces."

'Best Song Ever' heartthrob Harry Styles added that they all like to sing in the shower: "We all do! We can sometimes hear Liam through the wall.” The December/January issue of Seventeen magazine is due to hit newsstands on November 26.
