One Direction: "We've got stubble, we’re turning into men"
One Direction have admitted that they have had to "grow up fast" after being catapulted into the limelight.
The quintet were formed from five starry-eyed solo contestants on the X Factor in 2010.
All of them were teenagers at the time and speaking to Top of the Pops magazine, Niall Horan said that they are now a world away from their fresh-faced beginnings.
He said: "I mean we were all just kids…You get pushed straight in and have to grow up fast…We've got bigger, we've got stubble, we're turning into men."
Bandmate Zayn Malik said: "We've all changed. None of us really knew each other and none of us was really prepared. I found it hard talking to people, answering questions, but then you realise everyone is in the same boat. You can’t take yourself too seriously, and you all start to relax into being who you are."
One Direction's music meanwhile has taken a rockier turn as they have grown up.
