One Direction's curly-haired heartthrob Harry Styles hasn't always had the same look and a photograph that has been shared online today has proven that.

The picture, which surfaced a while ago, has spread across social networking sites today and shows the 'Little Things' singer with a poker-straight 'do.

Back in February, a series of pre-fame snapshots of all of the One Direction band members went viral and they showed the lads in their younger years posing for entertaining 'Myspace'-type pictures with their friends and messing around at school.

Meanwhile, singer Niall Horan took to his official Twitter page earlier today (March 7) and told his 10.2 million followers that he has been working on new music with the McFly boys: "Me, @dannymcfly and @tommcfly have made a revelation today!"

Tom Fletcher, from McFly, then expressed his excitement about their working collaboration and Horan replied: "@tommcfly u know it lads! always an adventure! #WWS @dannymcfly! Love you boys."
