You'd be hard pressed to have avoided One Direction mania since the boy band stormed to global success after finishing third on The X Factor in 2010. With his curly locks and an eye for the ladies, Harry Styles soon became the band's hearthrob. He was involved in a high profile relationship Xtra Factor presenter Caroline Flack, which drew controversy for the 14 year age gap. The couple split in January 2011, and since Harry has been linked to a string of women including Emily Atack, Caggie Dunlop and Natalie Imbruglia. He has also developed a blossoming bromance with Radio 1 DJ Nick Grimshaw and the pair are regularly spotted on nights out together. Along with his One Direction bandmates, Harry has achieved worldwide fame and success, and the lads are currently on their second album, entitled Take Me Home.
