Harry Styles
Harry Styles was once your average mop-haired English teen. He had divorced parents, attended school, worked in a bakery and sung lead in White Eskimo, a band decent enough to win school competitions. After he competed on the British version of "The X Factor" and was paired with four other contestants to form One Direction, his life is anything but average. Despite finishing third in the contest, the boy band was given a recording contract by judge Simon Cowell and immediately started grabbing teen hearts the world over with their pop hits like "What Makes You Beautiful" and "Story Of My Life." They have released three albums since 2011, performed at the 2012 London Olympics closing ceremony, and appeared on "iCarly." Styles, the youngest member and biggest flirt of the act, has been romantically linked with TV host Caroline Flack (who was 32 to his 17), models Emma Ostilly and Cara Delevingne, singers Taylor Swift (who slighted him in song supposedly) and Rita Ora and socialite Kendall Jenner (until early 2014).
