Claim to fame: Kylie Minogue's little sister has followed in her sibling's international footsteps. As a prolific singer, actress, model, and well-known judge on both The X-Factor and Australia's Got Talent, her (rightfully) excessive exposure lead to Metro UK crowning her as Celebrity of the Year in 2010. Unlike MTV's Skins and smaller-sized meals, she's one international trend the U.S. should actually adopt.
