Justin Bieber

For a Canadian, Justin Bieber is sure living the American dream! After his mother uploaded videos of Justin covering R&B and pop hits to YouTube, Usher noticed the young singer and became his mentor. His 2009 debut album My World (along with his notorious hair style) solidified Justin as the teen sensation of the new millenium. The world quickly developed a bad case of Bieber Fever which has driven some fans to issue death threats to Kim Kardashian after picture of her and the singer hit Twitter. He has since released a second platinum album, his own 3D movie Never Say Never, an autobiography and performed at the White House — all by the age of 16. Justin has also found the girl of his dreams in Disney darling Selena Gomez, whom he began dating in 2011.
