3 of 14: Few pop sensations have taken over as quickly and thoroughly as Justin Bieber. In 2010, he released his first full studio album, 'My World 2.0' and debuted his 3D biopic concert film, 'Justin Bieber: Never Say Never.' The 17-year-old became a household name seemingly overnight.

"From the minute I met Justin, I knew this kid possessed a certain confidence that only a star could have," Usher wrote in Time magazine. "He was born a star. He knew what he wanted to accomplish; all he had to do was get everyone else to believe it."
