Justin Bieber is celebrating the release of his sophomore album 'My World 2.0' today! According to Nightline, over 1 million copies were pre-ordered in the U.S. alone, and for the 16-year-old pop/R&B singer, the best is yet to come.

Justin is making rounds on the TV circuit today, promoting the release on The View, 106 and Park and Late Night With David Letterman. He's said that he feels "blessed and grateful," and just after the stroke of midnight, he wrote a special message to his fans on Facebook: "MY WORLD 2.0 is here!!! Thank you all for changing my life. ENJOY."

Justin will be embarking on a full North American tour this summer along with his good friend Sean Kingston, who also appears on Justin's latest single, 'Eenie Meenie.'
