Justin Bieber soaring with album sales, MSG show, movie

Having sold out Madison Square Garden the other night, Justin Bieber is celebrating another milestone -- he sold 4 million albums worldwide in less than a year. Bieber has now sold 3.2 million copies of his "My World" (released last November) and "My World 2.0" (March) in the US, plus 7.7 million songs digitally downloaded, according to Nielsen SoundScan.

His manager, Scooter Braun, told us: "Madison Square Garden was a big milestone. Justin is a kid who grew up in public housing with a single mom. He always said selling out the Garden was his dream." Bieber's also been shooting a movie of his life story, and celebrities -- including Miley Cyrus, Usher, Snoop Dogg and Adrian Grenier, who all attended his MSG show -- will appear in the film due out in February. Braun added, "It's a real rags-to-riches story, and shows where Justin came from and the hard work that got him to where he is now."
