Justin Bieber seemingly did it all in 2010. He sold out concerts, filmed a movie, released two albums and set girls hearts aflutter — all in the span of 12 months. Not only is he arguably the biggest pop star in the world, he's also pals with some of hip-hop's biggest names (just ask Drake, Ludacris and Kanye West if you don't believe us), and he chills with some of the prettiest girls in the game thanks to friendships with ladies like Kim Kardashian, Taylor Swift and Selena Gomez.
This really is Justin Bieber's world, and we're all just living in it. For a kid from a small town in Canada, Bieber's meteoric rise to fame from Internet sensation to bona fide musical superstar may have seemed fast, but let's face it: Bieber is the real deal.

The second half of 2010 was just as busy for the star.

(He followed through on all those promises by year's end.) By the end of August, [article id="1646789"]Kanye West's remix of "Runaway Love"[/article] hit the world, and it was announced that Bieber would be performing at the VMAs. He also filmed the concert portions of [article id="1646937"]his 3-D movie[/article] at Madison Square Garden.
[article id="1647731"]JB hit the stage at the VMAs[/article] in September and even took home [article id="1647673"]his first-ever Moonman[/article].

In November, he released his book and his [article id="1652950"]My Worlds Acoustic[/article] album and took home a few [article id="1652783"]American Music Awards[/article].
