This morning Justin Bieber was present in two of Twitter's top ten global trending topics, a feat usually reserved for big events like award shows and major sports outings. Seeing as this is just any old Tuesday in February, what gives?

We asked our Facebook friends about the teen pop phenomenon this morning and the resounding answer was, "WHO?" Still, like him or not, Bieber is a true Internet star, who was plucked from in front of his webcam in Canada and thrown into the real music world, working with heavyweights like Usher and releasing his debut album on Island Def Jam Records. Now he is even taking over Lionel Richie's singing duties in the 'We Are The World' remake. But what makes this 15-year-old stand out from the rest of the aspiring singers out there? Perhaps it's his legion of die-hard young fans. PopEater breaks down his rise to fame ... after the jump.

Bieber's fame is not just buzz, either. Last November, Bieber's debut album 'My World' debuted at #6 on the U.S. Billboard 200 selling 137,000 copies in its first week. At the time, the album was the strongest debut from a new artist before Susan Boyle pounced on the scene and subsequently decimated all competition the following month. Even more impressive, Bieber became the first solo artist in Billboard's history to have at least 4 singles enter the Top 40-- before the album even dropped.

These days you can regularly find Bieber presenting at the Grammy Awards or hobnobbing with superstars like Rihanna and Beyonce (both of whom he's expressed having crushes on), but the true key to his success is never forgetting about the fans that thrust him into the spotlight in the first place (as evidenced by the riots he caused at a local mall last fall).
