Recently, Justin Bieber has been doing some homework. And it involves figuring out why other teen stars didn't make it in adulthood! "Justin doesn't study the people who made it," JB's manager Scooter Braun commented during a segment for Barbara Walters' special 10 Most Fascinating People of 2010. "He likes to look up to the people who used to be the so-called Justin Biebers before him and didn't go anywhere. He wants to see why they didn't go anywhere. The general feeling we get is that it had nothing to do with their talent an everything to do with their personal life. Like the kids fall into drugs and destroy their own trajectory."
