Will pop singer, Justin Bieber, 18, last as long as his mentor, Usher Raymond, 34. They both started as child stars at age 15, releasing debut albums that were pop culture hits. Usher's career was launched with the the song "Think Of You." While Bieber’s debut single was titled "Baby."

As much as Raymond has been reusing items from his own career for Bieber’s, even pinching stuff from rival Justin Timberlake, will it work. Will Bieber stand the test of time, in an industry known for being fickle and chewing up and spitting out former child stars.
