Earnings: $55 million. The young crooner may have just turned 18 but he’s raking in more dough than his older cohorts. Expect him to continue with the revenue intake once his new album drops this year. If his new single Boyfriend is any indication, expect a more mature turn from Selena Gomez’ beau and the possibility of big sales. It is Beiber after all. He could burp for 12 tracks and still sell tons of records.
