Justin Bieber's recent exploits of alleged drug use, showing up late to his own concert and lunging at photographers have led some to suggest that the 19-year-old Canadian pop star is out of control.
Maybe he is and he'll spiral into obscurity, or maybe he's making the inevitable jump from good boy to bad boy, as so many have before him. Drugs, fighting, tattoos and saying "Swaggy" are all common behaviours of the good boy gone bad. Bieber will find his way. He's just 19, and one of the most famous people in the world. Don't act like you can relate.
