He is too young to be this mega famous, the industry control these young artists and work them to death until they have a breakdown/turn to drugs.
Britney shaved her head to try and break free from her controllers but they got her back and now she is all doped up on meds to keep her working and bringing in the big money.
She looks dead in the eyes all the time like a robot. Justin will be the same. The American celebs are always messed up the bigger they get. Then they kill them to make more money!..think of poor Whitney.
