I'm going to assume you either are male (and thus were never a teenage girl) or if you are female, you were remarkably mature in your teens. I think at a certain age girls go crazy over whoever the flavor of the day is, whether its screaming and crying for the Beatles or screaming for Justin Bieber.
I agree with some other posters. Let's just let this kid alone. Some day he will no longer be a star and hopefully he'll be able to accomodate himself to that without turning to drugs or suicide.
...evil mickey owns him.
I don't think I would have gone for the Bieber.
However, I do appreciate that he seems fairly clean-cut and also wish him no harm adjusting when he loses his fame.
