Probably because he is not as popular as Bieber and only came to the fore earlier this year?
Is he attitude what he's learnt at home but hasn't learnt not to let it show it in public?
Why did he think aged 14 it was the norm to go to clubs?
Wasn't he chaperoned, did his parents express concern?
To me it looks like dad is grooming him.
Huh? Jaden smith has been big for a while....ever since pursuit of happyness.
