Bieber gets it from air-hostess

He's not yet fully a man, so 17-year-old Justin Bieber shouldn't take it amiss.

Recently, the teen pop sensation was on a Qantas flight from Sydney to Melbourne when he decided to walk around while the plane was still taxiing. Promptly, he was pulled up by an air-hostess who scolded Bieber for "acting like a child".

She also lectured him about "respecting her workplace", and that she was treating him like a child because he was acting like one. Bieber promptly apologised for his behaviour and returned to his seat.

Errr... maybe he should've also shown the air-hostess some proof of his age?
