He was on his way back from  Australia last weekend, when Justin Bieber and his people where getting a little  raucous for their fellow passengers to handle on a 12-hr Air New Zealand flight.

They where shouting very loud and that’s not it hey kept dropping colorful 4-letter bombs… among other expletives.

But after a while, one woman had enough! The mother of two confidently walked over to the Biebs and demanded:

“Stop yelling curse words and using that kind of language on a plane. It’s not appropriate!”

Justin was totally embarrassed and quickly apologized to his fellow passenger — or so we hear. But Justin is a good boy; we don’t imagine he was anything but humbled by the woman’s request. And after all, he is still a youngin’! He’ll learn in time.

Ohh Justin mummy will have to was your mouth out with some soap LOL.
