(TMZ) - Justin Bieber fielded an unusual request from a passenger on an international flight - and it went something like this: shut your expletive-filled pie hole! Please.
It all happened during the Biebs' return from a Down Under promotional tour. Sources on the 12-hour Air New Zealand flight last weekend tell TMZ JB was surrounded by his entourage in first class when things started getting out of hand. 18-year-old Justin and his posse were blurting out cuss words - including some 4-letter selections - and getting so loud... a female passenger finally stepped to Bieber.
The woman- a mother of 2 - walked over and asked Justin to "stop yelling curse words and using that kind of language on a plane. It's not appropriate."
A source close to Justin says he was completely embarrassed and quickly apologized to the woman.
