Justin Bieber must be used to all kinds of requests from female fans, but when he was asked to quiet down with his shrill swearing whilst on a 12-hour Air New Zealand flight back from his promotional tour Down Under, it was probably a request that he is not all too familiar with.

TMZ reports that the 18-year-old 'Boyfriend' singer and his entourage were blurting out increasingly more offensive curse words, getting louder and louder as they were doing so. After so long, one female passenger had become so fed up with it that she finally stepped up to Bieber and told him to hush.

TMZ go on to report that the woman, a mother of two, walked over and requested Justin to "stop yelling curse words and using that kind of language on a plane." As "It's not appropriate."

Whether her children were with her or not, or whether any other sensitive ears where on the plane, is unknown.

A source close to Justin told the celebrity gossip site that the singer was completely embarrassed by the situation and was quick to apologize to the woman on behalf of himself and the rest of his entourage.

This comes after news that Justin's neighbours are becoming increasingly fed up with the singer's home behaviour. Neighbours, including actor Dax Shepard, have damned the singer for his loud music, partying and constant stream of paparazzi.
