You know how Bieber keeps getting into trouble with the law and his neighbours over his cars and his mates? Well this might explain why.

While the cats away, Bieber's mousey mates seem to have free reign over his kingdom, including flying around in his Ferrari and Range Rover and getting up to all sorts of no good. TMZ has footage courtesy of one seriously pissed off neighbour who decided to take matters into her own hands and record Bieber's housemates Lil Twist and Lil Za (who sound like idiots from their names alone) as they sped through the neighbourhood. They didn't take to it too well.

The pair shout from their cars before Za gets out to confront the woman saying: 'I live with Justin Bieber and you know I do. He then tells the woman, "F**k you. Get the f**k out of here.'

Bieber sure knows how to pick his mates.
