Justin Bieber sparks showdown with Niall Horan's neighbours

Justin Bieber sparked a dispute with Niall Horan's neighbours during an impromptu jam session at the One Direction star's house this week (beg10Sep12).

The pop superstar landed in the U.K. on Tuesday (11Sep12) for a whirlwind promotional visit and he wasted no time in hooking up with his boyband pal.

Bieber went over to Horan's home and the pair stayed up until the early hours of the morning playing music together, but the jam session infuriated the other residents of the apartment block.

The Baby hitmaker tells Britain's Metro newspaper, "We have a great time together. I went over to Niall's house yesterday. Think we p**sed people off a little bit. We were making a little jam session at three in the morning and he lives in this apartment. So there's people underneath him and we were playing really loud and all the sudden we hear 'bang, bang, bang' on the door and this guy shouted, 'Keep it down'. It was crazy."
