Justin Bieber admits he ''p***ed off'' Niall Horan's Neighbours when the pair enjoyed a 3am musical Jam session.

The 'Boyfriend' singer recently visited the One Direction singer's London apartment and when they started playing music together in the early hours of the morning the other residents in Niall's block were not impressed.

Justin said: ''We have a great time together. I went over to Niall's house the other day. Think we p***ed 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.''

While Justin obviously enjoys loud music, the 18-year-old heartthrob likes to relax by playing silent board game chess.

He told the Metro newspaper: ''I don't know if people know this but I am pretty good at chess. I was always on the chess team at school when I was younger. I'm not into speedy chess. I need to think. I can go slow.''
