Justin Bieber has revealed how an impromptu music-making session with One Direction's Niall Horan woke the neighbours up.
The Canadian pop star and the Irish boyband singer, who hung out with a "guys' night in" after the MTV Video Music Awards, decided to get together for a spontaneous jam in the early hours of the morning, which didn't go down too well with Niall's neighbours.
"I went over to Niall's house yesterday. Think we p***** people off a little bit. We were making a little jam session at three in the morning and he lives in this apartment," Justin told Metro.
"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," he recalled.
Justin also promised Beliebers that his tour will be magic.
"It's going to be really crazy. We have David Blaine working on it. My choreographer is inventive and really creative," he said.
The Baby singer added that he'll be showing off some fancy footwork: "All that's left is to nail those Jacko-esque dance moves. I've been in the dance studio literally every day getting ready."
