One Direction, Justin Bieber Collaboration: Jam Session Disturbs British Neighbors (PHOTOS)

One week ago Justin Bieber and One Direction were competing for several awards at the 2012 MTV VMA on Thursday, Sept. 6.

A week later Bieber and One Direction's Niall Horan hung out at Horan's apartment in the UK for a late night jam session on Wednesday, Sept. 12.

The pop singers' gathering in the wee hours of the morning became so exciting, the pair irritated Horan's British neighbors.

While Beliebers and One Directioners would love to experience being part of a gathering between America and Britain's biggest teen senstions, Hanson's neighbors felt otherwise.

"Think we p****d people off a little bit," the Canadian pop singer reportedly told Metro.

"We were making a little jam session at three in the morning and he lives in this apartment," he adds. "So there's people underneath him and we were playing really loud and all the sudden we heard "bang, bang, bang" on the door and this guy shouted 'keep it down.' It was crazy."

As for why the pair might have made too much noise when they met up to create possible music collaborations, Bieber explained, "We have a great time together."

Justin Bieber went to Europe to promote his new book "Just Getting Started" at a secret London location to meet his fans.

The "Biebs" is back in the US to appear on the season finale of "America's Got Talent" when it airs live on NBC on Thursday, Sept.13.

"make sure to watch TONIGHT when me and @bigsean hit the stage to perform on AMERICA's GOT TALENT @nbcagt," tweeted Bieber.
