Justin Bieber -- Cops Called For Disturbing the Peace

Justin Bieber threw a rager last night and the neighbor with whom he has been at war called the police 3 times ... TMZ has learned.

Justin hosted a wild shindig at his Calabasas home for approximately 100 people including Snoop Lion. Apparently the noise was too much for some of the residents and cops were called at around 1 am.

We're told the L.A. County Sheriff's Deputies spoke to someone inside, told them to keep the noise down and left.

The noise didn't stop. At around 3 am Justin's next door neighbor -- the guy who Justin allegedly spit on during a prior altercation -- called again and deputies came out a second time. The neighbor tells TMZ cops told him they smelled marijuana inside but left without arresting anyone.

At 5:30 am the neighbor couldn't take it anymore ... deputies came out a third time and he filed a police report against Justin for disturbing the peace.
