Justin Bieber is at war with a disgruntled neighbor once again. The same neighbor who called the police on the 'Baby' singer for allegedly spitting in his face filed a report with the boys in blue on Bieber for disturbing the peace. What happened?

TMZ reports that Biebs threw a massive bender with over 100 people crammed into his Calabasas, Calif. home -- including Snoop Lion. Someone nearby called the cops around 1AM, at which point sheriff's deputies went to the mansion and asked them to pipe down.

But they didn't.

Around 3AM, the same neighbor who Bieber allegedly battered previously called the cops again. He told the site that police went to the residence once more and that they smelled marijuana, but didn't arrest anyone. Still, the noise continued, and at 5:30AM the neighbor not only called the cops yet again, but also filed a police report saying that Biebs was disturbing the peace in their otherwise quiet gated community.

The District Attorney will review the report and decide from there whether or not to prosecute the boy wonder.

It's unclear whether this neighbor really has it out for Bieber -- which he may, considering he runs to TMZ whenever something happens -- or whether Biebs really is 'All Bad.'
