Justin Bieber had the cops called on him three times in one night because of a way-too-loud party this weekend, but he doesn't seem too upset about it.

The Biebs hosted a rager on Friday night (Nov. 15) with over 100 people in his Calabasas, Calif. mansion, including Snoop Lion. Bieber's neighbor -- the same one whose face he allegedly spit in -- called the cops around 1AM, when sheriff’s deputies went to the mansion and asked them to keep it down.

Around 3AM, the same neighbor called the cops again. Still, the noise continued, and at 5:30AM the neighbor not only called the cops one more time, but also filed a police report saying that Biebs was disturbing the peace in their otherwise quiet gated community. (The neighbor also said cops smelled weed, but that no one was arrested.)

When TMZ cameras caught up with the 'All Bad' singer, he didn't express any remorse -- or information -- about the shindig. He did, however, say, "You shouldn't have missed it. It was wild. It was wild! It was some 'Great Gatsby' s---."

Too bad Bieber's neighbors don't appreciate him being young and beautiful ... because he's also young and loud!
