Justin Bieber really needs to tone it down with the house parties, or he could get into even more serious trouble next time around. 

Apparently over this past weekend, the cops got called to his house SIX times because of noise complaints. That's a lot.

Luckily, nothing broke the rules for his probation, which was good. But if he keeps it up, he could be paying some serious penalties for breaching probation.

I wonder if he'll learn. Then again, based on this recent Instagram post, I'm not sure he will...
