Chris Brown threw an enormous soiree to celebrate his birthday, but things got out of hand that police stepped in and pulled the plug.

Law enforcement received multiple calls about loud music and cars double-parked all over Chris' neighborhood in the San Fernando Valley. 

Police arrived the home Thursday around 2am and talked to Chris' security. 

According to sources, the music was turned down, but that also spelled the end of the shindig, which police estimated had between 400 and 500 guests in attendance.

Squad cars were seen all over the place directing a massive traffic jam as limos and fancy cars zig-zagged their way out.

Parking tickets were also issued to improperly parked cars.

A helicopter also hovered above the area, creating  more noise for neighbors trying to sleep.
