The Weeknd: Grammy Party Shut Down by Cops

The Weeknd ended his Grammy night with a face-to-face convo with police officers -- who came to toss everyone out of his massive party.

GQ hosted the bash in a Bev Hills mansion to toast The Weeknd's 2 Grammy wins and his birthday, and the party -- about 1,000 strong -- was rolling along until 1 AM. Law enforcement sources tell us multiple neighbors had enough and called police to complain about loud music and crowd noise.

We're told LAPD officers showed up around 1:30 AM, and we're guessing Weeknd drew the short straw since he spoke to the officers. It took police about 3 hours to clear all the fabulously dressed guests -- chicks in high heels move very slowly downhill.

Weeknd was totally cool with cops. Probably wanted everyone out anyway. Did you see Bella Hadid? Just sayin' ...
