Cops swarmed the Grammy afterparty

Cops swarmed the Grammy afterparty thrown by Meek Mill in the Hollywood Hills — a party so wild it had more than a thousand celebs and actual WILD ANIMALS!!

Meek rented out a mansion on Mulholland Drive and hosted Diddy, Lil Wayne, Drake, Nicki Minaj, Birdman, Nelly, Jermaine Dupri, Bow Wow and many more — but the bash was still going at 5 AM … and that’s when the California Highway Patrol stepped in to shut it down.

TMZ sources inside the party tell reported that most of the guests were shuttled up to the mansion — but others parked illegally along Mulholland — and cops were towing cars as the sun came up.

Hundreds of guests were stranded, wandering the street trying to get home.
