Bobby Shmurda -- Drive-By Shooting at Nightclub Gig

Bobby Shmurda fans heard gun shots ring out early this morning during his nightclub appearance last night in New Jersey ... as a drive-by shooter opened fire.

Police say shortly before 2 AM ... someone driving out of the Club Eden parking lot in Roselle, NJ fired 2 shots ... and set off a chaotic mess. Three different police departments had to respond to control the crowd.

According to cops ... about 200 people were packed in the lot and became "unruly and agitated" when officers tried to clear the area.

Bobby was not there when cops responded. We're told no one was struck by the bullets.
