Chris Brown -- Crowd Swarms Lambo ... Ragin' Against the Machine

Chris Brown's crew got into a scuffle Friday night with an out-of-control crowd outside a Hollywood club, with Chris smack in the middle.

Chris went to Argyle nightclub in Hollywood after his concert at the Palladium, and as he left the club in his Lambo someone knocked a cellphone out of the hand of one of Chris' friends. That was enough to draw a crowd that got unruly as a frustrated Brown tried to drive off.
