Chumlee -- I Got a Playstation in My TRICKED OUT Rolls Royce

"Pawn Stars" has been very VERY good to Chumlee ... 'cause the reality star hit the Hollywood club scene last night in a pimped out Rolls Royce ... complete with a VIDEO GAME system in the back.

A perspiring Chum was on his way out of MyStudio with some friends ... when he crawled into the back of the super-expensive ride ... grabbed a Playstation controller ... and gave us the play-by-play.

"We got FIFA going" ... Chum said ...adding, "It is what it is ... we play Playstation in the Rolls Royce!!!"
