Snoop Dogg -- Promoter Sued for $115k Over Botched Appearance

Snoop Dogg's name (we refuse to call him Snoop Lion) is being dragged into a nasty lawsuit between a promoter and some nightclub -- all over an appearance gone wrong -- and now, the club wants over $100,000 in damages.

Exchange LA -- the nightclub in question -- filed a lawsuit in L.A. against a promotion company called Movement Management, claiming Movement promised to book Snoop for an appearance on June 30th ... for a fee of $25,000.

Exchange claims it paid a $15,000 deposit to secure Snoop -- but days after making the payment, Movement said Snoop had been double-booked ... and couldn't make the June 30th appearance as previously promised.

(For the record, Snoop was in Europe at the time.)

Exchange says it asked for its money back -- but it's been months ... and Movement still hasn't coughed it up, so now Exchange is suing for breach of contract and fraud.

Exchange wants its $15,000 deposit back stat -- in addition to $100,000 in punitive damages.
