Pauly D -- New Liquor Deal Could Make Him CRAZY RICH!!!

"Jersey Shore" star Pauly D is entering the liquor business ... and TMZ has learned his new signature drink deal could set him up for life.

According to our sources, Pauly D is close to announcing his own ready-to-drink cocktail called REMIX ... a series of vodka-based drinks in various flavors. Pauly's drink is meant to target the "pre-game" market -- the kind of drink you have before you go out for the evening.

Our sources say Pauly D's business partner is none other than David Kanbar, the co-Founder of Skinnygirl Cocktails. We're told the drink was brought to the Wine & Spirits Wholesalers of America convention in Las Vegas early last month and buyers loved it.
