Jigga didn't spend years of his life hustlin' just to be cheap with his money. Jay-Z had a release party for Watch the Throne at Miami's Fontainebleau yesterday where he spent a reported $250,000 on Armand de Brignac champagne and an additional $50,000 on a tip!!!!!!!!!!!!!!

"[Jay-Z] spent thousands more at Scarpetta, the Italian restaurant inside the hotel which stayed open extra-late for his crew. After a pasta dinner the rapper headed to the LIV Nightclub to continue the party."

That's enough to make my little head spin. A quarter of a million dollars spent on champagne and some lucky jerkoffs were paid $50,000 in tips!

"Jay-Z was well-behaved and laid low all night on a banquette with his entourage of boys," a source tells us.
