While Jay-Z is promoting "Watch The Throne," he's also watching his bar tab. The New York MC partied quite heavily at Miami's LIV club in celebration of his joint album with Kanye West and reportedly spent $250,000 on liquor, champagne of course.

“Jay knew that Mark Cuban spent over $100,000 after the Mavs won the championship a few months ago, and he wasn’t about to be upstaged,” a source close to Jay-Z told RadarOnline.com.

“He bought bottle after bottle of Ace of Spades and then went all out with the 15-liter bottle that cost $100,000 on its own!” the source continued. 

Word also says that Jay-Z left a sizable $50,000 tip for the waiters when he left.
