When Jay-Z parties … Jay-Z parties BIG.

At Liv nightclub this past Sunday night in Miami, the Hip-Hop mogul celebrated his “Watch the Thorne” album success with friends by spending around $300,000!!!

A source from Jay’s camp told RadarOnline.com, “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. 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!”

To break it all down … the rapper spent about $250K on champagne, and tipped wait staff a further $50K, which is a pretty damn good tip if you ask us!

Jay has a reason to be a happy man though, and we’re sure he’ll make all of that money back and then some in due time. It’s being reported that his collaboration with Kanye has broken a record on iTunes already for the most downloaded album during its first week of release.

And have you seen the prices for those “Watch the Throne” Tour tickets? AND THE SHOWS ARE SELLING OUT! (Yikes!)
