Jay-Z threw a Miami bash for his new album, “Watch the Throne,” Sunday night at the Fontainebleau, and splashed out on a $100,000, 15-liter bottle of Ace of Spades Champagne, according to spies. “It takes two people to serve the Champagne due to the size and weight of the bottle,” remarked a gob-smacked witness. The dapper rapper partied without his wife, Beyoncé who was performing in New York at the Roseland Ballroom, or his “Throne” partner Kanye West, who was overseas, according to a Jay-Z rep. Instead, Jay-Z hosted a dinner for about 40 friends — including DJ Clue, Ne-Yo and Kim Porter — at Scarpetta before moving his bash to Fontainebleau club LIV, where the mega-bottle of bubbly got popped. Jay-Z references the Miami Beach resort — and Ace of Spades — in his “Throne” ditty “Primetime,” rapping, “I’m headed to Miami to [bleep] up the Fontainebleu, a case of Ace, make it two.” The club was decked out with artwork inspired by Riccardo Tisci’s “Throne” album cover.
