Dallas Mavericks owner Mark Cuban spent a whopping $110,000 while celebrating at the trendy nightclub Liv at Miami’s Fontainebleau after winning the NBA Championship against the Heat on Sunday night. Cuban spent $90,000 on an oversized bottle of Armand de Brignac Champagne for teammates Dirk Nowitzki, Brian Cardinal, Jason Terry and Shawn Marion in celebration of their victory, which they finished in a mere four hours. But that’s not all. When the bill arrived, Cuban left an additional $20,000 tip for the wait staff. According to Forbes, he’s ranked 459th on the “World’s Richest People” list and has a net worth of $2.5 billion.
