In what could be called as a lavish fight, a pair of rival billionaires set a new world record at a French nightclub to see who could order the most champagne.

Zhen Low – the younger brother of big-spending Malaysian billionaire Jho Low – squared off against Winston Fisher of the prominent New York real-estate family Thursday night at Les Caves du Roy nightclub in St. Tropez.

The bill? A staggering 2 million euros, or $2.6 million, according to an announcement made at the club.
