The 'Wolf Of Wall Street' actor celebrated his birthday at The Darby in New York and blew the huge amount on alcohol for his friends, reported Hollywood life.
"He and his crew spent USD 3 million on Armand de Brignac. They ordered 18 cases, then requested more bottles!," a source said.
While DiCaprio may have spent the huge amount, his party - which was attended by stars including Beyonce Knowles and her husband Jay-Z, Robert De Niro and Cameron Diaz - was in aid of a good cause.
The charitable star used the occasion to raise money for the Red Cross to help those affected by Hurricane Sandy by adding a fee to every bottle sold to be donated for charity.
