Leonardo DiCaprio knows how to throw a party – with purpose!

The actor celebrated his 38th birthday on Saturday in the name of charity.

Beyoncé Jay-Z, Cameron Diaz and Emma Watson were among the guests at the Wolf of Wall Street actor’s birthday festivities at The Darby in New York.

The event raised money for the Leonardo DiCaprio Foundation and the charities it supports, which include direct donations to Superstorm Sandy relief.

Live performances by Gary Clark Jr. and ELEW kept guests – including Martin Scorsese, Robert De Niro, Chris Rock, Edward Norton, Jonah Hill and Jamie Foxx – on their feet throughout the evening.

Ultimately, the bash raised $500,000 for the American Red Cross.
