LEONARDO DICAPRIO threw himself a 38th birthday party in New York City on Saturday.  But it wasn't all about him.  The party doubled as a fundraiser for Hurricane Sandy victims.

Guests included Jay-Z, Beyoncé, Cameron Diaz, Emma Watson, Chris Rock, Martin Scorsese, Robert De Niro, Edward Norton, Jamie Foxx and Jonah Hill.

By the end of the night, they had raised $500,000.
