Brad Pitt showed his generous side this past Saturday night as he held a charity gala at the Hyatt Regency in New Orleans.  The charity is called the "Make It Right" Foundation.  Brad co-hosted the event with Ellen Degeneres.

At the event, Rihanna and Kanye West were brought on stage to perform Run This Town, and the crowd loved every second of it.
