Brad Pitt enlisted the help of pop phenom Rihanna to perform at his charity gala held in New Orleans Saturday night. Pitt’s Make It Right foundation is a post- Hurricane Katrina cause that “builds safe, sustainable and affordable homes for working families. We aim to be a catalyst for change in the building industry in New Orleans and beyond.” Check out some pics of RiRi on stage below. Looked like a successful event! Wendy L.
