Brad Pitt and Angelina Jolie waved last night as they headed off to his Make It Right NOLA gala at the Hyatt Regency New Orleans. He organized a charity auction and bash to raise funds for the organization's ongoing efforts to build sustainable homes in the city's Lower Ninth Ward. Brad rounded up famous pals like Ellen DeGeneres, Rihanna, Aziz Ansari, and Kanye West for the event, which may have raised as much as $4 million. Speaking of the famous attendees, Brad was humbled they'd travel to Louisiana. He said, "They carved this time out of their schedule strictly for this event, and came on their own dime. We have so much incredible talent that wanted to come and support the city — it's going to be like a mini-Grammys show."
