Brad Pitt surprised the audience at a charity fundraiser when he joined Bruno Mars on stage to play tambourine.
The Fight Club star was caught "shaking his money maker" on video at the Make It Right fundraising gala in New Orleans Saturday, when he joined Mars for a performance of a James Brown cover.
"I love New Orleans...And I'm extremely proud of the Lower 9th Ward community," Pitt told the cheering crowd.
The event was in aid of the post-Hurricane Katrina redevelopment, which was marking the completion of the 100th house.
Comedian Jim Gaffigan and indie band Kings of Leon also performed live at the second annual benefit.
Sandra Bullock later joined the 12 Year A Slave star on stage to host the fundraiser's live auction, which raised more than $4 million.
Pitt and his fiancée Angelina Jolie were seated together at one of the $2,500 ticket tables with the emcee for the night Chris Rock.
The 12 Monkeys actor will next play 'Wardaddy' in WWII flick Fury with Shia LaBeouf, Scott Eastwood, and Michael Peña.
Bruno Mars will next take his Moonshine Jungle Tour to California's Save Mart Centre in Fresno on Tuesday with opener Aloe Blacc.
