Brad Pitt Dances, Plays Tambourine Onstage With Bruno Mars at Make It Right Gala

He's a sex machine, alright! Brad Pitt joined Bruno Mars onstage at the Make It Right Gala on Sunday, May 18, soulfully rocking out with a tambourine in front of a roaring crowd. "Make some noise for Brad Pitt!" Mars yelled as he greeted Angelina Jolie's man with a handshake and chest-bump.

"You might have seen him in Fight Club," Mars sang in the tune of James Brown's "Get Up I Feel Like Being a Sex Machine." The Grammy winner then rattled off a list of Pitt's hit flicks including Inglourious Basterds and The Curious Case of Benjamin Button.

"1-2-3-4! Brad Pitt you sexy motherf—er," crooned Mars, while Pitt, 50, tapped the tambourine. Eventually, the hunky father of six began hopping and arm-waving; turns out Pitt has pretty impressive dancing chops!

When he wasn't tearing up the stage with Mars, an observer at the event told Us Weekly that Pitt and his gorgeous fiancee Jolie "looked very happy and in love." The Maleficent actress, 38, attended the event to support her man's Make It Right foundation, which provides housing for those in need.

Other stars in the house to support his cause included Sandra Bullock (who gave a graduation speech locally several days later), Sofia Vergara, Chris Rock, and Pitt's late-night party pals, Kings of Leon! "Bruno Mars and everyone was happy to lend their time to help the cause," another source told Us. "Brad thinks [comedian] Jim Gaffigan is hilarious, and was a great booking for the event."

The insider added that the father of six was "incredibly happy to be back in NOLA and present his charity event again. He tries to do at least one a year and reconnect with everyone he's tried to help."

Altogether, Pitt's weekend in New Orleans was eventful. Jolie's fiance created a frenzy when photographers captured him tossing a beer from his balcony to Matthew McConaughey (who was hanging out with Saints quarterback Drew Brees) on Saturday, May 17. "Brad loved seeing Matthew," the insider explained. "They weren't aware that their events were happening around the same time, initially."
