Excuse us while we pinch ourselves, because we still can't believe that this actually happened. Just in case you thought that Brad Pitt was only in New Orleans to bro out with Matthew McConaughey, he was actually there to host the Make It Right Gala, a charitable organization that helps to build homes to those in need. And in addition to his hosting responsibilities, he also shared some serious stage time with Bruno Mars for a cover of James Brown's 'Get Up (I Feel Like Being a) Sex Machine'.

"Make some noise for Brad Pitt!" Mars screamed into the mic as the Oscar-winning actor took the stage to thunderous applause and cheers from the audience. As Mars absolutely killed a rousing rendition of the James Brown classic, Pitt played a pretty mean tambourine, jingling and clapping the instrument -- and even taking it to the floor during a particularly heated jam session. Work it, Brad! And don't just take our word for it: check out the video above!
