Hollywood star Brad Pitt recently joined singer Bruno Mars on stage for a rendition of 'Sex Machine'.
The 50-year-old Hollywood actor played tambourine and danced on stage as Mars sang the James Brown classic, reported Digital Spy.
The duet took place last week at Pitt's 'Make It Right' fundraising gala in New Orleans, where Sandra Bullock also made an appearance.
The singer can be heard introducing the star, announcing: "Make some noise for Brad Pitt."
The 'Treasure' hitmaker will continue his 'Moonshine Jungle' world tour later this week with a performance in Las Vegas.
