VIDEO: George Clooney Duets With Neil Diamond

At last night's 'Carousel of Hope' charity event, actor George Clooney and legendary crooner Neil Diamond teamed up for a duet of "Sweet Caroline." Watch their musical moment below!

Prior to the 'performance', Diamond shared with the crowd that Clooney was insecure about his singing abilities. "He told me that people think just because I'm related to Rosemary Clooney that I can sing as well,' explained the singer, who later revealed that the actor had pleaded, "whatever you do, please don't ask me to sing." Lucky (or unlucky?) for the those in attendance, Diamond did not keep his promise!
