Singer Sonu Nigam recently passed out, while shooting for a music video. The singer was shooting for a music video for Independence Day. He was suffering from high temperature but still insisted on shooting. He got so involved with the shoot that he kept on giving retake after retake. As soon as the shooting was finished, Sonu collapsed all of a sudden. He was taken to the hospital, immediately. It was also his birthday on the same day. But the celebration was called off, due to his state.
