U.S. actor Will Smith and his wife Jada Pinkett-Smith introduce the 46664 concert in honour of Nelson Mandela in Hyde Park, London June 27, 2008. The event was organized to raise funds for Nelson Mandela's HIV/AIDS "46664" campaign, named after his prison number. Exactly 46,664 people were expected to attend the event, which also celebrates the former South African president's 90th birthday on July 18.
Stars of the screen, stage and sporting arena have paid tribute to Nelson Mandela, whose visit to London was overshadowed by events in Zimbabwe where disputed elections have just ended.
Hollywood actor Will Smith hosted a birthday celebration concert in front of Mandela, who turns 90 next month, and nearly 50,000 cheering fans in London's Hyde Park.
