A Diamond Jubilee is a celebration held to mark a 75th anniversary, but only the 60th anniversary in the case of a monarch (e.g. length of time a monarch has reigned). Traditionally, the diamond jubilee or anniversary of a person was also on the 75th anniversary. This changed with the diamond jubilee of the British Queen Victoria's reign. There was considerable national unrest when Queen Victoria largely withdrew from public life after her husband's death in 1861. It was decided to bring the diamond jubilee forward to the 60th anniversary in 1897. The diamond jubilee has been held on the 60th anniversary ever since.

The Diamond Jubilee of Queen Elizabeth II, to be celebrated in 2012, would be only the second in the country's history.

Robert Peter "Robbie" Williams (born 13 February 1974) is an English singer-songwriter, vocal coach and occasional actor. He is a member of the pop group Take That.

Williams rose to fame in the band's first run in the early- to mid-1990s. After many disagreements with the management and certain group members, Williams left the group in 1995 to launch his solo career. On 15 July 2010, it was announced he had rejoined Take That and that the group intended to release a new album in November 2010 which became the second fastest-selling album of all-time in UK chart history and the fastest-selling record of the century.

Williams has sold over 70 million records worldwide, which ranks him among the best-selling music artists worldwide. He is the best-selling British solo artist in the United Kingdom and the best selling non-Latino artist in Latin America. Six of his albums are among the top 100 biggest-selling albums in the United Kingdom. He has also been honoured with seventeen BRIT Awards—more than any other artist—and seven ECHO Awards. In 2004, he was inducted into the UK Music Hall of Fame after being voted as the "Greatest Artist of the 1990s."
