Queen Elizabeth II has spent 60 years putting duty above all else and last night was no exception, with the monarch cheerfully attending a pop concert to celebrate her Diamond Jubilee despite Prince Philip being taken to hospital just hours earlier.
The queen arrived at 9pm, and was met with deafening applause from the 500,000-strong crowd outside Buckingham Palace.
The monarch was joined by other senior royals including Prince Charles and Camilla, Prince William and Catherine and Prince Harry.
Prince Philip spent the evening in a nearby hospital receiving treatment for a bladder infection.
Prince Charles made a moving tribute to his mother at the event.
