The Queen and the Duke of Edinburgh have attended the 84th Royal Variety Performance at Royal Albert Hall in London, in celebration of the 100th anniversary of the first Royal Command Performance held at London's Palace Theatre on 1 Jul 1912.
The Queen and Prince Philip attended the evening gala as a finale to the Diamond Jubilee year and on the night before their 65th wedding anniversary, which falls on 20 November.
The Royal Variety Performance witnessed performances by Robbie Williams, Girls Aloud, One Direction, Kylie Minogue, Alicia Keys, Neil Diamond, Rod Stewart, Placido Domingo and Katherine Jenkins.
"It's an honour. It does make you nervous when the Queen is watching you. You want to do your best," said Jenkins, who performed for the fourth time at the Royal Variety Performance, according to a BBC report.
Other performers included comedians Rhod Gilbert and Bill Bailey and 'Britain's Got Talent' winner Ashleigh and her performing dog Pudsey.
The show at the Albert Hall was followed by a star-studded after show party, champagne reception and banquet at the Hilton on Park Lane - as a unique celebration of Royal Variety Performance in its centenary year.
It was the 36th Royal Variety Performance for the Queen. She first attended the event in 1947 as Princess Elizabeth. The Queen arrived in a regal golden ensemble for the show and greeted, shook hands with performers of the evening.
All the proceedings from the event will be donated to the Entertainment Artistes' Benevolent Fund (EABF).
ITV which had won the broadcasting rights of the event for the next 10 years in 2011, would screen this year's event on ITV1, on 3 December.
