The annual Royal Variety Performance took place this year at the Hammersmith Apollo in London, and featured performances from Robbie Williams and Lady Gaga.

LADY GAGA MEETS PRINCE CHARLES AND CAMILLA

Before the show, Gaga and Williams met with Prince Charles and Camilla. Camilla revealed that she and the “Bad Romance” singer have something in common – they are both nicknamed Gaga. “My grandchildren call me Gaga,” said the Duchess of Cornwall.

Gaga wore a silky off-white gown, and Camilla a red lace dress with sheer sleeves. Gaga and Williams performed alongside Sting and Emeli Sandé. The evening benefited the Royal Variety Charity, and featured performances from the Cirque Du Soleil cast of LOVEBritain’s Got Talent winner Lance Corporal Richard JonesAmber Riley, One Republic and DNCE, among others.

The show was hosted by Britain’s Got Talent judge David Williams. The Royal Variety Charity has only one sole patron – the Queen – who has attended 39 of the variety shows, but in recent years has left the honors to Charles and Camilla.
