Lady Gaga made a surprising appearance at the annual Royal Variety Show in London, UK earlier this month to perform her second single 'Million Reasons.' The show aired tonight on ITV and if you missed you can watch the full performance in HD below.

Back in December 2009, Gaga appeared for the first time wearing a red latex dress by Atsuko Kudo, inspired by Queen Elizabeth I and performed 'Speechless' from her album The Fame Monster in front of senior members of the British Royal Family.
