Lady Gaga was spotted at The Radical Eye dinner for the Elton John Aids Foundation in London on Thursday night. Gaga, who arrived in the UK earlier this week ahead of her performance at the X Factor, looked gorgeous in a black Azzedine Alaia gown as she posed for photographers at the black tie dinner, hosted by Sir Elton John and David Furnish.

This special event took place on December 1st, the World AIDS Day. All money raised from the evening will benefit the Elton John AIDS Foundation. The Foundation funds frontline programmes that help to alleviate the pain of those living with, affected by or at risk of HIV/AIDS.
