The singer, who fractured her left ankle in two places during dance rehearsals for Capital FM's Summertime Ball a couple of weeks ago, rose to the occasion, refusing to let the clunky cast get in the way of her stage presence.
We love her monochrome catsuit, chunky gold jewellery and artistic purple eye make up. But most of all we love her attitude - and we weren't alone.
The Essex-born star won the hearts of festival goers with her gutsy set on the Other Stage, we just hope her injury's not giving her too much pain today as a result.
