British singer Paloma Faith was left stunned during a performance at a posh party on Wednesday night (22May13) when one of the wealthy revellers tried to storm the stage. The pop star was headlining act at the Waitrose summer party at the Natural History Museum in London, which attracted guests including Catherine, Duchess of Cambridge's sister Pippa Middleton and celebrated chef Heston Blumenthal. However, Faith was shocked when business tycoon Sir John Madejski stumbled onto the stage while she was singing, before being dragged away by security guards. After the event, Faith said, "It must have been all the free champagne. Thank God I'm from (London area of) Hackney because I don't fear anything. I didn't flinch. I've seen worse and done worse."
