Kate Moss was a surprise celebrity guest in the audience at The X Factor on Saturday night, there to watch Britney and the contestants do their thing! While hanging out backstage the supermodel bumped into Eoghan Quigg and lent him her jacket as he was cold, but — bless him — he didn't even realise who she was. He twigged eventually, but who'd have thought that Kate Moss would be a fan of reality TV. As she left in a car she looked relaxed and happy, it seems everyone's got X Factor fever at the moment!
