X Factor judge turns down bit part in comic show

An X Factor judge has turned down a cameo role in a TV comic show. Simon Cowell refused to play a bit part in Ricky Gervais's comic genius show Extras because he could not sing. The stern faced judge who slams singers week in week out on the Saturday night talent show was worried that his singing voice would not go down very well with the last episode. Other famous faces have appeared on the comic show including movie actor Robert De Niro.
