How to impersonate Simon Cowell: 'be a d**k', he says

Simon Cowell has told Nigel Harman to "be a d**k" to portray him accurately in 'I Can't Sing!'.
The former 'EastEnders' actor will play the 53-year-old music mogul in the upcoming 'X Factor' musical, and while Simon has tried not to get involved in the content of the production, he believes the 'Downton Abbey' star should act like a fool to ensure his portrayal is true to life.
