Holly Willoughby has revealed that Louis Walsh is the real Mr Nasty on The X Factor.
The presenter, 27, thinks he is far crueller that acid-tongued judge Simon Cowell.
‘Louis is outrageous and likes to bitch,’ she says. ‘He makes everyone laugh but he can be a bit mean to the contestants.’
She says Simon, 48, isn't as vain as he's made out to be.
‘I had heard that Simon was a bit of a diva, that he preened himself in the mirror a lot, but he's changed,’ she tells the Sunday People.
‘He isn’t like that any more. He's very hard working and is very encouraging to the panel.'
