Xtra Factor host, Holly Willoughby, has revealed that X Factor judge Louis Walsh loves to bitch and that Simon Cowell doesn’t preen as much as one might think.

She told the Sunday People: “Louis is outrageous and likes to bitch. He makes everyone laugh but he can be a bit mean to the contestants.”

On the subject of Simon Cowells vanity she said: “I had heard that Simon was a bit of a diva, that he preened himself in the mirror a lot, but he’s changed.

“He isn’t like that anymore. He’s very hard working and is very encouraging to the panel.”
