Cheryl Cole set to reveal all on The X Factor and Simon Cowell in her autobiography

Cheryl Cole’s autobiography will reportedly spill the beans on The X Factor and Simon Cowell, rather than her personal life with ex-husband Ashley Cole.

According to tabloid reports, Cheryl has been banned from dishing too much dirt on her personal life by Ashley’s lawyers, following the pair’s divorce last year.

“Cheryl won’t be writing much at all about her marriage,” a source told The People yesterday. “She will be penning her opinions about her and Ashley but there will be no more sordid revelations. Her fans might have been hoping for some real fireworks and her laying into Ashley but it won’t be happening.”

The source explained: “Instead she will be concentrating on her working life, her time with Girls Aloud and her years on The X Factor.

“The fact that there will be little focus on Ashley doesn’t mean the book won’t be a brilliant, entertaining read. It will be Cheryl’s life, from her tough upbringing to her global fame.”

And after revelations in his own book, Simon Cowell is said to be “fair game” for comment from Cheryl.

The source added: “There’s no doubt that Simon Cowell will come in for a bit of a kicking after what he said about her in his biography.

“There is no way that Simon will come out of this unscathed. He’s fair game to Cheryl after what he allowed to be written about her.”
