Cheryl 'Won't Tell All About Ashley Split In New Book'
Sources claim there will be no 'sordid revelations' regarding their divorce...
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.”
