After his unofficial memoirs caused shockwaves across showbiz circles, Simon Cowell is planning an official autobiography where he will divulge the truth about his relationships with Dannii Minogue and Cheryl Cole. Former co-stars Cheryl, 28, Dannii and Sharon ¬Osbourne, 59, were all said to be infuriated after details of their personal relationships with X Factor boss Cowell were revealed in Tom Bower’s ‘Sweet Revenge: The Intimate Life of Simon Cowell’. The king of reality TV warned his A-lister friends there would be more revelations to come. “There are records to set straight and scores to settle. If you thought Bower’s book was scandalous, it only scratched the surface,” the Daily Star quoted a source as saying. Simon brought out his own official autobiography in 2003 dubbed ‘I Don’t Mean To Be Rude, But’. And now he insists he wants to update his life story. In a wide-ranging interview, Simon spoke about this year’s BGT judges’ line-up, saying: “I really like the panel this year and would say it is the best line-up yet. David is a very, very funny man. He’s also really weird and that’s probably why we get on so well. Alesha has been a total star and I’ve always enjoyed working with Amanda.” However, he did confess that he was worried about controlling David in tonight’s live semi-final. When asked what he thought of past ‘X Factor’ and BGT line-ups he added: “I’m saving it for my book.”
