Simon Cowell and Dannii Minogue were sharing more than the 'X Factor' judges table, according to a book on the music mogul.
In the new book from journalist Tom Bower's titled 'Sweet Revenge: The Intimate Life Of Simon Cowell', the writer says that the two were involved in a secret affair while filming the talent competition.
"Simon was furious at first when he found out that I had found out about the relationship," Bower says in an interview.
Asked if Cowell eventually confirmed the romance, Bower replied: "Yes, he did."
There are several quotes from Cowell speaking about the romance in the book.
"I had a crush on her," Cowell says. "It was Dannii's hair, the sexy clothes and the t-ts. I was like a schoolboy. She was foxy. She was a real man's girl. Very feminine."
"There were a few bonks and then it petered out while I was in America."
Asked if Cowell had seen the book, Bower said: "Simon has not read the book, he has not seen any of the text and he won't be able to read it until it goes on sale."
Meanwhile, shortly after the interview the judge took to his Twitter page to say "just seen the TV ad for the unauthorised book on me. Yikes!'"
