The music mogul is penning the book with the help of a writer, and judging from his comments, previous ‘X Factor’ stars who've misbehaved should probably be a little worried.
“This year’s ‘X Factor’ has been brilliant, both Fleur East and Ben Haenow have been a pleasure to work with,” he tells The Mirror. “As someone has already hinted, by the final stage of the competition, monsters do emerge.
"We have had our fair share. That goes in the next book.”
The book comes after Tom Bower’s 2012 biography, which, at the time of publication, left Si less-than-impressed, however he seems to have changed his mind.
In the years since Tom’s book, Simon has returned to ‘X Factor’, and also fathered a child with his girlfriend Lauren Silverman.
