Louis Walsh's forthcoming autobiography will include a no-holds barred assault on Simon Cowell, it has been revealed.
According to the Daily Mirror, Walsh will devote entire chapters of the book, out in October, to lampoon the man who dropped him from the X Factor's judging panel.
The 54-year-old will even coax fellow judge Sharon Osbourne to join in, the tabloid claims.
"One of the chapters has the working title 'Never trust a man in heels!' It is poking fun at Simon's height and also how he likes to be pampered at the X Factor," a source told the Mirror.
"He will definitely try to knock Simon down a peg or two and is going to give it to him both barrels."
But a spokesman for music mogul Cowell hit back by saying: "We can't wait to read his version of events."
Walsh can now be seen on BBC1's Any Dream Will Do, passing judgement on aspiring singers angling for the lead role in Andrew Lloyd Webber's Joseph and the Amazing Technicolour Dreamcoat.
