PR pro Max Clifford has told Exclusive TV that Simon Cowell did have an affair with co-judge Dannii Minogue in 2008 as alleged in Cowell's unathorised biography.
The Intimate Life of Simon Cowell penned by Tony Bower claimed that Simon embarked on a romantic affair with Aussie star Minogue while filming the X Factor four years ago, a claim that has been validated by Clifford who said: "Yes - he did have a relationship with Dannii.
"Simon was on his own at the the time and she was on her own too. There was a natural chemistry between them.
It's not something he wanted to come out but it has - there is nothing unusual about it at all."
Meanwhile Simon's fellow judge on Britain's Got Talent, comedian David Walliams has been quick to mock the revelations on Twitter: "Now I know why Simon Cowell would sometimes ask me to dress up as Dannii and sing 'This Is It' when we're making love," he Tweeted.'
