Simon Cowell Had Affair With Dannii Minogue

In his unauthorised biography entitled Sweet Revenge: The Intimate Life Of Simon Cowell, Bower claims that Simon and Dannii enjoyed several nights together during their time as X Factor judges.

It is also reported that Cowell tried his luck with Minogue's fellow Aussie Natalie Imbruglia, but that she gave him nothing more than a kiss and a cuddle and that his true affection lay with Dannii. 

'I had a crush on her. It was Dannii’s hair, the sexy clothes, and the t**s,' the music mogul is quoted as saying. 

'I was like a schoolboy. She was foxy. She was a real man’s girl. Very feminine. It was genuine love.' 

Referring to his ex-girlfriend Terri, Cowell goes on to say that his relationship with Dannii wasn't a serious one: 'After Terri Seymour, I wasn’t ready for another relationship.'

After Dannii joined the panel of The X Factor in 2007, rumours surfaced that she and Simon might be seeing each other behind closed doors and the pair were pictured holding hands in the back of a taxi after Children In Need that year.

And Simon's on-the-record praise of Dannii was telling, too, as he described the new judge as a 'sex symbol' when asked if he was pleased with his new recruit. 

'Every guy in the world fancies Dannii,' he said in 2008. 'She's become a sex symbol since joining the show, and the contestants love her. She's got that Sophia Loren, movie-star sex appeal, I love sitting next to her.'

Dannii, meanwhile, seemed more scathing of Simon, but an underlying chemistry was evident from the way she spoke about him.

'That man could flirt with a book, a wall, anything,' she said at the time. 'I don’t fancy him and I don’t have a type I go for, but I like a man who makes me laugh, who’s intelligent and speaks his mind.'

The relationship between Dannii and Simon is partly what caused the breakdown in communications between Dannii and Sharon Osbourne, according to Bower.

Osbourne left The X Factor at the end of its 2007 series after her public spat with Dannii.

A source told the Sunday Mirror today: 'Simon and Dannii always had a big on-screen chemistry, when Dannii joined the panel in 2007, but clearly managed to hide their affair from viewers. 

'They are said to have spent several nights together, but the ­relationship petered out after a while.'
