The Daily Telegraph reports
Simon Cowell admits he was for years in "genuine love" with Dannii Minogue - even remodelling the panel of his UK show The X-Factor to be closer to his co-star - claims a controversial new biography on the TV tycoon.
Quotes from the music mogul saying he was "like a schoolboy" staring at "her tits", coupled with Minogue's recent split from partner of four years Kris Smith, have led to rampant reports the pair were having an affair.
Written by former BBC journalist Tom Bower, a major chunk of The Intimate Life Of Simon Cowell centres around the 52-year-old multi-millionaire's infatuation with Minogue ("She was foxy. She was a real man's girl. Very feminine," he said) but does not feature any confirmation they engaged in any kind of relationship.
Rumours that the pair were together first surfaced in 2008 - before Minogue met Smith in September of that year - following the publication of a grainy photograph that appeared to show them holding hands in the back of a car.
At the time Minogue denied the suggestion, saying: "We were not holding hands. But no one believes me. It was the angle of the picture."
Minogue - who finished up working with Cowell on The X-Factor in 2010 - refused to comment on the tome yesterday when Confidential contacted her people.
Over the years Cowell has forged a reputation for going to great lengths to court women - fellow Australian Natalie Imbruglia said to be one of the more recent - and then losing interest.
