Simon Cowell felt "genuine love" for Dannii Minogue and the pair had a love affair four years ago, according to a new unauthorised biography.
As reported in The Sun On Sunday, in the book entitled The Intimate Life Of Simon Cowell, written by former BBC journalist Tom Bower, the media mogul apparently confesses all and admits to feeling "like a schoolboy" around the Australian singer.
The fling was alleged to have taken place in 2008 before Dannii got together with Kris Smith and after Simon split from long-term girlfriend Terri Seymour.
Bower, a former Panorama reporter who is noted for his investigative work, alleges that Dannii became Simon's target when she joined The X Factor judging panel in 2007. In the book, Simon apparently says: "It was genuine love."
However, both stars denied having an intimate relationship at the time after pictures emerged of them looking close.
The book also claims that Cowell attempted to sleep with Natalie Imbruglia last year.
