There's nothing we love more than a secret celeb shag fest
The music mogul, who is currently penning his autobiography, told the journalist helping him write the thing: "I had a crush on her. It was Dannii's hair, the sexy clothes, and the tits."
Thankfully it wasn’t just Dannii’s breasticles (which are pretty amazing to be fair) that tempted Mr Cowell. He added: “"I was like a schoolboy. She was foxy. She was a real man's girl. Very feminine. It was genuine love."
Couple of points we’d like to mention here. Firstly - imagining Simon as schoolboy is weird. Secondly - the L word? Wowzer.
Although there’s been rumours that the two were lovers, Dannii, who is 12 years Simon’s junior, has previously denied any relationship. Sorry D, the cat’s well and truly out the bag now!
Yonks ago, she told the Sunday Mirror: "I don't fancy him and I don't have a type I go for, but I like a man who makes me laugh."
He may not have been making you laugh Dannii, but he certainly seems to have held some attraction! Was it the sexy chest hair or the super-high trousers?
Dannii - who sadly confirmed her split with long-term partner Kris Smith last week - is yet to comment, but somehow we don’t think she’ll be too impressed with the revelations.
All we can say is that if this is the kind of shiz we can expect from Simon’s autobiography, you can bet your bottom dollar we’ll be picking up a copy as soon as it hits the shelves.
What do you think about Simon and Dannii doing the nasty? Are you shocked?
