SIMON Cowell had a sensational secret affair with X Factor judge Dannii Minogue, The Sun revealed on Sunday.  The TV mogul, 52, confessed they were lovers when they worked on the show. He admitted: “I had a crush. It was genuine love.”

The astonishing revelations are made in a book published next month called Sweet Revenge - The Intimate Life of Simon Cowell, by acclaimed biographer Tom Bower.

The blockbuster, exclusively serialised in The Sun this week, also tells how Cowell planned to attract Dannii’s friend, singer Natalie Imbruglia, just last year after inviting her on to his yacht. It reveals how Cowell “fell in love” with Dannii, now 40 and a mum of one.  This month Dannii - on The X Factor from 2007 to 2010 - split from Kris Smith, 33, after four years. Then Cowell became obsessed with Cheryl, 28, when she joined the show. He moved her to sit next to him on the panel.        –The Sun
