London: Simon Cowell is obsessed with other men’s exes and has bedded his own brother’s and close pals’ cast-offs, a new book has revealed.
The music mogul’s ruthless attitude to sex left his brother and best friend fuming, according to The biography Sweet Revenge: The Intimate Life of Simon Cowell by Tom Bower.
His love for other men’s women has continued in recent years as one pal claimed: “Simon always goes after his friends’ ex-girlfriends.”
Sensational anecdotes in the book, which hit shops on Friday, detail how Cowell’s love for dating others’ exes started 30 years ago, the Daily Star reported.
Cowell famously enjoyed a romance with pop princess Sinitta, 48, and the book reveals she was first dating his brother Nicholas during a trip to their parents’ home in Mallorca.
“Sinitta travelled as Nick’s girlfriend to the island for a holiday. Shortly after, and not for the last time, Simon inherited one of Nick’s cast-offs,” the author said.
Years later Cowell is said to have struck again when Nicholas dated sexy Terri Seymour, 37.
The pair had known each other for over a decade and did not hook up until Terri enjoyed a love affair with his brother. Simon then had a drink with her and they started dating.
“Seymour had been dating his brother Nicholas before flying to Los Angeles to feature in an advertisement for shampoo,” the book revealed.
“She telephoned Cowell for a drink, unaware of his new fame. One week later, instead of returning to London, she moved into his house, hoping the relationship would lead to marriage and children,” it added.
Simon’s antics even left one of his long-term friendships in tatters.
He firstly enjoyed a fling with Mandy Perryment, who had been married to his best pal Iain Burton for five years. She was romanced by Cowell in London and Miami after her divorce.
But it was Cowell’s affair with Iain’s topless model girlfriend Vanya Seager that proved the final straw for him.
The pal heard of Cowell’s behaviour from Sinitta in an emotional phone call. She told Burton: “Simon’s been having an affair with Vanya for at least a year.”
She reportedly said to Iain: “Don’t you understand? He wants to be you.”
Iain later said: “Simon stabbed me in the back. In one go I lost the woman I loved and my best friend. They’re the two people I love most in the world. It’s so painful.”
And he admitted hearing the news left him “dumbstruck and unable to breathe”, adding, “It hit me like a thunderbolt.”
The book reveals he only proposed to lover Mezghan Hussainy after hearing another man wanted to marry her.
Pal Maurice Veronique said: “Simon always went after his friends’ ex-girlfriends because he wasn’t very good at picking up girls himself.”
However, a source close to Cowell said: “This is an unauthorised book.”
Meanwhile the ‘X Factor’ boss showed no signs of changing this week when he stepped out with divorcee Ana Paula Junqueira, 38.
The former wife of Brit businessman Johan Eliasch, 49, enjoyed a romantic time with Cowell after first meeting him on his yacht in January.
