Simon Cowell has decided to cancel his engagement to make-up artist Mezghan Hussainy after quickly realizing she wasn’t the one.

In a new biography of the music mogul, it was revealed that Simon Cowell cancelled plans to marry the stunning Afghan some time ago and plans to give her his $8 million Beverly Hills home as a generous parting gift.

Soon after their February 2010 engagement, Mezghan Hussainy reportedly became upset over Simon Cowell’s busy lifestyle and his relationships with his circle of close female friends.

Simon Cowell has famously remained friendly with ex-girlfriends Jackie St. Clair, Sinitta and Terri Seymour, even buying the latter a $4.6 million house in Los Angeles following their split in 2008.

The pair soon started arguing frequently with the Britain’s Got Talent judge soon realizing he’d made a mistake by asking her to marry him.

Friends of Simon Cowell speak of his embarrassment at realizing he didn’t want to marry Mezghan Hussainy in a new unauthorized biogaphy, Sweet Revenge: The Intimate Life Of Simon Cowell by Tom Bower.

After Simon Cowell returned home late from an American Idol taping one night in 2010, furious Mezghan Hussainy lashed out at him, in front of his mother Julie, 87.

Julie Cowell is quoted as saying: “The tension was horrendous. The way Mezhgan behaved made my stomach churn.”

After Mezghann Hussainy apparently stormed out, his mother said: “Something’s wrong here Simon. It’s not what we thought. I was very happy and now I’m not.”

Simon Cowell admitted they were having issues: “There’s a problem.”

He soon admitted to his friends he’d made a “big mistake” and decided to move into the Peninsula Hotel in LA, rather than share a roof with her.

Simon Cowell eventually admitted to Mezghan Hussainy there was no future for them, but declined to make a public announcement to that effect.

Simon Cowell was last photographed with Mezghan Hussainy last September leaving a friend’s house in Beverly Hills.

She wasn’t wearing her engagement ring at the time and Simon Cowell’s spokesperson Max Clifford said: “Well I don’t know about planning a wedding – I think you might have to wait 20 years for Simon to plan a wedding but they are as close as they’ve ever been.”

In an interview last September, Simon Cowell said: “I’m not going to lie, everything this year has been about working on The X Factor. It has probably been the busiest year I’ve ever had.

“Making the choice to get married is something you just have to decide when the time is right.”

Simon Cowell and divorcee Mezghan Hussainy met while she was a make-up artist on American Idol.

They got engaged on Valentine’s Day 2010 at Simon Cowell’s West London home, when he proposed with a $400,000 diamond ring from jewellers Graff.

The new book claims Simon Cowell started seeing Mezghann Hussainy in 2006, when he was still living with ex-girlfriend, TV presenter Terri Seymour.
