230SCowell051311_05_X17.jpgShe's been MIA throughout his entire St. Barth vacation, so it comes as no surprise that Simon Cowell and fiancée Mezhgan Hussainy have decided to put the breaks on their engagement, for now.

The X Factor judge claims they haven't been in contact in nearly a month, telling the Daily Mirror:

    “It’s quite a complicated relationship. We have had a break from each other, and we are still incredibly close. I’m vulnerable. It’s not on, it’s not off, it’s somewhere in the middle. I don’t know if I will ever get married, but I am happy.


That pretty much says it all!

The pair first met on the set of American Idol back in 2003 while she was doing his make-up, and Cowell proposed in February 2010 with a $500K diamond engagement ring. But breakup rumors began to spread when Simon was spotted getting cozy with a mystery brunette, and ex-girlfriend Sinatta, during a 25-day vacation on a rented yacht in St Barth.

The American Idol boss also revealed that he may have gone a bit overboard when he confessed that Mezhgan was "The One" on Piers Morgan's CNN show, telling the Mail, "I got caught up in the moment."

Mezhgan has moved out of Cowell's LA mansion and into another home he owns, which has earned the nickname “girlfriends’ graveyard,” after ex Terri Seymour stayed there during their 2008 split.
