Simon Cowell Talks About His 'Complicated Relationship' With Mezhgan Hussainy

Onto the list of ways in which the outspoken judge of The X-Factor, Simon Cowell, is unusual, you can now add his relationship. While Cowell, 52, has been engaged to his makeup artist girlfriend, Mezhgan Hussainy, 38, since February 2010, he's now admitting that their on-again, off-again bliss might be off-again for the moment, and — what's more — it could stay that way.

Cowell, who is openly uncomfortable talking about his personal life, approaches his relationship with the same candor with which he seems to consider his job. Though he saw Hussainy over Christmas, they are not currently together. "It's quite a complicated relationship," he told the U.K.'s Daily Mail. "We have had a break from each other, and we are still incredibly close," he said.

In the past, Cowell feels like he has revealed too much about his relationship, as when he called Hussainy "the one" on Piers Morgan's show last year. "I have been pretty good about not talking about my private stuff, but I got caught up in the moment. I don't really know where I am at the moment, and that is why I don't talk about it," he clarified.

In keeping with that sentiment, Cowell was extremely vague about the future of his relationship with Hussainy, who has moved out of his L.A. mansion, according to the New York Daily News. "I'm vulnerable," he admitted. "It's not on, it's not off, it's somewhere in the middle," he said. "I don't know if I will ever get married, but I am happy."
