His recent engagement to American Idol make-up artist Mezghan Hussainy ended weeks of speculation about his relationship with the Afghan-born beauty. The couple are expected to get married later this year.
What does Hussainy, 36, have that the others don't? Only Cowell, 50, can answer that.
According to Cowell's UK rep Max Clifford, Cowell and Hussainy "are very suited". She is independent and speaks her mind. And the sharp tongue Cowell "likes that". They have known each for a long time and began dating last year.
Other reports note that Cowell is a lot happier these days. Is that why his criticisms of contestants on this season's American Idol seem softer? Cowell continues to offer comments of aspiring idols' singing abilities in his usual acerbic style but sounds less harsh somehow.
If I am feeling generous, I would say that his recent remarks were tempered with compassion. Now I know why. Hussainy is making the wealthy Brit very happy. He is even talking about starting a family.
When did the light bulb pop for Cowell? I really would like to know his "aha" moment when he realised that "this is it".
People marry for various reasons not all of which are romantic. Men and women have been known to tie the knot for convenience, money or fear of growing old alone.
What is your reason, Cowell? His mother, according to The Inquisitr, was "delighted" but "shocked" when her son told her that he was planning to settle down.
Still, it is reassuring to know that Cowell is not the confirmed bachelor that he appeared to be. It is said that everyone has a soulmate. Apparently Cowell has found his.
