Are they? Aren't they? Is that an engagement ring on Mezghan's finger?  It was like watching a tennis match at Wimbledon when we heard the rumours about Simon and his girlfriend, Mezhgan Hussainy getting hitched.

But now, we can stop guessing because Simon's one true love confirmed to radaronline.com that he is going to make an honest woman out of her.

Yep, the original Mr nasty has finally decided to settle down after years of avoiding commitment.

Si's publicist Max Clifford has given the thumbs up over the union saying,

“The are very suited. She is someone who is independent and says what she thinks and feels and he likes that.”

Now, everyone knows that Simon Cowell doesn't do anything by halves, so we're jumping up and down with excitement about what Simon's wedding will look like.

A hundred tiered wedding cake? The world's famous pop stars performing at the reception? Star studded guest list? we don't know but we can't wait!
