Anna Kournikova

The former tennis player/model Anna Kournikova and the Latin pop sensation Enrique Iglesias make for one of the world’s strangest celebrity couples. Not because they don’t look good together, but mainly because they don’t give away the slightest detail about their personal lives.

To this day, the best evidence we have that Kournikova and Iglesias are hitched is the fact they have three children together and that Kournikova was once spotted with a $2.5 million ring. Kournikova insists that she’s not a fan of the idea of marriage, believing that you don’t love someone more “because of a piece of paper.” But what about a gorgeous gem?
