We met her daughter earlier on in this list; now meet the matriarch of the Ecclestone family. Slavica has become a billionaire just off the back of having a pretty face, in a roundabout way. Born in Croatia, she was a highly desirable runway model who regularly worked for Armani. It was during one of these Armani fashion shows that she caught the eye of billionaire and Formula 1 Racing director Bernie Ecclestone. Despite him speaking no Croatian and her speaking no English, they married and had children. Those were the good times.
Unfortunately for Bernie, when the bad times arrived, they came at an almighty cost. Ecclestone filed for divorce after 23 years of marriage in 2008. The resulting settlement saw her awarded $1.2bn from her husband, making it the second most expensive divorce in all of human history. If only Kanye West had been around years ago to tell Bernie 'if you ain't no punk, holler we want pre-nup'.
