#9: Allegra Versace – $800 Million
She is the daughter of famous fashion designer Donatella Versace and ex-model Paul Beck. It must be nice to be multi-millionaire at the age of 28. She divides her time between the houses in Milan, New York City and Los Angelas. The funny fact here is that the money is not from her mom, but actually from her uncle Gianni Versace who left her a 50% stake in his company.
