Oh to be young, in love and ridiculously rich! Petra Ecclestone, who may not be as notorious as Paris Hilton, is just as much of an heiress. She is set to buy for herself and her fiancé a mansion that used to belong to the late Hollywood producer Aaron Spelling. The estate once fetched a cool $150 million, but is now in escrow for $85 million to Ecclestone. Either amount would be mere chicken feed to the blonde heiress whose father, Formula 1 CEO and president Bernie Ecclestone, is worth $4 billion. The racing heiress already owns a mansion in London. The lucky guy she is engaged to is London businessman James Stunt.
