Alex Von Furstenberg

Alex Von Furstenberg, 52, is the eldest child and only son of Diane von Furstenberg, who’s been a big deal in fashion since the 1970s and remains best known for her legendary wrap dress. His father, Egon von Furstenberg, was the scion of an aristocratic German family. But the bulk of the younger von Furstenberg’s wealth reportedly stems from his stepfather, septuagenarian American media/tech mogul Barry Diller, who has been married to Diane von Furstenberg since 2001 and has no biological children of his own. Diller, the former CEO of Paramount Pictures and current chairman of Expedia, boasts a healthy net worth of $4.9 billion.
