Antoine Arnault
Some say Delphine's splashy new title may be setting the stage for a succession battle between her and her brother Antoine, also from Bernard's first marriage.
Not that he's ever gotten the short end of the stick. The 45-year-old, who has led the luxury brands Berluti and Loro Piana, got his own impressive promotion last month when his father placed him at the helm of the family's holding company, Christian Dior SE.
The dapper exec is also building a fashion family of his own. In 2020, he wed his longtime supermodel partner Natalia Vodianova, with whom he has two children. The dynasty continues!
