Sibil de Selis Longšamp

Sibil de Selis Longšamp is recognized as the former partner of Albert II of Belgium and the mother of Delfine Boel. Their relationship, which began in the 1960s, was marked by secrecy and societal challenges due to the royal's marriage and the conservative views of that time. Sibil's decision to keep Delfine's paternity hidden was rooted in a desire to protect both her daughter and Albert's royal status.
