Oona Sperr Sues Billionaire Ex for $400M | Philadelphia News

A billionaire oil tycoon’s shocking betrayal is sparking a $400 million lawsuit from his ex-girlfriend, Oona Sperr — the daughter of a famed Philadelphia architect. Once promised lifelong financial security and property ownership during their four-year relationship, Sperr now claims Sid Bass, 84, abruptly ended things after secretly forming a coercive bond with another woman, Althea Viafora Kress. After leaving her interior design career to care for Bass and their homes, Sperr says he reneged on all promises, offering only meager annual payments — no property, no support for her mother. With Bass’s fortune estimated at $4.4 billion and a history of costly divorces, this New York suit could redefine how wealth and power play out in personal relationships.
