I've always heard that she is/was in a longtime relationship with a wealthy and married Greek friend of her brother.
Indeed, I have heard the same. And that he was deceased.
Probably like Jackie O. and Maurice Tempelsman. If Irene's friend was unable to be divorced, they may have just decided to live their lives together, quietly.
was Maurice married when he hooked up with Jackie?
G
Yeah he was married.He and his wife separated in 1984. His relationship with Jackie started in 1980 and lasted until her death
