KEY POINTS:
Paris Hilton may be US$60 million ($78 million) out of pocket, according to news reports.
Her billionaire grandfather is reportedly so appalled by her behaviour - including her jail stint for drink-driving - that he has decided to cut her inheritance.
Family patriarch Barron Hilton has been embarrassed by her behaviour before. He was reportedly upset when her home sex video was leaked to the internet. But the Sydney Daily Telegraph reported that the 79-year-old considered her 23-day jail sentence the last straw.
Barron Hilton has decided the money from his inheritance will go to a charity instead.
He is the only family member in the Hilton clan left with a large stake in the Hilton hotel chain. He is due to receive about $2.4 billion from an impending sale of the company to a private equity firm.
The Telegraph quoted author, Jerry Openheimer, who wrote a bigraphy of the Hiltons, House of Hilton, as saying he did not want to leave unearned money to the family.
"He was, and is, extremely embarrassed by how the Hilton name has been sullied by Paris."
