The Daily Mail reported Saturday that Sassoon left none of his $150 million estate to his 41-year-old son, David, with whom he had an uneasy relationship.
"My son David Sassoon and his issue are hereby disinherited and shall take nothing under this will, and for the purposes of the will, shall be deemed to have predeceased me, leaving no surviving issue."
Sassoon, who adopted David in 1975, described him as a "mischievous" boy who once nearly peed on Johnny Carson's head during a fashion party. David spent time in reform school and developed a strained relationship with his father.
"There’s a certain point in my character where if I feel a situation is hopeless – walk away. Don’t torment yourself constantly. I walked away," Sassoon wrote in his autobiography.
He had two other surviving children, Elan and Eden, and a third child, Catya, who died of a drug overdose 11 years ago.
