Nip/Tuck star Julian McMahon is mourning the death of his mother.
McMahon was by his mother Sonia’s hospital bedside in Sydney, Australia, when she lost her battle with cancer overnight. She was 77.
A statement said she passed away peacefully.
Lady Sonia McMahon was the former wife of Australia’s one-time prime minister Sir William McMahon.
She grabbed world headlines in 1971, wearing a revealing white dress to dinner with US president Richard Nixon at the White House.
The Washington Post described the dress as one of the most talked about items of clothing ever to be worn to the White House.
The Nip Tuck star, Lady Sonia’s only son, flew into Sydney from Los Angeles last week to farewell his mother.
