In a statement  posted to Instagram, her husband John Easterling wrote: “We ask that everyone please respect the family’s privacy during this very difficult time.

“Olivia has been a symbol of triumphs and hope for over 30 years sharing her journey with breast cancer.

“Her healing inspiration and pioneering experience with plant medicine continues with the Olivia Newton-John Foundation Fund, dedicated to researching plant medicine and cancer.”

Mr Easterling added that in lieu of flowers, donations be made to Dame Olivia’s foundation.
