Olivia Newton-John, best known for her role as Sandy in Grease, has passed away at the age of 73.
The sad news was announced on Newton-John's Instagram, via her husband John Easterling.
The caption reads, "Dame Olivia Newton-John (73) passed away peacefully at her Ranch in Southern California this morning, surrounded by family and friends. 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. In lieu of flowers, the family asks that any donations be made in her memory to the @onjfoundation."
Tributes immediately began pouring in from Newton-John's friends and collaborators.
Her Grease costar John Travolta wrote on Instagram, "My dearest Olivia, you made all of our lives so much better. Your impact was incredible. I love you so much. We will see you down the road and we will all be together again. Yours from the first moment I saw you and forever!
"Your Danny, your John!"
Fellow singer Mariah Carey told a lovely story on Twitter: "I dressed up as Bad Sandy for Halloween in 5th grade and thought I was everything. Years later, THE Olivia Newton-John walked out onto my stage in Melbourne, Australia and we sang our hearts out together to 'Hopelessly Devoted To You.' This is a moment I will never ever forget."
