(LOS ANGELES, CA)- Four time Grammy Award winning singer and actress Olivia Newton-John has died following a decades-long battle with breast cancer.

She was 73.

Her recording career began in England at the age of 18 with the release of the “Till You Say You’ll Be Mine” for Decca Records in 1966.

She scored her first number one hit stateside in 1971 with the release of “If Not For You” which was written by Bob Dylan, and later won a Grammy in 1973 for the song “Let Me Be There” which went gold.

Newton-John’s biggest success came in 1978 when she played Sandy Olsson opposite John Travolta in movie ‘Grease’ whose soundtrack spawned 4 hit singles including ‘You’re the One That I Want’ and ‘Summer Nights.’

Later, she scored a number one hit with the song ‘Physical’, which held the top spot for 10 weeks in 1981.

Her battle with breast cancer began in 1992, but following a long remission it reappeared in 2017.

Following her cancer diagnosis, she became an outspoken advocate and research and treatment.

Her husband, businessman John Easterling says she died at her ranch in Southern California surrounded by friends and family.

Born in Cambridge, U.K. on Sept. 29, 1948, Olivia Newton-John was raised in Melbourne, Australia, the youngest of three children.

In addition to her husband, she leaves behind a daughter, singer and actress Chloe Lattanzi.
