'Grease' star Olivia Newton-John dies at 73

Newton-John "passed away peacefully at her ranch in Southern California

livia Newton-John, who gained international fame as John Travolta's love interest in the hit movie "Grease," died on Monday at the age of 73 after a 30-year battle with cancer.

Newton-John "passed away peacefully at her ranch in Southern California this morning, surrounded by family and friends," said a statement from her husband John Easterling posted on her official social media accounts, Qazet.az reports.

The entertainer, whose career spanned more than five decades, devoted much of her time and celebrity to charities after first being diagnosed with breast cancer in 1992.

The British-born and Australian-raised star dedicated a number of albums and concerts to raise funds for research and early detection of the disease, including the construction of a health center named after her in her adopted home Melbourne.

"I don't like to say 'battled,'" a defiant Newton-John told Australia's Channel Seven TV in September 2018 after revealing she had been diagnosed with cancer for a third time.

"I like to say 'win over,' because 'battled' sets up this anger and inflammation that you don't want."
