Singer and actress Olivia Newton-John dead at 73

The British-born Australian actress and singer died on Monday, her family confirmed in a post on Instagram. The Grease star was diagnosed with breast cancer in 1992, and underwent successful treatment before the cancer returned in 2017.

Olivia Newton-John, the Grammy-winning superstar who reigned on pop, country, adult contemporary and dance charts with such hits as Physical and You're the One That I Want and won countless hearts as Sandy in the blockbuster film version of Grease, has died. She was 73.

Newton-John, a longtime resident of Australia whose sales topped 100 million albums, died Monday, her husband John Easterling wrote on Instagram and Facebook.

"Dame Olivia Newton-John, (73) passed away peacefully at her ranch in Southern California this morning, surrounded by family and friends," Easterling, announced in the post.

Newton-John's family did not give any details about the cause of her death but described her as "a symbol of triumphs and hope for over 30 years sharing her journey with breast cancer."

Newton-John was diagnosed with cancer in 1992, and underwent successful treatment before the cancer returned in 2017.

From Melbourne to Grease

Newton-John was born in Cambridge, England, in 1948, the daughter of German literature professor Brin Newton-John and Irene Born, whose father was Nobel Prize-winning physicist Max Born.

The Newton-Johns moved to Melbourne, Australia, when their daughter was 5, but she returned to England in her teens and lived with her mother after her parents broke up.

Newton-John had early dreams of becoming a veterinarian but was winning singing contests in high school and before age 20 had toured army bases and clubs, and recorded her first single, Till You Say You'll Be Mine

From 1973-83, Newton-John was among the world's most popular entertainers. She had 14 Top 10 singles just in the U.S., won four Grammys, and starred with John Travolta in Grease and with Gene Kelly in Xanadu

Both musically and image-wise, she reinvented herself. The blonde, ever-smiling Newton-John initially favoured mild pop-country songs such as Please Mr. Please and Have You Never Been Mellow and soft-breathing ballads like I Honestly Love You, which in 1975 won Grammys for best female pop vocal and record of the year.

But she picked up the tempo in Grease, especially after Sandy ditched her white sweaters and blouses for waist-high, black leather pants. 

The fast-stepping Travolta-Newton-John duet, You're the One That I Want, was one of the era's biggest songs and has sold more than 15 million copies.

"My dearest Olivia, you made all of our lives so much better," Travolta wrote in an online post.

"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 moment I saw you and forever! Your Danny, your John!"

Physical, her bouncy, R-rated smash released in 1981, was No. 1 for 10 weeks and was named Billboard's song of the year despite being banned by some radio stations. An aerobics-friendly promotional clip, filmed in the early years of MTV, won a Grammy for best video.

Cancer journey

Newton-John had a few later hits, but her career declined and she became more likely to make news because of her private life.

In 1992, as she was preparing a concert tour, her father died and she was diagnosed with breast cancer.

Her marriage to actor Matt Lattanzi, with whom she had a daughter, actor-singer Chloe Lattanzi, broke up in 1995 and a years-long relationship with cameraman Patrick McDermott ended mysteriously.

McDermott went missing during a 2005 fishing trip in California and his fate remained unknown years later. Numerous reports alleged that he was living in Mexico, with a new girlfriend.

"He was lost at sea, and nobody really knows what happened," Newton-John told Australia's 60 Minutes in 2016. "It's human to wonder. But you know, those are the things in life you have to accept and let go. Because whenever you go through difficult times, there's always those concerns."
