Olivia Newton-John's family speak out following reports she ‘has weeks left to live’

Yesterday Olivia Newton-John fans were left devastated after it was reported she only had weeks left to live after being diagnosed with cancer for a third time.

According to radaronline.com, people close to the Grease star said her health had rapidly deteriorated and her prognosis was now "weeks, not months."

However, the 70-year-old's niece, Tottie Goldsmith, has spoken out on behalf of the You're The One That I Want singer in an attempt to shut down "sick rumours" she was dying.

Goldsmith told the Seven Network she had been allowed to speak publicly about her famous aunt.

"You can rest assured she is going nowhere and in really good health. A sick rumour," she said.

She later posted a photo of herself and Newton John smiling on Instagram with the caption: "Just giving you the heads up that Livvy is in good health, so let's leave that distressing rumour where it belongs."

The iconic Aussie star's American representative Michael Caprio reportedly laughed when contacted by news.com.au, saying reports of his client's imminent demise were "hilarious".

"No she has not," Caprio said. "You might want to get better sources versus reading tabloids."

While her social media manager Randy Slovacek told The Herald Sun newspaper: "We have stated over and over again publicly she's feeling better. People just seem to want to believe some dramatic turn."

The Hopelessly Devoted to You singer was diagnosed with breast cancer in June 2017. She also has a tumour in the base of her spine.

In September last year, the star told Sunday Night she had decided to treat this cancer with "modern" medicines and natural remedies.

"I’m treating it naturally and doing really well," she said at the time.

Newton-John was previously diagnosed with breast cancer 25 years ago in 1992, after finding a lump on her right breast.

The Psychical hitmaker - who has Chloe with her ex-husband Matt Lattanzi - underwent a partial mastectomy and six months of treatment, before getting the all clear.

However, there was more heartache for the star when she was diagnosed with cancer in her shoulder in 2013, after she was involved in a minor car accident.

Newton-John previously said fighting cancer "taught her compassion".

She said: "I am grateful for the experience because without it I would not have done many of the things I have done in my life. It's taught me compassion for those going through difficult times."
