Olivia Newton-John rumours: Niece Tottie Goldsmith shuts down talk her auntie is dying

Olivia Newton-John's niece and management team have laughed off reports the Grease star has only weeks to live.

The 70-year-old was diagnosed with breast cancer in 2017, with another tumour in her spine. According to media site RadarOnline, she's rapidly become sicker and her bodily functions are shutting down.

She reportedly wants to make it to her daughter Chloe's wedding.

"You can rest assured she is going nowhere and in really good health - a sick rumour," her niece Tottie Goldsmith told news.com.au, seeking to shut down the rumours.

She posted a photo on Instagram with her mother, saying "Livvy is in good health, so let's leave that distressing rumour where it belongs".

"You might want to get better sources versus reading tabloids," her manager Michael Caprio said when contacted by news.com.au.

The 'Xanadu' singer's social media manager backed that up, telling the site: "We have stated over and over again publicly she's feeling better. People just seem to want to believe some dramatic turn."

The original source of the story appears to be US tabloid the National Enquirer, which first revealed the Bill Clinton-Monica Lewinsky affair, but has a history of running false stories and paying sources for information, which is frowned upon by most media outlets.
