"Just giving you the heads up that Livvy is in good health, so let's leave that distressing rumor where it belongs", Newton-John's niece Tottie Goldsmith said on Instagram on January 2.
However, in a short statement overnight, Newtown-John's niece shut down the "distressing rumour", claiming her Aunt is in good health.
According to RadarOnline, Newton-John is only holding on to see her daughter, 32-year-old Chloe Lattanzi, marry her long-term partner James Driskill.
Newton-John said she has undergone radiation, adheres to a sugar-free diet and also take cannabis oil for pain relief and insomnia.
Good to hear, considering the star is battling cancer for the third time in 25 years.
The Grease star was diagnosed with breast cancer in 2017 and also has a tumour in the base of her spine. "Losing third fight with cancer; going home to die on her ranch", News.com.au reported.
"Olivia Newton-John's two upcoming speaking appearances in Australia were canceled due to scheduling conflicts with her upcoming promotional tour for her new book, Don't Stop Believin' and the ONJ Cancer Wellness & Research Centre's Wellness Walk & Research Run", read a statement posted on her social platforms.
"But having said that we have to face the fact of the matter that Olivia is very sick, she has stage four breast cancer".
In 2017, she made a decision to go public with her third battle and spoke of her mix of treatments - radiation as well as more natural remedies, as well as cannabis oil.
"I'm one of millions in this fight ..." So he [her husband] makes me tinctures. I see it as part of my mission.
Olivia Neton-John has shared a clip to reassure fans she is doing well.
"In California it's legal to grow a certain amount of plants for your own medicinal purposes", she said during an interview with Australia's Sunday Night program.
