Olivia Newton-John's niece clarified that her aunt is in "good health"
"You can rest assured she is going nowhere and in really good health. A sick rumour" Fox News quoted Olivia's niece Tottie Goldsmith as saying.
Last week, it was reported that Olivia's "bodily functions [appeared] to be shutting down" but that she was "clinging to life" to see her daughter, Chloe Lattanza, get married.
In September, the 70-year-old star revealed that her cancer had returned in the form of a tumour at the base of her spine and that she was using medical cannabis as a treatment for the illness.
Olivia was first diagnosed with breast cancer in 1992 and beat the disease. In 2013, she was diagnosed with a tumour in her shoulder.
