Amid Health Rumors, Newton-John Quotes Mark Twain

Olivia Newton-John revealed her third cancer diagnosis last year with optimism: "I believe I will win over it," she said. The Grease actress remains of the same mindset despite reports suggesting she has only weeks to live, per People. "I just want to say the rumors of my death have been greatly exaggerated, to quote a very famous quote, and I'm doing great and I want to wish all of you the happiest, healthiest 2019 that's possible," the smiling 70-year-old said in a video shared Wednesday. Her niece, Tottie Goldsmith, is also trying to calm worried fans. "You can rest assured she is going nowhere and in really good health," she says, per News.com.au. (More Olivia Newton-John stories.)
