'Grease' Star Olivia Newton-John Kicks Off 2019 by Telling World She's Not Dead or Dying

Olivia Newton-John kicked off 2019 with a big announcement: She's not dead and she's not dying.

The 70-year-old "Grease" star and breast cancer survivor took to Twitter on Wednesday evening to clear up "greatly exaggerated" rumors about her health, in wake of publications citing a Radar Online report headlined, "Dying Olivia Newton-John Clinging On To Life To See Daughter Wed!"

Although Newton-John did announce in 2017 that she was diagnosed with cancer for a third time after doctors found a tumor in her lower back, she appeared to be in good health in the video message and said she's "doing great."

"Happy New Year, everyone. This is Olivia Newton-John, and I just want to say the rumors of my death have been greatly exaggerated," she said with a laugh in a Twitter video. "I'm doing great, and I wanted to wish all of you the happiest, healthiest 2019 that's possible. And thank you all for your wonderful love and support for me and my Olivia Newton-John Cancer Center in Melbourne, Australia."

Radar cited "a source" telling them, "Olivia's bodily functions appear to be shutting down, but she refuses to let go until she makes it through Chloe's wedding day!"

Before taking to Twitter to address the report herself, her representative told People it was "ridiculous" and "crap." Newton-John's niece, Tottie Goldsmith, also called B.S. on the report via an Instagram post earlier in the day on Wednesday.
