Olivia Newton-John is reported to have only weeks to live after being diagnosed with cancer for a third time.
According to radaronline.com, people close to the Grease star say her health has rapidly deteriorated and her prognosis is now "weeks, not months."
However, the publication also claim the 70-year-old is determined to survive long enough to see her only child Chloe Lattanzi marry her partner James Driskill in early 2019.
"Olivia's bodily functions appear to be shutting down, but she refuses to let go until she makes it through Chloe's wedding day," a source told the website.

The Hopelessly Devoted to You singer was diagnosed with breast cancer in June 2017. She also has a tumour in the base of her spine.
Newton-John is currently living on a ranch in California with her husband John Easterling, where she is reportedly planning to spend her final days.
"I refuse to die in a hospital room. I’ll go on my own terms, in our home and in my own bed — but not until Chloe says, ‘I do,'" Olivia reportedly told a friend.
In September last year, the star told Sunday Night she had decided to treat this cancer with "modern" medicines and natural remedies.
"I’m treating it naturally and doing really well," she said at the time.
Newton-John was previously diagnosed with breast cancer 25 years ago in 1992, after finding a lump on her right breast.
The Psychical hitmaker - who has Chloe with her ex-husband Matt Lattanzi - underwent a partial mastectomy and six months of treatment, before getting the all clear.
However, there was more heartache for the star when she was diagnosed with cancer in her shoulder in 2013, after she was involved in a minor car accident.
Newton-John previously said fighting cancer "taught her compassion".
She said: "I am grateful for the experience because without it I would not have done many of the things I have done in my life. It's taught me compassion for those going through difficult times."
