Olivia Newton-John's loved ones sense her presence in supernatural encounters one year after her death

Olivia Newton-John's daughter Chloe Lattanzi and husband John Easterling have experienced blue orbs, which they believe are signs from her spirit.
Lattanzi took a photo of her dog with a blue orb floating by, fulfilling a pact she had made with her late mother to appear after death.
Easterling captured a similar blue orb while traveling in Peru to scatter Newton-John's ashes.
Newton-John battled breast cancer for over 30 years and remained positive, using traditional and alternative treatments.
Lattanzi and Easterling continue Newton-John's advocacy by leading cancer research fundraisers in her memory.
