Olivia Newton-John’s Widower Says They Committed to 'Love Each Other Forever or Until the End of Time' (Exclusive)

John Easterling opens up about his undying love for his wife a year after her death

John Easterling has spent the past year finding light in the darkness.

With losing wife Olivia Newton-John to breast cancer and age 73 last August, "Things aren't easy," he says, "but you always have to just dig. Olivia was able to never lose sight of the good things. Love is everywhere."

An herbalist and naturopathic entrepreneur, Easterling, 71, traveled to his and Newton-John's "special place" in Peru this past June to hold a private ceremony with her ashes at the spot where they said “I do,” commemorating what would have been their 15th wedding anniversary.

The trip gave him perspective: “It lightened my heart and created a very strong focus forward. I had 15 years with this extraordinary human being. That experience itself is worth a lifetime.”

While grieving his wife, Easterling holds tight to the memories they made together. Before they met, he had never even seen the pop star's hit film Grease — though Newton-John would rectify that years later during a movie night on John Travolta’s private jet.

Back in the mid-2000s the two were both working with an environmental nonprofit when Newton-John invited Easterling — who was then living in Florida — to her show in Miami. “She walked out onstage singing ‘Grace and Gratitude,’ and people around me were crying,” he recalls. “It hit me straight in the heart: She’s a healer.”

The two, who both adored animals and the outdoors, soon fell deeply in love with one another. During their years together they made a promise. “The commitment Olivia and I had was that we would love each other forever or until the end of time, whichever came last,” says Easterling. “We’re still in that time frame."

At the home they shared in Santa Ynez, California, he keeps a memory table with his wife's favorite photos and mementos. "There's no replacing her," he says.

These days, he spends his time working with the Olivia Newton-John Foundation Fund to continue life-saving cancer research surrounding the efficacy of medicinal plants in her honor. Soon he'll join stepdaughter Chloe Lattanzi at Olivia's Walk for Wellness in Melbourne to help raise funds for the foundation and her Olivia Newton-John Cancer Wellness and Research Centre.

"Things have shifted, but we have her," he says. "We have the best of her to drive us forward."
