John Travolta paid tribute to lifelong friend and former co-star Olivia Newton-John, who died Monday at the age of 73.
“My dear Olivia, you have made our whole life so much better. Your impact was incredible. I love you so much,” he wrote in a touching Instagram post, accompanied by a throwback photo of Newton-John.
‘We’ll see you on the road and we’ll all be together again. Yours from the first moment I saw you and forever! Your Danny, your John!
The actors famously played side by side in “Grease.”
Travolta, 68, played Danny Zuko in the iconic 1978 film, while Newton-John played Sandy Olsson. The pair remained close for decades after collaborating on the much-loved movie musical.
Newton-John died on her Southern California ranch surrounded by family and friends after a long battle with cancer, according to a statement on her official Facebook page.
“A symbol of triumph and hope for more than 30 years, Olivia shares her journey with breast cancer,” the statement read.
“Her healing inspiration and pioneering experience in plant medicine continues with the Olivia Newton-John Foundation Fund, which is dedicated to researching plant medicine and cancer.”
Travolta has been in regular contact with Newton-John over the years. He opened up about their relationship — and shared a hopeful health update — during a 2019 interview with Us Weekly.
“We were together not long ago, about three months ago, and we text each other all the time,” he told the outlet at the premiere of his movie “The Fanatic.”
“When I go to see her in person, we usually have dinner and catch up. And lately we’ve been talking about trying something together.”
He added that the Australian actress “did a great job” and “[looked] fantastic!”
“I’m so proud of her,” Travolta gushed on. “She acts like i’ve never seen anyone [do].”
Just a year earlier, Newton-John revealed that she had been diagnosed with breast cancer for the third time.
“It was a challenging year because I broke my sacrum and I had to relearn to walk and all that,” Olivia, whose stage four cancer had spread to her bones, told Entertainment Tonight at the time.
“But I’m strong and I’m back, and I feel good and loving every minute.”
Newton-John is survived by her husband of 14 years, John Easterling, and her daughter, Chloe Lattanzi, 36.
