The iconic singer and Grease star died peacefully at the age of 73 at her home in Southern California on Monday (August 8).
Wilson, who played Newton-John’s daughter in the film A Few Best Men, has now become one of the latest stars to pay her respects, honouring the late star with a heartfelt Instagram post.
“@therealonj, you were the most gorgeous lady inside and out, you are a true Aussie icon and to play your daughter on screen in A FEW BEST MEN was beyond an honour,” Wilson wrote alongside an image of herself smiling with Newton-John and co-star Laura Brent.
The Senior Year star also noted how Newton-John’s role as Sandy in the 1978 musical Grease had inspired her as a kid growing up in Australia.
“Seeing you star in the huge Hollywood blockbuster GREASE with your natural accent was so instrumental to me as a little girl, helping me to believe that it was possible for an Aussie girl to star in huge international musicals,” she wrote.
“You were the reason I auditioned for my high school production of GREASE at 15 – I was only in the chorus, but it was a start! You tried to teach me about health years before I took it seriously. You were so kind to me and it was such a blessing to know you Olivia.
“I’ll never forget us singing at the piano in our lunch break on set together – what a complete legend you are! I am so sad you are gone. Love and Light always to you ONJ, Rebel xoxo.”
News of Newton-John’s death was announced by her husband, John Easterling, on Tuesday (August 9). He wrote in a statement: “Olivia has been a symbol of triumphs and hope for over 30 years sharing her journey with breast cancer.
“Her healing inspiration and pioneering experience with plant medicine continues with the Olivia Newton-John Foundation Fund, dedicated to researching plant medicine and cancer.”
John Travolta, who starred opposite Newton-John in Grease as Danny Zuko, was one of the many stars to pay tribute to the singer-actress, writing in a social media post: “My dearest Olivia, you made all of our lives so much better. Your impact was incredible. I love you so much.
“We will see you down the road and we will all be together again. Yours from the first moment I saw you and forever! Your Danny, your John!”
