Newly-slimmed down actor Rebel Wilson says Olivia Newton-John tried to help get her healthy "years before I took it seriously".
Wilson posted a lengthy tribute to the Grease and Xanadu actor who died on Monday (local time) at her California home from cancer.
Calling Newton-John a "true Aussie icon", Wilson said she was honoured to play her daughter in a 2011 movie.
"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.
"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.
"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," Wilson concluded her post.
In 2020, Wilson announced that she was embarking on a "year of health" with the aim of reaching a target weight of 11st 8lb (roughly 75kg) - a goal she achieved in November that year. According to reports, she has shed an impressive 70lbs (30kg).
Social media was swamped with tributes to the actress who played Sandy in 1978 movie Grease and had a pop career that included hit songs like 'Physical' and 'Xanadu'.
Grease co-star John Travolta led the tributes with an Instagram post saying he'd see his former co-star "down the road and we will all be together again".
