Olivia Newton-John’s Grease co-star John Travolta has wished her a beautiful tribute for what would have been her 74th birthday.

The actress would have celebrated her 74th birthday on September 26 but unfortunately lost her battle to breast cancer on August 8.

John Travolta wished Olivia a loving tribute on his Instagram story with a photo of the pair in the classic 1978 musical movie.

The photo showed the pair as lovebirds Danny Zuko and Sandy Olsson with the caption, “Happy birthday my Olivia”.

Olivia’s daughter Chloe Lattanzi also marked the special day with an intimate dinner with close family and friends.

She shared a video of the event with everyone wishing Olivia a “happy birthday mama”.

The post comes a few hours after Olivia’s husband John Easterling shared an adorable story of their married life with a never-before-heard story of how the couple got caught in a dangerous storm while on a boating trip.

John Easterling was the one to announce the news of Olivia’s passing on her Instagram, in which he included an appeal to continue her good works in the field of cancer research:

“Dame Olivia Newton-John (73) passed away peacefully at her Ranch in Southern California this morning, surrounded by family and friends. We ask that everyone please respect the family’s privacy during this very difficult time,” he wrote.

“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. In lieu of flowers, the family asks that any donations be made in her memory to the @onjfoundation.”

Her daughter Chloe also shared a series of heartwarming photos upon the news breaking as celebrities and fans alike offered their condolences.
