John Travolta shared a special tribute to Olivia Newton-John on his Instagram story earlier Monday on what would have been her 74th birthday.
The Grease actor, 68, remembered his former co-star and close friend by wishing her a happy birthday.
The actress suddenly passed away earlier last month on August 8, after her breast cancer returned in 2017 as stage four. Her death caused a wave of tributes to pour out as individuals around the world mourned her death.

The Saturday Night Fever star uploaded a photo of both Olivia and himself from their iconic roles as Danny and Sandy from the 1978 musical film, Grease.
He typed out, ‘Happy birthday my Olivia,’ in a caption underneath the photo that he shared onto his Instagram story.
The two stars first met on the set of Grease in 1978, and retained a strong friendship for 44 years until her passing.
In a past interview with People, Olivia talked to the publication about the hit film and the bond that John and herself made following its success.
‘At the premiere you got the feeling from the energy that something was happening. It was a huge response. I feel grateful to be a part of that and to have worked with him. We’ve stayed friends ever since.’
Shortly after Olivia’s sudden death, John had posted a tribute onto his main Instagram page as he mourned her passing.
