John Travolta has shared a special tribute to Olivia Newton-John on what would have been her 74th birthday after she passed away last month following a long battle with breast cancer.
The Grease actor, 68, remembered his co-star by taking to Instagram to share a picture of himself and Olivia in the 1978 hit musical as their iconic characters Danny and Sandy.
Alongside the snap, he wrote: "Happy birthday my Olivia."
