Actor John Travolta, who co-starred in the hit film musical "Grease" with Olivia Newton-John, has paid tribute to the late singer.
"You made all of our lives so much better, my beautiful Olivia," the actor wrote on Instagram. "Your influence was enormous. I adore you to pieces."
Newton-John and Travolta rose to international prominence in 1978 as bad boy Danny and lovely Sandy in the film musical "Grease."
Just a few years ago, the two reprised their roles for one special night in West Palm Beach, Florida, at the Coral Sky Amphitheatre for a sing-along of the film and a Q&A session.
Newton-John wore her distinctive yellow skirt and matching cardigan, as well as a white button-up shirt. Travolta sported a classic leather jacket and slicked back his hair.
It was the first time the two had dressed up since making the film more than 40 years ago, Newton-John remarked on Instagram at the time.
"We shall see you down the road, and we will all be together again," Travolta said in his tribute.
He signed it as follows: "Yours from the moment I saw you to the end of time! Danny and John are your names."
