Danny is grieving the loss of his Sandy.
Olivia Newton-John passed away on Aug. 8 at the age of 73, her husband John Easterling announced on Instagram. As family, friends and fans mourn Olivia, her Grease co-star John Travolta—who played Danny Zuko in the film—penned a heartbreaking tribute to his late friend.
"My dearest Olivia, you made all of our lives so much better," he wrote on Instagram alongside a picture of Olivia, who played Sandy Olsson in the 1978 classic. "Your impact was incredible. I love you so much. We will see you down the road and we will all be together again. Yours from the first moment I saw you and forever!"
John signed off the heartfelt message with, "Your Danny, your John!"
Since starring in the film decades ago, the two have reunited frequently to celebrate the legacy of Grease.
"Meeting Olivia, beyond a shadow of a doubt," he raved. A sentiment Olivia echoed: "I have to say the same because John talked me into doing it and that was a magical day."
While the two are perhaps best known for Grease, Olivia and John also teamed up again on other projects.
In 1983, they worked together on the movie Two of a Kind, and in 1987, they appeared in Michael Jackson's music video "Liberian Girl."
Indeed, they've always gone together…
