“Grease” co-star John Travolta posted his condolences on Instagram.

“My dearest Olivia, you made all of our lives so much better,” Travolta wrote. “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!”

Newton-John’s Facebook page says she’s survived by her husband, John Easterling, daughter Chloe Lattanzi, two siblings and 15 nieces and nephews.
