John Easterling, husband of Olivia Newton-John, pays tribute to late actress with emotional Instagram post

John Easterling, the husband of Olivia Newton-John, paid tribute to the late actress in a touching Instagram post, describing their marriage and life together as a love that "transcends our understanding." Newton-John, best known for her starring role as Sandy in the musical "Grease," died Monday at the age of 73. 

Easterling on Wednesday wrote on Newton-John's Instagram account that his wife was a "healer" who used the "mediums of song, of words, of touch."

"She was the most courageous woman I've ever known," Easterling said. "Her bandwidth for genuinely caring for people, for nature and all creatures almost eclipses what is humanely possible. It is only the grace of God that has allowed me to share the depth and passion of her being for so long. In her most difficult times she always had the spirit, the humor, and the will power to move things into the light."
