John Travolta will always be hopelessly devoted to his late friend Olivia-Newton John. During the 95th Academy Awards, John took the stage to pay tribute to all the celebs we have lost this past year, including his beloved "Grease" co-star. "Through their immeasurable contributions, each of them left an individual and indelible mark that shared and informed us. They've touched our hearts, they've made us smile, and became dear friends, who we will always remain hopelessly devoted to," he said.
