One of the more recent celebrities to react to Newton-John's death is Kate Hudson, who also covered "Hopelessly Devoted to You" on Instagram, singing to her daughter, Rani, and writing about how Newton-John inspired her growing up. "There are a handful of people in my life who inspired me to lock myself in my bedroom and sing from the top of my lungs in the mirror. Mimicking every move she made, wishing I could hit those clean high notes and striving to try with my little rasp," she said in her caption.

"What a lovely light of a human. She was an inspiration to me as I dreamed of what my performers life ahead may be. Thank you for sharing your light to the world as it moved and shaped little girls like me. May we all today sing for Olivia and celebrate her courageous years of fighting," she continued.
