The world is mourning the loss of Olivia Newton-John on Monday afternoon.
The longtime singer, songwriter, actress and activist died at the age of 73 on Monday.
Newton-John, perhaps best known for her role in "Grease," died following a decade-long battle with breast cancer.
Tributes are pouring in from fans across the world, including several from the sports world.
"Among my greatest wishes was that, someday, I would meet Olivia Newton-John, and tell her that I saw Grease six times in the Summer of '78 because of her, and that I was always happier after hearing her sing anything. She was a lifetime favorite. This is hard to take. RIP," David Aldridge wrote.
"Rest In Peace, Olivia Newton-John," Rex Chapman wrote.
"OLIVIA NEWTON JOHN I LOVE YOU WITH ALL MY HEART BUBBA FOREVER," wrestler The Iron Sheik wrote.
Our thoughts are with Olivia's friends and family during this difficult time.
May she rest in peace.
