So sad to hear this news. Olivia Newton-John passed away peacefully this morning at her ranch in Southern California surrounded by family and friends. She was 73 years old. “Olivia has been a symbol of triumphs and hope for over 30 years sharing her journey with breast cancer,” her husband John Easterling wrote. In addition to her incredible singing and acting career, Olivia Newton-John spent the majority of the latter half of her career as an advocate for cancer patients and survivors.
