Olivia Newton-John, the British-Australian pop singer who dominated the pop charts of the 1970s and ’80s with mega hits “Hopelessly Devoted to You,” “Magic,” and “Physical”—and jolted audiences with her naif-to-naughty turn as Sandy in one of the top-grossing movie musicals of all time, Grease—died Monday at her ranch in Southern California, according to a message on her official Facebook page. Newton-John was fighting stage 4 metastatic breast cancer—she’d endured breast cancer on and off since 1992, but it had returned in 2017. She was 73.
