Olivia Newton John's daughter honors Grease legend on 74th birthday after making touching promise to beloved 'mama'
Olivia Newton-John's daughter Chloe Lattanzi has honored the Grease star on what would have been her 74th birthday with a touching post on social media. Tributes for the late Australian singer and actor flooded the Internet yesterday, after her nearest of kin shared a video of a special dinner hosted in memory of her beloved 'mama'. Dame Olivia Newton-John, best known for playing Sandy in Grease (1978), died last month at the age of 73, marking the end of her 'overwhelming' 30-year-long journey with breast cancer.
