#7: Olivia Newton-John
Olivia Newton-John defined wholesome blonde stardom in the 1970s, dominating both pop charts and movie screens. Grease turned her into a global phenomenon, while hits like “Physical” and “Hopelessly Devoted to You” made her one of the decade’s most recognizable voices.

Later in life, Olivia focused on wellness, philanthropy, and cancer advocacy after her own long health battles. Her gentle public presence never faded, and when she died in 2022, tributes poured in from across generations who saw her as pure pop comfort and grace.
