NEW YORK (AP) - Olivia Newton-John, the Grammy-winning superstar who reigned on pop, country, adult contemporary and dance charts with such hits as "Physical" and "You're the One That I Want" and won countless hearts as everyone's favorite Sandy in the blockbuster film version of "Grease," has died. She was 73.
Newton-John, a longtime resident of Australia whose sales topped 100 million albums, died Monday at her southern California ranch, John Easterling, her husband, wrote on Instagram and Facebook. "We ask that everyone please respect the family's privacy during this very difficult time," the message said.
From 1973-83, Newton-John was among the world's most popular entertainers. She had 14 top 10 singles just in the U.S., won four Grammys, starred with John Travolta in "Grease" and with Gene Kelly in "Xanadu."
