Olivia Newton-John has passed at 73 from cancer. Upon her passing she immediately made headlines around the world.

Her Grease co-star John Travolta said she “made all of our lives so much better” while its director said: “What you see is what you get with her.”

The British-born Australian singer and actress was known for playing Sandy in Grease, one of the most successful film musicals ever made. She died peacefully at her California ranch surrounded by family and friends.

An actress and musician, Newton-John achieved commercial success as a country singer and sold millions of records globally.

Grease was the biggest box-office hit of 1978, and gave Newton-John three huge hit singles, including You’re The One That I Want and Summer Nights, both performed with co-star John Travolta.
