Olivia Newton-John
Did you know that this Australian celebrity actually made it as a singer before she made the jump into acting? She was always talented at both, but it was some of her biggest hits that launched her to fame on the music charts before she even did the legendary musical, Grease.
Olivia Newton-John would be best known for her role as Sandy in Grease, where she played alongside a young John Travolta in a 1950s American high school. It would be a film that almost everyone on planet earth has seen at least once and the great songs will never be forgotten, nor will her.
