She is one of the most famous people in the world thanks to her starring roles in Grease and Xanadu.
Now nearly three decades on and still looking younger than her age, a smiling and radiant Olivia Newton-John graced the red carpet with her husband John Easterling by her side.
Olivia was in Melbourne celebrating and co-hosting her 3rd annual ONJ Gala which raises money, support and awareness for her Olivia Newton-John Cancer & Wellness Centre at the Austin Hospital Melbourne.
Olivia has been passionate and supportive of this cause having gone through her own battle with breast cancer in 1992. In the very same year she lost her father to liver cancer.
The ONJ Gala was held on Saturday at the Grand Hyatt Hotel in Melbourne with Deborah Hutton and entertainment reporter Richard Wilkins co-hosting the event.
Other attendees included The Voice 2013 winner Harrison Craig, The Veronicas, both who performed at the gala along with Olivia, as well as Bee Gee star Barry Gibb who was the special guest.
Olivia Newton-John will also take part in the Wellness Walk, leading the walk through the streets of Ivanhoe in Melbourne on Sunday 4th October.
