Olivia Newton-John has recruited fellow cancer survivor Sharon Osbourne to join her on a 21-day trek of the Great Wall of China.
The 'Grease' star - who has battled breast cancer - hopes the walk will raise vital funds for the Wellness Centre at the Austin Hospital in Melbourne, Australia.
Osbourne will also take part in the trek on April 7 with Leeza Gibbons, Joan Rivers and former Party of Five star Scott Wolf.
Newton-John says: "The walk on the Great Wall symbolizes the cancer journey. It's long and arduous, but we'll triumph in the end.
"I want to do it for my hospital, but now it's a challenge for me personally to do this."
