John Travolta says he is "very proud" of his "Grease" co-star Olivia Newton-John as she battles cancer for a third time.
The 70-year-old actress is currently battling breast cancer for the third time, and her "Grease" co-star John, 65, has gushed about her strength as she deals with stage four cancer.
He told Entertainment Tonight: "She looks incredible. She doesn't look any different than [she did] years ago, and I'm very proud of her. I'm very happy about Olivia."
Olivia previously insisted she feels "lucky", despite being diagnosed with stage four cancer.
She said: "I'm so lucky that I've been through this three times and I'm still here. We know we're gonna die at some point, and we don't know when it is. When you're given a cancer diagnosis or a scary honest diagnosis, you're suddenly given a possibility of a time limit. So every day is a gift.
