I love animals. They give so much to you and demand so little. And you can trust them.

John [Travolta] and I have remained very close friends ever since we did Grease. When I was told that "You're the One That I Want" was named the #1 duet in history and, during a text chat with John letting him know he said "we should record a Christmas song." Of course I said yes.

I really love performing with an orchestra and am very excited to do so with the Kalamazoo Symphony.

I feel so fortunate and grateful to be a survivor of breast cancer. I see it as a gift.

When you have a cavity in your tooth and you let it get worse, eventually you have to get a root canal. If you have something that isn't right, the earlier you treat it the easier the treatment is going to be. That's kind of common sense.

I just wanna do my music.

Singing at the Opening Ceremonies of the Sydney Olympics in 2000 was amazing and, probably the highlight of this decade is the opening of the Olivia Newton-John Cancer and Wellness Centre in my hometown of Melbourne, Australia.
