The "Great Walk to Beijing" was a fundraiser for my cancer center. It was a three-week trek with fellow cancer "thrivers," including celebrities ranging from Joan Rivers to Leeza Gibbons, and Olympians.

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.

Acting is a difficult profession, it really is. It's different than singing. With singing you may have one song and four people to record it - but they'll all do it differently and they'll all have that option. Whereas with actors there might be one part, and five hundred actors all want the same role - it's so much more competitive. It's an incredibly painful profession because you get so much rejection.

I'm happy, and I think being happy keeps you looking young.

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.

There's a rumor going around that I'm Miss Goody-two-shoes from Australia. Well, that's a laugh. I'm really Miss Goody-two-shoes from England!

Cancer got me over unimportant fears, like getting old.
