I respect my parents' opinion very much. No matter how old you are, what your parents think is very important. If they like your boyfriend or if they like some work you've done. And if they don't, it's more shattering than anybody else telling you, because they're the most honest.

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.

I love seeing young girls and their parents and grandparents at my concerts all loving the music from Grease when I perform those songs (and yes, I do perform a bunch of them!).

My cancer scare changed my life. I'm grateful for every new, healthy day I have. It has helped me prioritize my life.

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.

Fight each round take it on the chin. And never never never ever give in.
