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 an 18-years thriver, I call myself, not a survivor, because I feel like I'm in thriving my life even better than I ever have, and I want to encourage other women that are going through this journey that here I am.

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 simply have a marvellous life, a very lucky life.

As for highlights, of course "Grease" changed my life and I will always be grateful for that experience.

I live every day to its fullest extent and I don't sweat the small stuff.

I had a good, sound upbringing with sensible people around me. I was brought up by intelligent parents. My mother always said to me, "You've got to work at your career and you've got to be good at it. Okay, you've had a bit of success but that's not longevity. You've got to really work for a long time."
