My wish is that all all women age 20 and above perform monthly breast self-examinations.

I do have high standards, but I don't expect anything from anyone that I don't expect from myself.

My biggest mistake was my best lesson... you don't learn anything when everything is going perfectly.

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.

A few years ago I appeared on GLEE and, Jane Lynch and I did a remake of the song that was very popular - someone told me it was in the Top 100 when it was released. First, walking on the set of GLEE the day we filmed it was surreal as they had recreated the entire original set from the music video. It was bizarre - but fun.

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.

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.
