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.

I love to design and remodel houses, from working with the contractors to picking the colours, materials, kitchen and bathroom accessories to finally what furniture goes where.

I keep a diary when I have time to. I always know that I'm either having a great time or I'm very busy when there are three weeks of nothing in my diary. But I like to look back because in ten years to the day I can know where I was and what I was doing, and that's a nice feeling.

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.

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.

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