'Good Morning America' exploited Joan Lunden's pregnancy, but you won't see me bringing my babies on the air. The only reason I'm talking about the babies at all is that they've been with me on the show since I became pregnant. After a while, I had to acknowledge this pumpkin tummy.

My guess is that people look at me and project their own values - importance of family, ego is healthy but not the biggest thing. I don't know. I can't explain my popularity.

When I was diagnosed with bipolar disorder the year I turned 50, it was certainly a shock. But as a journalist, knowing a little bit about a lot of things, I didn't suffer the misconception that depression was all in my head or a mark of poor character. I knew it was a disease, and, like all diseases, was treatable.

Twins are a high-risk pregnancy, by definition. The quieter I am, the longer I can keep them growing.

I have been fiercely private, in part because I could never understand how a journalist could be otherwise. I was also the mother of small children, and security concerns were paramount.

You cannot look at a sleeping cat and feel tense.

I was an unusually private person - in a way, kind of insufferably so. I think I thought the celebrity thing when it happened was a temporary phenomenon, and I was above it.
