I've always had a huge fear of dying or becoming ill. The thing I'm most afraid of, though, is being alone, which I think a lot of performers fear. It's why we seek the limelight - so we're not alone, were adored. Were loved, so people want to be around us. The fear of being alone drives my life.

Getting back into shape [after bringing twing] was challenging, like it is for anybody who has a baby. The first few pounds drop off really fast. And then you're like stuck with those last 10 to 20 pounds, let's say, and then you've really got to get disciplined.

I remember when I was 33 or 34, it was devastating because I realized I wasn't a kid anymore. The great thing about 40 was that I really felt like I had life experience and knew what I was doing now.

When I turned 40, I was like, huh. I accept myself more now. It was much more comforting.

If anyone can figure out how to balance my celebrity and my dual careers in music and film, it's me. I don't feel frightened; I feel challenged.

You can't take life for granted.

I always joke about letting the haters motivate you. Everybody has that in their life, people who doubt them or make them feel less than they are. It just takes faith and belief in yourself, and you've got to dig deep into that. That has to come from you - nobody's going to give you that.
