My age doesn't seem like a reality to me. I still feel like I am 12 years old. But I've had an interesting journey.
My mother wasn't one for boundaries, but when you're given freedom you crave structure. That's probably why I never did anything too outrageous as a kid.
My parents were opposites. My mother was the free spirit and my rather a strict disciplinarian. They split up when I was three and despite the issues that came with that, I know we were all better off that way. They were not meant to stay together.
When you don't look like your parents. you inevitably have questions about your identity. My mother is white Irish American, my father was African American with a bit of Venezuelan. I remember drawing my family in kindergarten and colouring my face tan and my mum's pink, which was fine, but when I coloured my father's face brown, the teacher told me I had used the wrong crayon. It took me over 20 years to deal with being bi-racial.
Ambition is a talent in its own right. I had the gift of music, but it was ambition that enabled me to translate that into my career.
I thought being famous would validate me, but also knew I didn't want to be poor. We had 13 homes when I was growing up, and never owned one of them. I always felt that the rug could be pulled from under us and I was determined I wasn't going to live like that.
People call me a diva — but that is just so they can put me in a box. My mother was an opera singer, so I think I understand the word “diva” enough to know that I'm not one.
The one thing I forgot for too long was the importance of having fun. I was hanging out with Joss Stone recently and realised that when was her age, I never mingled with other artists. I do wish that I had been able to enjoy all that more back then.
I never believed in marriage, because I always thought people get divorced anyway. I had no template for a proper relationship, which goes a long way to explaining why I made a bad choice for the wrong reasons. [Her ex-husband is Tommy Mottola, the former head of Sony and the man credited with mentoring her to stardom; they divorced in 1998.]
When you obsess about something, and someone comes along who is prepared to obsess with you — that is a heady mix. Tommy and I bonded over music and his belief in me, which was great. But he became too controlling. I called our home Sing Sing, because it was like a beautiful prison. I had no freedom or downtime.
There are women who are manipulated all their lives, but I'm not one of them. I have an in-built radar now that prevents anyone too controlling coming too close.
My “breakdown” was my breakthrough. After my marriage ended, I worked myself into the ground. Eventually my body reminded me that I was human [she was hospitalised after collapsing in 2001] and I needed to create balance in my life.
Casual sex destroys self-respect. Some people use it to feel better about themselves but in fact it ruins lives. I've seen it for myself [her elder sister, Alison, is a former prostitute and drug addict] and that is why have never been comfortable with promiscuity.
Once you become famous, you are not normal. Everyone has an agenda, and for a long time I didn't know who could trust. But you can't live like that forever — you have to be able to dive in and take the risk that you might get hurt.
I would not want a child to be trapped by my fame. I've chosen this life, but my child would be born into it. I'm not saying never, but I'd have to be in a place where it felt right.
I'm no longer afraid to be who I am. I feel I can get through anything, especially after the last few difficult years. I'm here, and I am grateful beyond belief for that.
