I never know if a song's going to be popular so I don't select them with that in mind. All I can do is follow my heart and my gut and go for songs that make me feel great.
I would be a horrible lip-syncher. I would only ever sing live - that's why people come and see the show. It's not the easiest thing in the world to sing and dance at the same time, which is why I'm grateful to be able to do both.
I'm going to take care of the man I'm with. I grew up in a household where my mum takes care of my dad - she cooks, she does everything - and that's the kind of girl I am.
I've always been too hard on myself to behave like I've arrived or even to enjoy whatever success I've had. I've always envisioned myself higher than where I was and I still do. With each success I think, 'That's nice but I'm supposed to go there!'
When I'm a mum, I'm not going to be one of those mums who has nannies. Actually, I might have nannies - never say never - but I'm not having someone else raise my kids.
Although religion was around me my whole life I never felt it was forced upon me. It is my centring, my grounding, the soul of me. I feel I'm nothing without it.
The problem is I'm a perfectionist, so the producer might say he's happy with my vocal take but I'll say, 'No, it can be better.' I'll do it again and again until I feel I've got the truth out of a song.
When I hit my thirties, that's when I calmed down and I wasn't so tough on myself. I wasn't doing the yo-yo dieting any more. I gave myself a break. I think that, if you're more accepting of yourself, you're more free and open and can just allow more people in.
I was a shy kid, but somehow I knew I would make it as a performer. I'd always be telling my mum that I was going to be a famous singer. In my school yearbooks I would write, 'Remember me when I'm famous.' I knew I had a gift.
I come from a strong religious background, and I had a very conservative upbringing. So I was nervous, and confused. Here I was wanting to be Whitney Houston, so why did I have to dress in lingerie to do that? I didn't get it.
Growing up, my mom was very strict about how I dressed and how I behaved, and I said to myself that I wasn't going to be like that. But now I know I'm going to be exactly like my mom. I'm going to be worse!
Growing up, I was very conservative in my wardrobe, so when I first joined the Pussycat Dolls, the biggest challenge was wearing those cabaret costumes. I didn't feel comfortable showing my body so much, showing my legs and butt, chest and midriff.
