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.

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!

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.

I definitely have the eye of the tiger. I've fought my way to where I am and will continue to do so. I'm a hard worker - I get it from my family. We only know work. Nothing was handed to us. When I believe in something, I go after it. It's very hard to tell me 'no.'

I don't like my thighs, the back of my legs or my chubby knees. I wear clothes that show off my legs in pictures and videos but not often when I'm appearing live.

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 think the sexiest thing about a man is that he's confident. Sure, sometimes you meet someone and you see his appearance first, but then you get to know him, and he looks completely different to you.

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 was a very quiet, shy child. I grew up in a small town, Louisville, Kentucky, and there weren't too many Hawaiian-Filipino girls, so I stuck out like a sore thumb. I didn't look like everyone else and didn't feel I belonged... But these things only build character and make you stronger. It taught me to grow into the woman I was to become.

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'm no diva but I can be annoying in a recording studio. Of course I try to be a diva in terms of confidence of performance and owning a song but I've never behaved like one in terms of the negative connotations of the word.

I'm way better in person than I am on things like Twitter. I know Twitter is the best and fastest way to connect with fans who really appreciate you but I'm still not cool with it - although I am trying! I try my best but I'm a one-on-one person and I don't want to tell people I'm on the toilet or I just brushed my teeth.

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!'

It turns out that understanding the British public is not rocket science. The British appreciate honesty and they also have a bonkers, off-the-wall sense of humour like me.

Love makes me vulnerable. In business I'm tough on myself - I'm like a drill sergeant. If I'm down, I'm used to getting right back up, but when it comes to love, your heart can't do that.

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.

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.

When you break a sweat you just feel great. You've got your endorphins going. You feel better. You look better. And if you aren't able to get a workout in, try to find a steam room somewhere. You just look and feel so much better after a sweat.
