My biggest downfall is my inner voice. Growing up as a dancer makes you very judgemental with yourself. You learn to look at yourself in the mirror and you criticise every line in your body. It's never perfect. I grew up with this because I had ballet every day in school.

I'm not one of those people that has to look myself up every five seconds to see what people are saying. That's been really helpful. I mean, you get thousands of compliments, and then one person will say something negative - and that's all you'll remember, that one person.

The paparazzi have got worse for everyone over the years. It has just become such a big deal. No-one in this business really has much privacy.

If you are thinking every day, 'I have to get to the gym' and 'I have to lose this weight,' and that's all you think about and you obsess over it, it's not healthy.

I was performing with the Pussycat Dolls when I was approached by a company who wanted to do a workout series. I hired the creator of the Dolls, and as a team we went in and rehearsed and put together this series.

It's sad. That's a living creature. We don't have the right to take their life away for fashion.

Being flirty is a way of letting a guy know you're interested without making a fool out of yourself.
