I've got quite a curvy shape so I try to wear stuff that's tailored.

In real life, I'm not super-posh but if that's the stereotype, I really don't care. It could be worse.

In terms of clothes, everything is on the same level for me. If I like it, it doesn't matter if it cost £200 or £2.

It's hard to feel comfortable in your own skin when you're younger.

My little boy Sonny makes me laugh all the time. He has good comedic timing.

My parents are good role models because they've worked hard and gave me a happy childhood.

Some people are really good at packaging themselves, but that's not really me.

'The X Factor' is great entertainment, but it doesn't prepare people for getting chewed up and spat out by the music industry.

There are a lots of clowns in our family - our house is a fun house.

Turning the thermostat down is something that I do pretty reluctantly. I like to be able to walk around in whatever I fancy at home.

When it comes to my family I never quite know how protective I have to be, or what I should or shouldn't say.

Writing songs about fancying people in dance clubs is all very well but it's not the be-all and end-all. There are other topics.

Yeah, I'm not really a morning person.

You learn that, when your children are all right, everything is right in the world.

You need to have a life outside your career.

I can definitely tell when mum has got money because then she likes to go shopping to spend it, whereas dad is steadier and avoids splurges. I like to think I've inherited both sides.

I don't want to sound like an old grandmother but actually it's quite nice when you get up early and then, by the time it gets to 10am, you're quite perky and already quite switched on.

I love getting dressed up. Being a pop star is the most brilliant job for that. A lot of girls love shopping, but they might see the most amazing outfit and think, 'When am I going to wear that?', so it's my duty to exploit the fact I do have events I can wear these things to.

I tasted huge success with my first album, and when it's happening it feels like a roller coaster you can't get off. You should be very careful about wishing for success on that scale.

In terms of influence, my style icons have been a mixture of Julie Andrews and Olivia Newton-John. When I was little I used to watch 'Grease,' 'Mary Poppins' and 'The Sound of Music' a lot. If you put all those things together you do kind of get my outfits. A slightly tarty nanny in a second-hand outfit. That is pretty much what I wear.
