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.

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.

Not all my shoes are designer. 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. I'm attracted to things rather than labels.

I never manage to get to bed early on Sunday night but this doesn't matter, as I don't know one level of exhaustion from another.

I was an only child, but then my parents resettled with different partners, and I am now one of six.

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