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.

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

Getting up to dance to your own stuff looks pretty pretentious. And leaving the dancefloor when it comes on is just awkward.

I'm a little bit allergic to the whole brand thing to be honest but maybe it's just happening around me and I'm not really aware of it.

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 don't think anyone doubts my motives, really. I do what I do and it's not very complicated. Of course, you might hate the music that I make, but I don't think people feel threatened by me just getting on with what I'm up to.

It's funny how intimate it feels to get a text.
