It's usually a big kind of vent of frustration or anger or sadness that puts me in the right frame of mind to write. It's such a cliche to say that artists write when they're down, but it's true for me. It's a relief to get out what's eating away at my heart or my soul or my head.Collection: Anger
I instinctively dress a bit tougher because I've spent a lot of time in the U.S. and I realised there was a certain image projected of me here. I've always been an absolute rebel. When I was in my teen years I had piercings and wore all black.Collection: Teen
I was super brainy and a proper geek at school, but there would always be a boy. But that sort of obsession did turn me into a songwriter. My writing has always come from that feeling of infatuation.Collection: Brainy
I suffer panic attacks which has made me really conscious about my fitness and I have become addicted to jogging. It might sound odd but a lot of good has come out of it. My fans send letters saying they have taken up jogging because I do it.Collection: Fitness
I'd like a male to listen to my music and find it kind of fascinating, what a girl goes through when they get heartbroken or get sad or get hurt by something.Collection: Sad
Even when I'm in quite a happy state of mind, I like writing really sad songs. I think a lot of people do.Collection: Sad
I met Prince William at a musical festival and he let me know he was a fan of my music. But the invitation to sing at his wedding reception came completely out of the blue. The fact that Kate and William knew the words to my songs was very touching.Collection: Wedding
I want to be safe in the knowledge that I can tour and play festivals for a long time. The main thing is that I want a good reputation as a live performer. If I have that, I'd be so happy.Collection: Knowledge
'I Know You Care' is about my dad. And I haven't seen him for a long, long time. And my parents divorced when I was really young. And I guess I just wanted a - it was my way of saying that I wasn't bitter or angry anymore. I was just sad and just felt like something was missing.Collection: Sad
Christmas in L.A. is weird. There's no snow. It's not even cold.Collection: Christmas
I record stuff all the time, like little vocal things. I write random things down... Sometimes I just get things stuck in my head and I record them, and that actually becomes a song quite a lot of the time.
I find male singers and what they sing about fascinating. It makes me realize how little we know about ourselves and how little I know about myself. It's interesting to see the male perspective.
When I heard Bjork's debut, that was when I first realized that I could be a singer, even with my unusual voice.
Lauryn Hill is quite political and is very bold and isn't afraid of wearing her heart on her sleeve, and same with Bjork, except she is a little bit more kind of fragile.
I think all the covers I do have nice sentiments, particularly 'Your Song.' People write me very sweet messages about that song, though I'm sure there are people out there saying that I've ruined it too!
I never remember having a plan. All I could think about was how I was going to afford to get into college or where I was going to stay because I hated being at home. I didn't really have time to think about anything in the future. I didn't think about a career or anything. I went to uni, got a couple of jobs, so I sort of funded it myself.
I could always sing, from a really young age, but my voice was really weird. I used to make my mum turn up the radio every day in our house. She was well into music so I got that from her.
I couldn't really relate much to my younger sister, because she was born in 1992, and I was born in 1986. And then my older sister, we just didn't get on that much. Although we bonded over hating our stepdad.
I maintain that when I finally retire from my career in music, I will go and live back in Wales - when I am an old person, if I live to be an old person. The water I miss, and the air, there's something different about it. And I miss the simple life.
I'd hate it to become style over substance, I'd hate people to start putting me in a magazine article about my style. I don't like dressing up in something I'm not necessarily comfortable in just to make it more of a show. I want the power to come from what I sing about and how I sing.
I guess I started running when I was about 18 and... I feel like it assists my creativity a bit because it completely just flushes everything out.
My favourite people to follow on Twitter are... my fans. They make me laugh so much and keep me smiling.
My guiltiest pleasure is... chocolates with strawberry cream and trashy television - 'Geordie Shore,' 'Katie,' etc.
Two things I'm obsessed with are the countryside and fields and being in the open space and body parts, so you'll hear me mentioning body parts and human anatomy. I've listened to my songs and I think I am quite visual and I talk about bones and flesh a lot.
I want to be more like Pixie Lott. She works really hard but always manages to keep smiling. She never complains.
Because I've always been a runner I love to feel that my body is shining on the inside. I wear baggy clothes, so it's not as though I like showing it off. I just like to know I'm great on the inside.
Men are wary of me because they know, by listening to my music, that a relationship with me will be quite deep.
I never thought that I could make a living out of my voice, to be completely honest. I thought that I could probably keep playing pubs. And it was exciting for me to get even just a pub gig in my town or country, when I went to university.
I've changed the way I look a bit but not intentionally. I've cut my hair. I've got a bit of pink in it and lately I've become a bit monochrome, wearing a lot of black and white.
I hadn't even released my first proper single when I started to feel the strain of attention. But I don't believe that it was the attention that was giving me panic attacks. I think it was everything in my life colliding at the same time. It really did get to a serious point where I couldn't even walk down the street without getting the pain.
You pick up loads of baggage with your first record with reaction to it from fans and critics. So I went to Ireland by myself for a couple of weeks with my guitar. I read lots of poetry, I read Patti Smith's autobiography and started words and phrases and then songs started to take shape.
You should constantly write because your writing is always evolving and progressing. It's really important to start writing young.
Gwen Stefani has amazing style. I used to really love Courtney Love, and anything she wore I loved. Or Chloe Sevigny, because I really love that sort of classic look, and I like being girly and flowery, and wearing little D&G dresses. I wear hats a lot, too. I think it goes back to when I was a bit grungy and was a skater girl for a bit.
I still love the skinny jeans thing and I wear my favorite leather jacket constantly. I like being kind of a rock star. I love that I can feel comfortable in a small dress or I can feel comfortable wearing a baggy T-shirt.
I'm obsessed with the countryside: woods, forests, fields, lakes, mountains. I'm really into folk music and folklore. But more so I'm into electronic music. I'm into bands that have both aspects, like Boards of Canada is a perfect example. You could listen to that type of music running through a woods. It's kind of what I wanted to achieve.
After shows my face feels dirty with makeup and sweat, especially in the smaller venues, so it feels good to get back to the bus and smooth it away. Sometimes you need something alcohol-based, especially on tour when you don't always get a chance to keep washing your face all the time.
It's so important to take vitamins. People always get ill on tour because of the close proximity in the bus with everyone.
Breakups just hit you harder when you're younger. When I was a teenager, it felt like the most depressing thing in the world if a boy I was infatuated with didn't like me back!
I don't really have a style icon but I really admire the way people dress like Gaga, Rihanna and Gwen Stefani. It's good to be inspired by singers who write music and dress incredibly - rather than models and people in the fashion industry who dress immaculately anyway because it's their style.
Every day I'd say I look different. Sometimes I look really formal, sometimes I love the classic Stella McCartney, Chloe Sevigny and Gwyneth Paltrow thing. Other days I like being rock star and wearing leather jackets and studs. I love wearing Burberry - it's the perfect combination of formal and punky.
I feel like my figure is a challenge because I'm quite flat chested but I've got a booty so I've got to look for the right things.
On stage I have to be comfortable because I play guitar so I can't wear too much jewellery, it knocks against the guitar and makes loud noises. I had this big gold eagle necklace which I love but I kept whacking myself in the face with it so had to stop wearing it. I wear things that I can sweat in, basically... it gets really hot on stage.
