“I'm way better in person than I am on things like Twitter. I know Twitter is the best and fastest way to connect with fans who really appreciate you but I'm still not cool with it - although I am trying! I try my best but I'm a one-on-one person and I don't want to tell people I'm on the toilet or I just brushed my teeth.”
“I'm going to take care of the man I'm with. I grew up in a household where my mum takes care of my dad - she cooks, she does everything - and that's the kind of girl I am.”
“I was a shy kid, but somehow I knew I would make it as a performer. I'd always be telling my mum that I was going to be a famous singer. In my school yearbooks I would write, 'Remember me when I'm famous.' I knew I had a gift.”
“I don't really believe in diets. I love food... If I deprive myself, I'm going to want it more. I snack on yogurt, raw cashews and cherry tomatoes.”
“I love a man with a great sense of humor and who is intelligent - a man who has a great smile. He has to make me laugh. I like a man who is very ambitious and driven and who has a good heart and makes me feel safe. I like a man who is very strong and independent and confident - that is very sexy - but at the same time, he's very kind to people.”
“Growing up, my mom was very strict about how I dressed and how I behaved, and I said to myself that I wasn't going to be like that. But now I know I'm going to be exactly like my mom. I'm going to be worse!”
“A lot of songs are empowering because everybody who has been through a hard time in a relationship or in their lives can relate to it.”
“Although religion was around me my whole life I never felt it was forced upon me. It is my centring, my grounding, the soul of me. I feel I'm nothing without it.”
“It turns out that understanding the British public is not rocket science. The British appreciate honesty and they also have a bonkers, off-the-wall sense of humour like me.”
“Girl power is about loving yourself and having confidence and strength from within, so even if you're not wearing a sexy outfit, you feel sexy.”
“I've always been too hard on myself to behave like I've arrived or even to enjoy whatever success I've had. I've always envisioned myself higher than where I was and I still do. With each success I think, 'That's nice but I'm supposed to go there!'”
“My bulimia was my addiction. Hurting myself was my addiction... The music is what saved me. That's the only thing I can trust.”
