“A fan sent me a pair of fluffy winter socks, and I was like, 'Oh, that's cool. I'll wear them to bed. It's cold; it's winter.' But they were worn. They were black underneath, and they stunk, and I hate feet. She was like, 'I'm giving you my favorite pair.'”

“I just love mermaids. I was a mermaid in my past life. I just feel it when I go in the sea. I just feel a connection there between me, and the water, and the fish - they speak to me - and the shells - they ring out to me.”

“I knew from the start that I wanted my life to be about music. I taught myself the notes of the piano aged three, and then I spent the next few years deconstructing chords to figure out how to play them.
