She continues to explain - "I'm 25 now and I was 18 when I wrote my first album. So however much I love Price Tag I feel a bit childish singing it now. And that's okay to say... I just live my life and I like to write songs about things I've lived. So I try to make my life as exciting as possible. Mistakes make great songs so it gives you an excuse to make them. I like to be as honest as possible and that's the most honest and sane way to be. My fans are just like me expect I like to sing."
