The mother to 2-year-old Stanley also addressed the five-year gap between her third album 'Safe Trip Home 'and fourth record 'Girl Who Got Away', reported Daily Express.
"You always think you're making music, then suddenly four years has passed. Obviously I had a baby, and I was doing various things, then after Stanley came along I didn't do anything pretty much for the first year. I just hung out with him.
"I couldn't write anything anyway, all I could hear in my head was the jingle to The Wiggles. I remember my husband saying to me, 'I don't know how you're ever going to write another song again'," she said.
"You find yourself singing these nursery rhymes all day, then you're sitting at the piano, and you can't clear them out. It's strange now, juggling motherhood and my career. It's like balancing two completely different entities.
