The 40-year-old singer, who has recruited pop star Ed Sheeran's songwriter Amy Wadge for her latest solo record, said despite having a professional on-board, she relies on her daughter's approval before the tracks get the all clear, reported Daily Express.
"Amy wrote Gold Rush with Ed Sheeran and we wrote in her shed together in Wales. I'm writing a new album and we've been doing stripped down, acoustic sets - I'm progressing to new sounds.
"My daughter listens to my own music, the way I test a really great song is to ask a child whether they like it," she said.
