The 38-year-old singer, who has a three-year-old daughter Scarlett with partner Thomas Starr, said whenever she looks at the kid she feels it is the best thing to have happened to her, reported Contactmusic.
"It's like a ray of sunshine every day. I think the best part of my day is waking up in the morning and going to see her, then having breakfast together.
"There's no doubt it's the hardest job in the world and there are moments when it is so, so tough, but you can't get over how brilliant it is having a new person in your life who is so young and energetic.
"It's getting harder as Scarlett is starting to form her own opinions," she said.
