The 40-year-old "The Black Eyed Peas" vocalist said she could not afford to wear heels much, as she need to take care of her som Axl, reported People magazine.
"Well the heels are lower, because it's just not possible - it's not safe - to be in stilettos all the time when you're running around after a two-year-old. But it's actually more special now when I put on a heel. It gets me into sensual mode if you will," Fergie said.
