The 45-year-old singer says her glamorous look is just for show, reported Daily Express.
"I'm a complete letdown. At home the stilettos come off. The comfy clothes go on. I'd love to maintain this illusion that I kind of elegantly waft around at home or something but I need that balance in my life, to just be completely anti-fashion and put on whatever is closest and home is the place to do that," she said.
Minogue has compiled some of her best stage looks in a new book, Kylie Fashion, to celebrate 25 years of her style through her career, and revealed things often get heated backstage when she has to get changed quickly.
