Singer Mariah Carey has shared an image of her huge shoe collection on the digital platform, and says it's her "favourite room in the house".

The 45-year-old singer took to photo-sharing website Instagram to flaunt a tiny portion of an entire room dedicated to her shoes. She even revealed that she has at least 18 shelves just for gold heels, and at least four for knee-high boots, femalefirst.co.uk.

Carey tweeted: "Always my favorite room in the house #shoes #shoes #moreshoes (sic)".

The "Hero" singer has also previously said that she doesn't even take them off to go in water.

"I swim in evening gowns and heels," she said.
