The sexy supermodel says the 36-year-old actor - who she has been married to since July 2010 - gets an erotic kick from her feet so she makes sure her toes and soles are always in pristine condition.
Speaking to website Into The Gloss, Miranda said: "I'm really a freak about my nails. Orlando and I share a nail thing - he has a bit of a foot fetish. I like OPI's Koala Bear-y on my nails. It's not organic, but sometimes I just do it."
Miranda - who used to be a Victoria's Secret Angel - always works hard to maintain her stunning looks and figure.
The 30-year-old catwalk beauty - who has a son Flynn with Orlando - has a number of beauty essentials that she carries with her everywhere she goes, including an eye protecting lubricant to stop her pupils from being burnt on photo shoots.
She said: "I always keep my handbag packed with a few essentials. Like, I believe in dental hygiene, even on the go, so GUM toothpicks are a must. And I always keep Similasan Dry Eye Relief on me. My eyes have been burned by flash bulbs twice at photo shoots - like blisters on my eyes - so I try to keep them lubricated now. I've also got tweezers and scissors for my nails in my bag."
