The saucy star stripped off to the kinky custom-made footwear, complete with suspender belt.

She uploaded the picture – taken by a mystery snapper in her bathroom – with a caption praising Italian designer Miuccia Prada.

And she wrote: “Gotcha bitch tip toeing on my marble flo’!!! Sick ass custom Prada boots! Miuccia you RULE!!! Thank you.”
