The supermodel, 46, who’s known for her extravagant costumes each year, appeared to bare all in a bizarre body suit outfit.
It is the latest in a long line of startling guises – with previous Halloween costumes including the werewolf from Michael Jackson’s Thriller music video and Princess Fiona from the Shrek films.
For this year’s zombie-like ensemble, she spent hours having a team of experts transform her into a bizarre Frankenstein’s monster-like creature.
Using prosthetics and make-up, she was left with convincing exposed flesh and muscle alongside patches of skin sewn together.
She also had metal spikes pushing out of her spine and her exposed “brain” protected by glass casing.
