If you thought Jonah Hill's epic transformation was the most impressive celebrity change-up to happen this year, think again.

Because Margot Robbie AKA the most gorgeous human to walk the planet has been spotted on the set of her most recent movie looking totally and utterly unrecognisable.

The Aussie actor has fully committed to playing Elizabeth I in the upcoming Mary Queen of Scots, donning a frizzy, bald wig and pimply, pale make-up.

A pap shot of her side profile makes it look like the 27-year-old is rocking a prosthetic nose, too, along with a heavy leather corset and collared blouse.
