In her latest nuude shoot, Kim posed perched in a tree wearing nothing but black boots which, according to Mert Alas, makes her a "Night Bird".

The black & white photograph features in well known photographer duo Mert Alas & Marcus Piggott's new art book, set to be released on 7 Sept.

According to Kim's caption alongside the photograph, the book has been in the making for 20 years.

Gigi Hadid is one other model who will be featured in the book.
