The supermodel has form for taking Halloween very, very seriously.

This time last year we brought you images of Heidi Klum and her very creepy ‘Klones’, and not one to rest on her laurels, she outdone herself again this year.

She documented her transformation into a werewolf, which required a team of 5 special effects artists, 7 hours of work and a whole range of prosthetics, on her Instagram account and the results were amazing.

There’s no black bin liners, recycled egg boxes or a slap of face paint for Heidi.

Watch the transformation below:

A work in progress.

And the finished product. Wow. That's an 'A' for effort.
