The host of Project Runway is known not just for being a hugely successful supermodel, but also for her outrageous Halloween costumes.
The 42-year old is getting preparations underway very early this year as she gave her fans a sneak peek at her costume.
It involves, blue goo and very little else.
The model stripped down to almost nothing as bared it all so she could be completely covered in weird blue-grey goo. That is extreme dedication to the cause.
The goo was necessary to produce a body cast of the model, which she posted on her Instagram account.
We can’t imagine we would be too delighted to be covered head-to-toe in the weird looking concoction whatever floats your boat Heidi!
To be fair, she has set a very high standard for costumes in the past and is probably the A-Lister many people look to for some inspiration at this time of year.
Remember her incredible butterfly costume?
There was also the time she aged herself to the point of looking almost unrecognisable.
There was also her 2006 Garden of Eden styled costume.
Two years later she took it to another extreme entirely with her epic Hindu goddess costume.
