As the spookiest night of the year approaches, the German beauty is hard at work on a costume to top her previous halloween looks – and reports reckon she could be going as Kim Kardashian!

The rumours started after behind-the-scenes snaps of a team of prosthetic experts fitting Heidi with fake boobs and a massive behind surfaced on Instagram – drawing comparisons to the famous ‘break the internet’ nude shoot Kim did for Paper magazine back in November 2014.

Heidi told People magazine: ‘I am working with Mike Marino from Prosthetic Renaissance and his team to make this year’s costume.’

The German beauty revealed: ‘They cast my entire body — eyes open! — to make the special pieces to make my costume come alive.’

And Heidi shared snaps of the full-on process a couple of weeks back, with shots showing her covered head to toe in ‘yucky’ gunk as the team went making the full-body cast.

The costume is ‘sort of a male’s fantasy,’ Heidi told People – which Kim definitely is! Although other reports suggest she could be going as Jessica Rabbit, Marilyn Monroe or even a Playboy Bunny – what do you think?

Whatever it is, one thing we know for sure is that it will be AWESOME. After all, Heidi always pulls out all the stops when it comes to her halloween costumes.

Who could forget last year’s incredible butterfly costume? Or the year her and then-husband Seal went as apes? Or her *amazing* goddess outfit?
