(Almost) Never one to disappoint, Klum and her man were unrecognizable for this year's festivities.
The Queen of Halloween goes green!
For the first time since 2011, Heidi Klum did a couple's costume for her annual holiday party, dressing up as Princess Fiona from "Shrek" alongside boyfriend Tom Kaulitz as the title orge.
Klum is known for her intricate and over the top looks, impressing in past years by dressing as the werewolf from Michael Jackson's "Thriller" video, Jessica Rabbit, an elderly version of herself and even a skinned corpse.
For this look, the supermodel once again teamed up with the team from Prosthetic Renaissance for help with her major makeover.
She chronicled the transformation in a series of Instagram photos and Stories all day Tuesday, teasing the duo's costumes out bit by bit as the prosthetics were applied to her chest and face. Yes, those breasts are fake.
Check out the gallery above to get a closer look at the work, plus some of her best costumes from years past!
