The supermodel and TV personality dressed as Princess Fiona from "Shrek" for her 19th annual Halloween party on Wednesday.
Lynn Tremblay, a woman from Ottawa who signed the petition, said moving Halloween to Saturday would give her more time to prepare for it.
She paired the iconic green skin with Fiona's signature ginger braid and crown, glamming up the look with some sparkly eye shadow and fake lashes.
Heidi Klum and her boyfriend, Tom Kaulitz, have transformed into Shrek and Princess Fiona for the supermodel's annual Halloween party in NY.
The famed host has been planning the costume for months, and teased a collaboration with the company Prosthetic Renaissance Inc.in September. She revealed, "I said, 'Babe, what do you think about being my Shrek?' and he said, 'Yeah, I'd love to be your Shrek.' He was pretty much on board immediately, so I was very excited about that". The pair arrived in a fairy-tale style chariot and even pushed a pram with little ogre babies in it.
Unsurprisingly, this year's look did not disappoint her fans, one of whom tweeted that she "cannot be beaten" when it comes to Halloween. Naturally her 29-year-old rocker boyfriend, Tom Kaulitz, was dolled up as lovable ogre Shrek.
This year's bash was sponsored by SVEDKA Vodka and Party City.
