Heidi Klum has established herself as the queen of Halloween with her spectacular annual soirée and equally amazing costumes. The supermodel consistently outdoes herself with incredible ensembles that often render her unrecognizable — she's dressed up as everything from a gigantic butterfly to a creepy cadaver and all things in between.
And her latest look just might be her most outrageous yet!
For Halloween 2019, the reigning costume queen brought everyone's sci-fi/horror nightmares to the waking world with an elaborately gory cyborg getup.
It took a lot of time and effort to make the gorgeous supermodel appear grotesque — and fans were able to watch the 12-hour process before Klum kicked off her 20th annual Halloween bash.
Some witnessed the transformation live at the Amazon store in New York City, while others looked on as the 46-year-old documented the grueling, prosthesis-filled process on Instagram.
In the clips, Klum smiled, laughed and even ate dinner while being glued into her brain-exposed alien outfit.
And that wasn't even her first costume of the season!
Last weekend, Klum attended Paris Hilton's Halloween party with hubby Tom Kaulitz. The newlyweds packed on the PDA and lit up the night as a pair of glittery fireworks.
Klum brought on the sparkle in a dazzling dress, plenty of body glitter and green locks, while her other half painted his face and beard in glitter.
We can't wait to see what next year has in store. Until then, here's a look back at Klum's impressive collection of Halloween costumes.
2001: Lady Godiva
Klum sure knows how to make an entrance! For her first annual fête, the model showed up on the back of a horse, just like the legend of Lady Godiva. Her bloody countess costume included an all-white ensemble and long golden locks. All that was missing was Peeping Tom!
2002: Betty Boop
Klum brought the cartoon character to life with a black wig, vampy red dress, plenty of bling and over-the-top eyelashes that totally stole the show!
The supermodel took a journey to outer space in 2003 and brought back a fully gilded look complete with metallic armor and a fierce helmet.
2004: Red witch
Klum put her own creative spin on the classic witch costume, opting for an all-red outfit, matching hair and a skeleton in place of a broom. We're sure guests were bloody scared of this sexy sorcerer!
Klum took the bloodsucking beast to a new level with fangs, thigh-high boots and a bleeding heart. We're sure this glammed-up version of the undead was a total hit at her annual event.
2006: Garden of Eden
A pregnant Klum found the perfect way to conceal her baby bump — inside a giant apple costume! The model made a compelling case for living in sin, incorporating a slithering serpent into her Garden of Eden-inspired getup.
In 2007, the supermodel wore a velvety cat suit that played up her curves. It was definitely one of Klum's tamer Halloween looks, but her spot-on makeup and perfectly placed fangs were all pretty darn purr-fect.
Klum’s interpretation of the Hindu goddess Kali was as over-the-top as it gets. Between her blue skin and the creepy artifacts her multiple arms were carrying, the costume was certainly a sight to behold.
Klum and then-partner Seal wore matching crow get-ups with black feathers and oversized beaks in 2009. The model's costume definitely gave a bird's-eye view of her gorgeous gams, too!
Klum makes a convincing superhero! Her red and purple Transformer costume was a robot-lover’s dream and made her tower over her party guests at 8 feet tall.
Klum celebrated Halloween on both coasts in 2011, showing up to her Las Vegas party as a cadaver. The model was wheeled into Tao nightclub on an autopsy table, just in case the “dead body” look didn’t freak out guests enough!
Back in New York City, Klum and Seal donned the most realistic ape outfits we’ve ever seen. The model was covered in fur and sported a lifelike mask. My, what big ears she had!
After Hurricane Sandy in 2012, Klum hit pause on Halloween and postponed her NYC party until December. While the model sparkled from head-to-toe in a glittery gown, cape and headdress, the standout element of this costume was the hundreds of crystals covering her face.
2013: Old lady
The supermodel outdid herself in 2013 with a make-under that made her tough to recognize! Complete with varicose veins, wrinkly skin, silver locks and a cane, Klum took granny chic to a new level.
Klum transformed into a butterfly, displaying vibrantly colored wings and bug eyes for her party in 2014. We're sure it was pretty tedious to sit through hours of body painting, but the end result was truly a treat.
2015: Jessica Rabbit
Leading up to her annual party, Klum spent hours in prosthetic fittings to help her mimic Jessica Rabbit's curvaceous figure. With on-point hair and makeup to top it all off, this va-va-voom look was one of Klum’s most impressive costumes yet.
2016: Six clones of Heidi Klum
In 2016, Klum put the trick in "trick or treat" when she showed up with five clones of herself. She even added prostheses to each lookalike's face to make it even harder to tell them apart.
2017: Michael Jackson as a werewolf in "Thriller"
Klum sent chills down our spine when she channeled Michael Jackson's "Thriller" music video. It would have been memorable if she dressed as the iconic pop star, but she took things one step further and went as the bone-chilling werewolf Jackson becomes in the video.
2018: Princess Fiona from "Shrek"
The queen of Halloween transformed into Princess Fiona from "Shrek" in 2018, complete with green skin and pointy ears. She also brought along her main squeeze, then-boyfriend Tom Kaulitz, who channeled the film's funny namesake.
