Heidi Klum's Halloween party is one of the hottest tickets in the US -- these photos show why it's legendary

Celebrity halloween costumes heidi klumGetty/Jemal CountessYes, that’s really Heidi Klum.

No one loves Halloween more than 44-year-old model Heidi Klum. 

Every year since 2000, Klum has hosted over-the-top Halloween parties for her famous friends — and every year she arrives in a costume that’s somehow more jaw-dropping than the last. 

She takes this stuff seriously: In fact, nobody gets into her parties unless they’re in costume. 

“I always put on my invitation, ‘Costume required,’ because if you’re not dressing up, you’re not getting in,” she told People in 2011.

Klum is already hard at work on her 2017 look  — and she’s dropping cryptic hints about it on Instagram. But until the big reveal on October 31, here’s a look back at all of Klum’s fabulous outfits over the years.

Klum was just 27 when she hosted her first party in 2000. That night, she rocked a goth Pippi Longstocking kind of look.

She kept it much simpler in 2002, dressing up as Betty Boop.

We're not sure what Klum dressed as in 2003, but man, was it shiny.

Her gold teeth and spidery lashes made the outfit surprisingly spooky.

Here's Klum as a red-haired witch in 2004. Her then-husband, Seal, was the Phantom of the Opera.

In 2005, she celebrated as a sexy (but gory) vampire.

The following year, she and Seal paired up for an adorable couple's costume. She's the biblical snake and apple, and he's Eve.

The New York Post reports that she used the costume to protect her belly -- she was 9 months pregnant at the time.

She also told the Post that she couldn't drink water while wearing this costume. Her arms didn't reach her mouth!

She spiced up the classic cat costume in 2007, adding in fangs and coloured contacts.

2008 brought Klum's only misstep: She was widely criticised for dressing as Hindu goddess Kati.

Hindu leaders said that using the likeness of the deity for dramatic effect was 'denigrating,' according to Vogue.

She played it safer the next time, dressing as a crow.

It must have been hard to eat and drink with that beak on.

Klum towered over her guests as a superhero-robot on stilts in 2010.

That glittery skin is impeccable.

In 2011, Klum had two Halloween parties (because why not?). First, she and Seal went as chimpanzees.

She planned a Cleopatra costume for 2012, but postponed the party after Hurricane Sandy hit New York City.

In 2013, Klum arrived as a 95-year-old version of herself. The look was so realistic, she had trouble getting into the party.

Klum told E! that the costume terrified her children.

The next year, she metamorphosed into a bug-eyed butterfly.

Heidi's 2015 costume started with a LOT of prosthetics.

The entire transformation took 10 hours.

But the final product -- a freakishly accurate depiction of cartoon character Jessica Rabbit -- was totally worth it.

We can't wait to see what she wears for Halloween 2016.

And in 2016 -- after an excruciating wait and lots of teaser posts on Instagram -- Klum arrived at her party as herself...plus 5 doppelgängers.

She enlisted five models and a prosthetic artist to complete the creepy look, which reportedly cost $US10 million.

Klum likely won't reveal her 2017 costume until the night of October 31. But a few videos posted on Instagram offer some clues.

Klum teased her 2017 look with a series of Instagram videos posted back in September.

The videos show Klum's hands and forearms stuck inside a green, slimy substance, as if she's making molds of them. In the comments section of the videos, fans guessed that the costume might be the Grinch, the Incredible Hulk, a mermaid, and more. We'll have to wait for the final reveal to know for sure.
