We're calling it: This is Heidi Klum's best Halloween transformation yet.

Heidi Klum is the undisputed queen of Halloween.

The model and Project Runway host, 45, has been hosting her #HeidiHalloween parties since 2000 and has been wearing increasingly epic costumes each year since.

This year marks 19 years of her parties and costumes, so you know Klum had to go big.

After days of teasing on Instagram, and sharing her previous costumes as part of a #HeidiHalloween countdown (this is soo extra, we love it), Klum and boyfriend Tom Kaulitz finally arrived at her 2018 Halloween party as Shrek and Princess Fiona.

And it is amazing.

If you're thinking 'How the HECK did Heidi Klum transform herself into an ogre?' then wonder no more, because Klum showcased the painstaking process on Instagram - because of course she did.

We have a few questions: Like did Princess Fiona really have such a large chest? Can she breathe with that nose prosthetic? And also... How did she use those GIANT ogre hands?

Logistics aside, this is incredible.

Klum has pulled out some truly extraordinary costumes in the past, like when she literally learned to walk on stilts for her costume in 2010, or the time she was an eight-month pregnant apple.

See? She's a Halloween legend. But we think her Princess Fiona tops the lot.

Of course, attending Klum's annual Halloween bash comes with a lot of pressure.

Her guests certainly brought their A game or uh, their sass: Mel B dressed as Victoria Beckham.

We're already excited to see what Klum does for next year's 20th year of #HeidiHalloween.

Here's to many, many more years of ridiculously OTT costumes.
