In the past, she's dressed up as everything from Lady Godiva to a transforming robot.
And it's what makes Heidi Klum's annual Halloween party such an institution.
The queen of fancy dress is obviously getting excited already, posting a flyer for the do on Twitter.
"Halloween Countdown! 22 days until @taolasvegas!" she wrote.
The German beauty usually manages to rope her husband – British soul singer Seal – into the fun too, with the pair of them sporting equally fantastic costumes each year.
Heidi's guests are also encouraged to get into the party spirit and make sure their outfits look equally spectacular.
This year, her fright night will take place at Tao nightclub in Las Vegas on 29 October.
