From her granny style in 2013 to the acute body hair problem she suffered in 2011, there's nothing dull about Heidi's costume choices. In fact, the supermodel is usually unrecognisable when she hosts her annual parties - and this is exactly why she's the queen of celebrity fancy dress.
Need a recap of Heidi's Halloween history before you find your outfit? Let us take you through the highlights...
Heidi was the forbidden fruit from the Garden of Eden. Her then husband Seal was er, Eve.
Probably one of Heidi's more normal costumes, she disguised herself as a black cat to host a Halloween party at The Green Door in Hollywood.
The skulls, the arms, the blood-soaked limbs - this outfit from Heidi's New York Halloween bash had it all.
For her first public appearance after the birth of her daughter Lou, Heidi dressed up as a crow. Of course she did.
Now this is how you do superhero.
Heidi's acute hair problem was followed by the exact opposite when she showed off her second costume of the year. In her own words, she looked like "a dead body with the first layer of skin ripped off." Lovely.
You'll never see a better Cleopatra.
Make up maestros Bill Corso and Mike Marino worked their magic on grandma Heidi.
No one does Halloween better than Heidi - but she's not the only celebrity who puts in the effort...
