Heidi Klum has once again turned Halloween into her own haunted house of horror.

The supermodel, who hosted her annual Halloween bash in New York City on Tuesday night (Oct. 31), killed it this year by dressing up as the werewolf from Michael Jackson's classic "Thriller" video. She even documented how she did it in some Instagram videos.

This year marked the 18th time Klum has thrown the party, so her guests had to work overtime to keep up with her. A wide range of celebrities and not-so-well-known folks who managed to wrangle an invitation did their best to outdo each other while frightening the heck out of one another, so check out the costumes below to see who succeeded in scaring the pants off everyone else.
