Forget zombie cheerleaders or skeletons, several celebs decided to ditch the traditional scary Halloween costumes this weekend.
Instead, they took their inspiration from iconic movies and famous music legends.
Kim Kardashian led the way with three dramatic looks, while Adele made a rare appearance on social media to mark the scary weekend.
Here Newsbeat brings you a round-up of the best celebrity Halloween costumes so far.
