The countdown is officially on! It’s time for the spookiest time of the year – and plenty of celebrities are already getting on the Halloween action in their most epic, jaw-dropping costumes.

Popular contenders on the Hollywood list include Anne-Marie, Nina Dobrev and Jameela Jamil channeling their inner Billie Eilish, Kourtney Kardashian dressing up as our ponytailed princess Ari, and Stormi Webster cosplaying as Kylie Jenner’s fabulous mini-me in her famous Met Gala gown. On the Hallyuwood side, we’ve got the TWICE girls transforming into movie characters such as Maleficent, Genie from Aladdin and more.

I’m dressed as Silly Eilish, the weird third sibling they didn’t tell you about…. 🎃 Frightfully good fun DJ’ing preview night for @Spotify’s Halloween costume pop-up, open on Saturday. Being a little scary isn’t a bad thing, come celebrate the boldness of artists and grab a costume accessory while you can. #stayscary #spotifypartner
