All Of Your Favorite Celebrities' Best Halloween Costumes Of 2019

While you may sometimes wish you had a chance to be famous, even celebrities use Halloween to be someone other than themselves. When it comes to this year's best celebrity Halloween costumes, the biggest trend has no doubt been stars dressing like fellow famous people or TV/movie characters. For the past week, Ariana Grande has been posting clips of the Twilight Zone as a build-up to her costume reveal, and last weekend Jessica Biel dressed up as her own husband Justin Timberlake back in his *NSYNC days.

There are also a few other key takeaways from celebrities' Halloween 2019: Kylie Jenner has shown there's no limit to the number of costumes you can wear (she's already dressed as a Playboy bunny, the Little Mermaid, and Marilyn Monroe), Demi Lovato is proof that makeup can make you completely unrecognizable, and Jennifer Garner set an example in thinking outside the box... by dressing up as a mailbox.

From couples costumes to pop culture throwbacks, here's a roundup of your favorite celebrities' Halloween outfits — just in time to give you last-minute inspiration. Proceed with caution, though, because you might not be able to unsee some of the spookier looks.

1. Ariana Grande Pays Tribute To the Twilight Zone

This year, Grande dressed as a character from the Twilight Zone. The costume, from the "Eye of the Beholder" episode, featured a young woman who undergoes multiple cosmetic surgeries to finally look like everyone else.

Hosting a star-studded party, Grande gave a tour of her home post-Halloween treatment.
