Celebrity Halloween Costumes 2023: Keke Palmer, Kourtney Kardashian, and More — See Photos

Spooky season is here, and there's no better way to celebrate than sitting back with a pile of candy and judging celebrity Halloween costumes. You might just think of the perfect look to recreate for Halloween next year (like an adorable Sonny Angel) or witness an unforgettable meme be made in real time (like NCT 127's Twilight moment).

Celebs have taken Halloween very seriously this year, with some beginning to post their costumes as early as mid-October. We expected no less from master organizer and party planner Khloé Kardashian, who celebrated her annual pumpkin decorating event in adorable matching cow costumes with her children. Ariana Grande stuck with a classic look for her intimate Halloween party. Hailey Bieber hopped on the early train as well, sharing not just one but two costumes before the big day. If you've been wondering what celebs have in store for Halloween this year for a while, wonder no more, and let's dive into the best celebrity Halloween costumes of 2023.

We'll also probably see some late stragglers sharing their costumes a few days into November as well, and there's no shame in that. To help you keep up with the inflow of festivities, we'll be compiling all the best celebrity Halloween costumes of 2023 here, so make sure to keep refreshing to see what you missed. Scroll on to see your favorite celebrities' Halloween 2023 costumes:

Kourtney Kardashian as Met Gala Kim Kardashian

Kourtney Kardashian shocked fans by dressing as Kim — the sister she's famously had the most tension with in recent years. Despite the in-family fighting, a very pregnant Kourt opted for Kim's iconic Met Gala look from 2013. Much like the sister replica, Kim was pregnant with North when she wore the floral Givenchy gown to fashion's biggest night of the year.

Hailey & Justin Bieber as Pebbles Flintstone and Bamm-Bamm Rubble

The Biebers attended their first Halloween party very much dressed for the same occasion as Pebbles Flintstone and Bamm-Bamm Rubble, two of the youngest characters from The Flintstones.

Hailey Bieber as Carmen Electra in Scary Movie & Mean Girls characters

Hailey also had her major solo moment, tapping into a camp horror classic and channeling her inner Carmen Electra from the Scary Movie's iconic opening scene, which famously spoofs Scream.

Justin Bieber as a Snorkeler

Justin Bieber's got his swim trunks and his flippy floppys. The musician attended the star-studded Casamigos Halloween party in Los Angeles wearing what appears to be a snorkeler costume. Bieber was shown in flippers and a snorkeling mask, along with a pink flowy shirt and shorts.

Paris Hilton as “Toxic” Britney Spears & Mushroom Katy Perry

Leave it to Paris Hilton to honor Britney Spears in the best way. The heiress and social media icon dressed up in Spears' flight attendant outfit from the “Toxic” music video. Wearing a long ponytail in the back, much like Spears did, Hilton stunned in the blue getup. “In honor of our Queen,” Hilton wrote in the caption under a video of her walking to the opening of “Gimme More.”

For her second Halloween costume, Paris Hilton also tapped into the pop-culture archives by dressing up as Katy Perry in her SNL mushroom outfit.

Ice Spice as Betty Boop

North West as Kanye West (Sorta)

Much like Kourtney Kardashian, North West is keeping it in the family this Halloween. The 10-year-old referenced one of her dad Kanye West's most notable albums, Graduation, by dressing like the cartoon bear on the cover. In several videos posted on the official Kim and North TikTok, North can be seen dancing around to Kanye's music with the bear costume on.

Keke Palmer as the bride of Frankenstein & Life-Size's Eve

Keke Palmer went classic yet spooky this year, dressing as the bride of Frankenstein. And who played the role of Dr. Frankenstein? Her son Leodis — goggles and all.

For her second costume, which was a two-parter, Keke transformed into everyone's favorite doll-turned-human Eve from the ‘00s classic. She recreated the movie’s poster to perfection and even got Tyra Banks's stamp of approval in the comment section. “I thought this was ME! But girl, you look better!!!!” the OG Eve wrote.

Adele as Morticia Addams

Adele hit the stage for her Las Vegas residency on Friday night in a Morticia Addams get-up. Wearing a long black wig and hip-hugging gown custom made by Arturo Obegero, Adele was the picture-perfect Addams matriarch.

Dylan Mulvaney as Snow White

Dylan Mulvaney chose one of the most classic Disney princesses as her Halloween costume this year. With the new live-action Snow White film right around the corner, it was fitting that Mulvaney get ahead of the trend.

Chlöe Bailey as Daenerys Targaryen & Catwoman

Chlöe Bailey is the Mother of Dragons. Bailey gave us her own take on the Game of Thrones character complete with a long blonde wig and dragon eggs. We can definitely feel the heat from this photo.

She switched up the next day with her own take on Catwoman. The evil is in the details with this one.

Megan Fox and Machine Gun Kelly as Kill Bill & Death Note Characters

Megan Fox and Machine Gun Kelly really nailed it this year for their couple's costume. The pair dressed in characters from Kill Bill — Fox dressed as one of the villains from the film, while MGK dressed as the main character played by Uma Thurman.

The couple also tapped into anime, more specifically Death Note, for their second costume. MGK dressed up as shinigami Ryuk while Fox was a gender-swapped Light Yagami.

Austin Butler and Kaia Gerber as Andy Warhol and Edie Sedgwick

Austin Butler and Kaia Gerber's couples costume was inspired by two real icons: Andy Warhol and model Edie Sedgwick. The wigs really added to the charm for the A-list pair.

Rosalía in Björk's Iconic Swan Dress

Rosalía is a fashion girlie, and her Björk swan dress is the perfect proof. Even the shoes were identical. (Lest we forget that the Spanish and Icelandic singers recently teamed up for a song to denounce fish farming in Iceland, do we think she got styling tips then?)
