Megan Fox and Machine Gun Kelly attend the Annual Casamigos Halloween Party on October 27, 2023 in Los Angeles, California.

Halloween is the best holiday for a number of reasons: you get to watch scary movies the whole month leading up to it with no judgment, you can stuff your face with the candy you “bought for trick-or-treaters,” and you can dress up as whatever you want to be. Halloween for the rich and famous takes the latter to the next level, leading to some very elaborate get-ups. Prosthetics and wigs are just some of the tools Hollywood’s elite transform their Halloween costumes to become memorable inspirations for years to come.

Heidi Klum is probably the most popular celebrity when Halloween season comes around. She hosts a major Halloween bash and goes all-out year after year with her costumes. Over the years, she’s dressed up as Cleopatra, a butterfly, a vampire, a dominatrix, Lady Godiva, a witch, Betty Boop, Jessica Rabbit from Who Framed Roger Rabbit? and a worm. Megan Thee Stallion hosts her annual Hottieween party, and the young rapper goes all-out as well.

However, celebrities don’t have to host parties to be known for their creativity in Halloween costumes. Kourtney Kardashian loves Halloween and does multiple looks for the holiday. Megan Fox and Machine Gun Kelly wear coordinating costumes. Billie Eilish has dressed up as some kind of niche character that no one else is doing. Then, there are stars who honor other icons in the industry by dressing up as them.

Regardless of who it is, there is something about seeing who or what famous people dress up as for Halloween that we can’t get enough of! Dressing up is already fun to do, but on Halloween, you can dress up as anything and really let the imagination run wild. That’s why it is our favorite holiday of all time. Take a look at which celebrities have the hottest costumes of 2023:

  • Megan Fox and Machine Gun Kelly

    The Jennifer’s Body star dressed up as Gogo Yubari, a severely disturbed teenage schoolgirl who gets a huge thrill when it comes to killing for fun in Kill Bill: Volume 1. The actress went all-out with her costume, with bloody tears, extra long red nails, and a chain ball purse. MGK was The Bride (Uma Thurman), wearing a bloodied-up yellow jumpsuit, holding a katana (sword).

  • Kendall Jenner

    The model dressed up as the iconic Marilyn Monroe this Halloween. Jenner wore a gorgeous short curly blonde wig. Even though her costume was pretty simple with a black turtleneck and white satin skirt, Kenny looked gorgeous as Marilyn.

  • Adele

    During weekend 33 of her Weekends With Adele Las Vegas residency, the “Send My Love” singer entertained fans dressed as Morticia Addams. Fans have expressed wanting to see Adele star in her own vampire flick, and this costume gives them hope. With a black wig, iconic smoky eye makeup, and expensive-looking rings with a bloody manicure to match, Adele looks amazing as Morticia.

  • Paris Hilton 1

    Honoring Britney Spears, Paris had fun dressing up as the flight attendant from Britney’s “Toxic” music video. In another post, she holds up a phone wallet to her ear to emulate Spears’ character from the music video. Her son, Phoenix, and her husband, Carter Reum, dressed up as pilots to match the heiress.

  • Paris Hilton 2

    Honoring another one of her iconic queens, Paris threw on a black wig and mushroom hat, paired with a red latex sexy ensemble to evoke her inner Katy Perry when she wore the same outfit for her Saturday Night Live performance in early 2022. Posting side-by-side images between her and Perry, Paris really nailed every detail, even the fringed chaps! Bringing her family in on the fun again, baby Phoenix and dad Carter wear mushroom cap hats.

  • Demi Lovato

    The “Cool For The Summer” singer dressed up as a sexy Snow White with a cleavage-showing dress. The Disney princess costume was made complete with an adorable apple purse. We love how the stars are going all-out for their costumes, making their accessories functional as well.

  • Kourtney Kardashian

    Kourtney has a great sense of humor when it comes to making fun of her sisters while honoring them at the same time. Kourt, who is due with her first child with Travis Barker soon, dressed up as Kim Kardashian when she was pregnant ten years ago at the Met Gala. Wearing the same exact high-neck floral gown with a thigh slit and matching heels, the Poosh founder also wore her hair in a long, center-parted ponytail. She hilariously captioned the post: “Freaky Friday.”

  • Halsey

    Halsey did her own hair and makeup, using her makeup line, about-face beauty. Cleverly using lyrics from her 2021 song, “The Lighthouse,” the singer captioned her post: “there is a lighthouse in the middle of the deep……” With a long red wig outfitted with seashells and charms, Halsey wore a mesh skirt with shells and a matching ruffly bra. Her boyfriend, actor and singer Avan Jogia, dressed up as a pirate/sailor to match her costume.

  • Megan Thee Stallion

    Hot Girl Meg never ceases to amaze us with her cosplay looks. This year, she showed up to “Hottieween” as the flower from Alice In Wonderland in the Tim Burton-themed party. On top of her elaborate, gorgeous head piece, Megan wore a mesh green bodysuit with ivies and leaves throughout. Among her photos shared to Instagram, there were Mad Hatters, rabbits, mad kings and queens galore.

  • Jessica Alba

    Paris Hilton isn’t the only star that wanted to dress up as the iconic Britney Spears. Alba wore a mesh glittering body suit and platinum blonde wig as another one of Brit’s iconic characters from her “Toxic” music video. Her friend and hairstylist, Brittney Conkle dressed up as Britney Spears from “Oops… I Did It Again” with the schoolgirl uniform and braided pigtails.

  • Lizzo 1

    Honoring the Mistress of the Dark, Elvira, Lizzo rocks a beehive hair-do as she looks at herself in a small handheld mirror. Wearing what looks to be a dress showing butt cleavage, fans flooded the comments section, writing things like, “I love Elvira and you, but girly, the cleavage is supposed to be on the other side.” Another fan hilariously commented, “Lizzo is cracking me up with this one [eyes emoji].”

  • Lizzo 2

    Lizzo is all about honoring the icons. This time, it’s Brazilian singer, dancer and actress, Carmen Miranda. Nicknamed “The Brazilian Bombshell,” she was known for her signature fruit hat outfit that she wore in her American films in the 1940s.

  • Keke Palmer

    The new mother is having fun with her Halloween costume this year, dressing up as the “Motha” of Dr. Frankenstein. She sets the bar high when it comes to her creativity and marketing and this video alone makes it hard to beat. In an adorable slideshow, her son Leo hovers over Keke on the table and she captioned the post: “He gave me LIFE.”

  • Drew Barrymore

    Happy little trees, Drew! The talk show host and actress went all-out with this very hairy Bob Ross costume, with chest hair, a graying goatee, eyebrows, and of course, Bob’s iconic afro. In her last slide, Barrymore takes a quick clip in which she raises the question: “How did I get here?”

  • Ed Sheeran

    The singer-songwriter really leaned in on his evil ginger-ness this year, dressing up as the horror doll, Chucky! His costume was so on point, fans commented on his post: “why didn’t you dress up this year?” One person wrote: “Okay, but why does this suit you so much [laughing emoji] [waving emoji].”

  • Elizabeth Gillies and Ariana Grande

    The former Victorious co-stars dressed up as Showgirls characters Nomi (Elizabeth Berkley) and Cristal (Gina Gershon). The two even recreated scenes from the 1995 drama in a three-part series on Instagram and showed off their acting chops.

  • Kim Kardashian and North West

    Ugh, as if Kim wouldn’t do an iconic Halloween look with North! The two dressed up as Cher and Dionne from 1995’s Clueless. Kim looked cute in her blonde wig and cute white shoes, but North is the one who stole the show. In every photo, the 10-year-old is giving so much emotion and sass. We love to see it.

  • Hailey and Justin Bieber

    The Biebers went waaay back in time for this prehistoric couple’s costume. The model sported a red wig and a latex costume for Pebbles Flinstone, while Justin went more the furry and felt route, completing his Bamm-Bamm Rubble look with some cringey feet slides.

  • Kourtney Kardashian and Travis Barker

    With their son Rocky Thirteen Barker due any minute now, the couple dressed up as iconic Beetlejuice characters Lydia Deetz and the titular character. The Blink-182 drummer looked really into his costume and it suited him really well, unsurprisingly.

  • Mariah Carey

    Dressing up as the sexiest character of all time, Carey has everyone’s attention from now until her holiday (Christmas) is here. However, she tells her fans in her caption: “#notyet” — something she has been telling people so they do not start focusing on Christmas too early. Her Jessica Rabbit costume looked fantastic on her, with a long red wig, sparkling strapless gown, and purple leather gloves.

  • Christina Aguilera

    As one powerhouse vocalist dressing up as another legendary powerhouse vocalist for Halloween, Aguilera did her thing dressing up as Cher from Burlesque this year! X-tina wrote in her caption: “On my favorite day of the year it’s only right to turn back time and tribute the OG trailblazer @cher. Cher’s message through her music and style has left a permanent mark on the world and to this day, I still can’t believe I had the opportunity to work with such a legend!!!! No one could ever fill the shoes of the great & powerful Cher. The love and respect I have for you is endless.”

  • Kendall and Kylie Jenner

    Pop Base on Twitter: "Kylie and Kendall Jenner dress up as Sugar and Spice for Halloween. pic.twitter.com/PMUHmqrJQ7 / Twitter"

    The Jenner sisters also took part in the matching costumes this year. The Millenials dressed up as Drew Barrymore and Debi Mazar’s characters Sugar & Spice from 1995’s Batman Forever. Their outfits, as usual, are completely spot on to the movie’s original.

  • The Rock

    Dwayne “The Rock” Johnson hilariously dressed up as David Beckham from his time playing for Manchester United. Wearing a highlighted, shoulder-length wig with a thin black headband, Johnson captioned his previous post: “265lb BLA-MOAN BECKHAM. #7 on the field. #1 in your heart.” Offering a definition for what “Bla-Moan” means, “The Rock” said it is “Black + Samoan” In one of his hashtags at the end, he points out he and Beckham share the same birthday, on May 2!

  • Lil Nas X

    Lil Nas X never disappoints when it comes to being really out there. This year, he dressed up as a sassy bloody tampon, complete with a very long white string that he carries around. In this hilarious video, the singer and rapper struts with white heeled boots and strikes pose after pose, almost tripping at the end.

  • Kim Kardashian

    For her solo costume, Kim K dressed up as Selma Hayek’s iconic character in 1996’s From Dusk Til Dawn, Santanico Pandemonium. She was the Vampire Queen of the Titty Twister and a former dhampir before being turned by her mother and grandmother. As people try to kill her, she turns them into her slaves and rules the bar by seducing humans before she feeds on them. It seems very fitting that Kardashian chose this character for Halloween.

  • Neil Patrick Harris and Family

    NPH does it again with his husband, David Burtka, and their twins Harper and Gideon, 13. Harris hilarious is old man Hades, the god of the underworld. Burtka strikes a strong pose as Poseidon, the god of the sea, carrying a trident and wearing shelled armor. Harper dressed as Aphrodite, the goddess of love, holding a dove in one hand. And Gideon is in two places at once, as Hermes, the messenger god, wearing winged sandals, a winged helmet, holding a winged staff.

  • Kerry Washington

    Washington sported a red, long-haired wig, extra-long nails, and some fake tattoos to dress up as superstar track and field sprinter, Sha’Carri Richardson. She posed exactly like Richardson in the slideshow, really getting into character. Using a play on their names, Washington writes in her caption: “It’s Sha’Kerry.” Sha’Carri loved the actress’ homage costume and posted a side-by-side on her Instagram Stories of the two.

  • Heidi Klum

    The “Halloween Queen” did it again this year, going above and beyond with her peacock costume. The model incorporated 10 Cirque du Soleil performers to make a stunning performance with acrobatics to make a giant peacock. Klum wore a prosthetic beak, fake feathers, and lots of Swarovski crystals.
