LOOK: Here's how Hollywood stars showed their fun, spook-tacular sides for Halloween 2023

Ed Sheeran as Chucky

O darling, you look perfect tonight. The British singer-songwriter dressed up as the demonic, serial killer doll Chucky from the Child’s Play horror franchise.

He wore bloodied overalls over a multicolored striped long-sleeved shirt. He also had a stitch and scar makeup on his face.

As for the hairstyle, Ed didn't need much effort as he already shares ginger hair with Chucky.

Justin and Hailey Bieber as The Flintstones

The celebrity power couple channeled their inner Pebbles and Bamm-Bamm from the iconic cartoon show The Flintstones.

Hailey wore a neon patent leather sleeveless crop top, complete with the crescent moon markings and tatters. She also rocked a coral micro miniskirt with blue and orange hues, as well as a bone detail on the waist.

Justin, meanwhile, went topless and sported furry yellow bottoms and a pair of foot shoes. He also had a yellow cap with irregular shapes.

Kendall Jenner as Marilyn Monroe

The socialite went back in time, becoming the blonde bombshell Marilyn Monroe.

Kendall donned a curly wig and had makeup that made her cheeks rosy and highlighted her lips for Halloween.

She also particularly rocked a black turtleneck with long sleeves, the actual dress Marilyn wore when she (in)famously sang a sultry happy birthday song to President John F. Kennedy.

She even wrote “happy birthday mister president” in the caption of her Instagram post.

Machine Gun Kelly and Megan Fox as The Bride and Gogo Yubari from Kill Bill

Peak kino? The pair assumed assassins The Bride and Gogo Yubari from the action thriller Kill Bill by Quentin Tarantino.

Machine Gun Kelly opted for a blood-stained yellow tracksuit, a pair of yellow sneakers, and wielded a katana.

Megan, meanwhile, wore a Japanese school uniform with an above-the-knee plaid skirt. She also sported bangs and wielded a meteor hammer.

Both of them also had blood makeup on their faces.

Adele as Morticia Addams

Hello from the other side? The award-winning English singer transformed into family matriarch Morticia Addams from The Addams Family horror franchise.

Adele had jet-black hair that matched her silk-black dress. She also had gothic makeup, golden rings, and claw-like nails with blood designs.

Paris Hilton as Britney Spears

Gods won’t go crazy, and stars won’t go blind for once with the media personality’s choice to channel the pop star, Britney Spears.

Paris specifically donned the blue flight attendant costume that Britney wore in the music video of her hit song Toxic.

“Icons support icons,” she wrote in the caption of her Instagram post, along with a crown emoji.

Demi Lovato as Snow White

The American singer just showed that she’s the fairest of them all with her Snow White costume.

Demi nailed the blue and red puff-sleeved dress, the red bow, as well as the yellow skirt. Her hair was as black as ebony, her lips as red as the rose, and her skin as white as snow.

She also gave it a sexy twist with a black corset top with gold ribbing.

“My favorite time of the year. Happy Halloween,” Demi wrote with ghost and pumpkin emojis.

Khloé Kardashian as Bratz

The youngest of the Kardashian sisters opted for a Bratz doll as her Halloween getup.

Khloé donned platinum waist-long hair and wore a plaid yellow mini dress with a long-sleeved white shirt underneath. She also sported a yellow beret and a handbag with the Bratz logo.

Heidi Klum as a peacock

The model and television just went peacock mode, literally and figuratively.

Heidi was almost unrecognizable in her avian costume, wearing a blue suit and a mask that covered her entire face except the eyes.

Nine individuals, meanwhile, flanked her as they served as her tail, feathers, and claws.
