Treat or Trick! The craziest celebrity Halloween costumes ever seen

The most outrageous celebrity Halloween costumes of all time are hard to beat — but that won’t stop these stars from continuously pushing the envelope.

Not to be outdone is Katy Perry, whose past getups include a Flamin’ Hot Cheeto, a mic drop and Hillary Clinton. Her unwavering commitment to the holiday has made her one to watch every October 31st — and that’s by design.

“For Halloween, I definitely have a very topical costume,” the “Teenage Dream” singer said in October 2021. “I like to hit the summary of the year on the head, and it’s very goofy as I go … I always tend to lean weird.”

Of course, it’s Heidi Klum who always understands the assignment. At her yearly bash, which has a strict “no costume, no entry policy,” the model consistently offers up fascinating fits that have ranged from grannies to apes to aliens.

“What I love the most [about Halloween] is for people to be able to escape and to transform into someone else,” the Project Runway alum told Vogue in 2020. “With makeup and a costume, you can be anyone and anything. That allows most people to be loose and have more fun.”

Megan Thee Stallion

The rapper ushered in Hot Girl Halloween with her 2021 costume, which paid homage to the 1987 horror movie Hellraiser and RuPaul’s Drag Race season 13 contestant Gottmik. 

Seth Green

The Austin Powers actor and his wife, Clare Grant, went as Chucky and his bride in 2021.

Heidi Klum

The model transformed into a wall and a bedsheet in a mini horror movie starring her husband, Tom Kaulitz, and her four children Leni, Henry, Johan and Lou. “Halloween is different this year, but that shouldn’t stop us from getting creative at home. Be safe, be spooky, and spend time with family,” the supermodel captioned an Instagram post on October 31, 2020.

Neil Patrick Harris and David Burkta

The couple could solve any crime by dinnertime in their 2019 couple’s costume of Mary-Kate and Ashley Olsen.

Joe Jonas and Sophie Turner

The pair was both creepy and kooky in their Addams Family costumes. “Happy Halloween from Morticia and Gomez Addams,” the Game of Thrones alum wrote via Instagram in 2018.

Tracee Ellis Ross

The Blackish star gave Lupita Nyong’o a chilling shoutout in this spot-on rendition of Red from Jordan Peele’s 2019 horror flick, Us. “This is horrifying,” commented fellow actress Issa Rae.

Halsey

The “Bad at Love” singer put together a very good Corpse Bride costume in 2020.

LeBron James

Is James the GOAT of Halloween? The NBA superstar channeled Johnny Depp in a razor-sharp “LeDward Scissorhands” costume.

Demi Lovato

You’ll float too. Lovato followed her complex Marie Antionette costume with this outrageously scary Pennywise outfit on October 26. The songstress teamed up with her mom, Dianna De La Garza, to recreate characters from the iconic Stephen King novel.

Kevin Hart

The stand-up comedian perfectly channeled his Central Intelligence costar’s hilarious throwback photo — gold chain and all.

Jessica Biel

“It’s Gonna Be Me.” Biel trolled husband Justin Timberlake by reliving his ‘NSync glory days at the annual Casamigos Halloween party in Beverly Hills. JT joined in on the fun as a giant microphone.

Beyoncé, Jay-Z and Blue Ivy

Life in plastic! The couple dressed as Barbie and Ken in 2016, with their oldest daughter also dressed as a doll. The rapper was encased in a box with the words “Black Collector Edition” and “40th Anniversary Ken” written on it.

Dakota Johnson

The 50 Shades of Grey star embodied a sexual innuendo in 2015, holding a blow dryer and dressing as the late Steve Jobs to be a “blow job.”

Chrissy Teigen

The model and cooking enthusiast hilariously channeled Food Network host Guy Fieri in 2015 by wearing his signature platinum hair, goatee, sunglasses and flame-themed button-down.

Ellen DeGeneres

The talk-show host was so amused by Nicki Minaj’s revealing outfit during a September 2013 appearance on her show that she decided to wear an exaggerated version of the musician as a Halloween costume the same year. “This year I decided to go as something really scary … half-naked,” DeGeneres joked at the time. “Of course, I’m Nicki Minaj. Nicki was on the show a few weeks ago and her shirt was not … she took our show from PG to double D, that’s what she did!”

Heidi Klum

The model was unrecognizable as an old woman in 2013, wearing ultra-realistic age spots on her body and raised varicose veins running up her legs. To complete the look, Klum donned a white wig.

Iggy Azalea

If she doesn’t scare you no evil thing will! Beyond Cruella de Vil’s famous split-color wig and black and white duds, the rapper committed to the role in 2013 by bringing a real-life Dalmatian out with her.

Jessica Alba

Sixteen months after welcoming daughter Honor, Alba got into character in 2009 as Dora the Explorer, and husband Cash Warren dressed as Dora’s cousin Diego.

Heidi Klum

In 2015, Klum wore giant prosthetic breasts, a huge butt and fake eyelids to step out as Jessica Rabbit.

Julianne Hough

Hough apologized after receiving backlash for wearing blackface as part of her 2013 costume: Orange Is the New Black’s Crazy Eyes (played by Uzo Aduba).  “I am a huge fan of the show Orange Is the New Black, actress Uzo Aduba, and the character she has created,” she said in her apology at the time. “It certainly was never my intention to be disrespectful or demeaning to anyone in any way. I realize my costume hurt and offended people and I truly apologize.”

Justin Timberlake, Jessica Biel and Silas

The couple and their then-18-month-old son went as characters from Timberlake’s animated film Trolls in 2016. “When you make your whole family dress up as the characters from the movie you’re in but your wife secretly loves it and your son won’t keep his troll wig on,” the singer joked in an Instagram post. “Shoutout to @jessicabiel #2BranchsandaPoppy #Trolls #didIuseaholidayforselfpromo Happy Halloween, everybody!!!!”

Katy Perry

In 2016, Perry went all out to get into character as Hillary Clinton, including a cropped blonde wig, prosthetics to change her face shape and a more demure wardrobe. CAA agent Michael Kives dressed as Bill Clinton for much of the night.

Kylie Jenner

The reality star dressed up as “Dirrty”-era Christina Aguilera in 2016, donning a tiny black-and-yellow bikini top, thigh-high black boots and black-and-yellow pants that showed off a peek of her bum as a tribute. Aguilera complimented the look and invited Jenner to wear the costume two months later at the singer’s birthday party.

Katy Perry

The singer wore a full-body microphone costume and laid on the floor to be a “mic drop” in 2015.

Liv Tyler

Pregnant with daughter Lula Rose, Tyler went as a “bun in the oven” in 2014.

Melissa McCarthy

The actress went incognito in 2013 as a bearded fisherman while trick-or-treating with daughters Vivian and Georgette.

Sofia Vergara

The Modern Family star wore a full Angry Birds suit in 2011.

Miley Cyrus

In 2013, the singer channeled Lil’ Kim circa the 1999 MTV Video Music Awards, wearing the rapper’s now infamous purple wig and a skintight sequined purple jumpsuit that completely exposed her right breast. Her nipple was concealed only by a purple, bedazzled pastie.

Orlando Bloom

In contrast to then-girlfriend Katy Perry’s Hillary Clinton costume, Bloom dressed as an exaggerated Donald Trump in 2016, wearing a large bright red wig, a red “Make America Great Again” baseball cap and cartoonish hands and a mask in a clear nod to the president.
