Craziest Celebrity Halloween Costumes

1. Jemima Khan as Melania Trump

(Image Source/ Hello Magazine)Jemima Khan has to win one of the craziest Halloween costumes of all time for her costume to The UNICEF UK Halloween Ball where she dressed up as Melania Trump. The stroke of genius and wicked humour comes from the doll version of Donald Trump clinging onto her in an inappropriate manner.

2. Heidi Klum as Shrek from Fiona

(Image Source/ Pinterest)This costume looks more like Fiona from Shrek than Fiona. We all love Shrek - and this costume is scarily accurate that it literally looks as though she's walked right out of the movie. Heidi Klum really killed this look, and the prosthetics are extremely impressive.

3. Iggy Azalea as Cruella De Vil

(Image Source/ modeljunkie)Now there's a clear winning part of this costume and we all know what it is... The fact that Iggy Azalea has committed to the character and the Halloween costume so much that she's literally accompanied by a Dalmatian - it makes this Halloween costume a clear winner in our eyes.

4. Heidi Klum as Jessica Rabbit

(Image Source/ modeljunkie)Heidi Klum pulls out all the stops when it comes to the craziest Halloween outfits. When she does a Halloween outfit, she does not do it by halves. In fact, she's totally in disguise. Again, the prosthetics are so realistic that she looks like a real-life cartoon Jessica Rabbit.

5. Rita Ora as Post Malone

(Image Source/ Hello Magazine)We love it when celebrities decide to dress up as one another. Rita Ora wore this crazy Halloween costume when she literally dressed up as Post Malone to the Kiss Haunted House Party 2018. This must've been a freaky moment when he saw his doppelganger walk in the room...

6. Katy Perry as a Cheeto

(Image Source/ Hello Magazine)This was Katy Perry when she attended a Los Angeles party in 2014. She came dressed as a Cheeto - bright orange, furry, and with a Cheeto handbag. Definitely not the scariest Halloween ever but definitely one of the most humorous. Plus, everyone loves Cheetos.

7. Emily Ratajkowski as Marge Simpson

(Image Source/ Hello Magazine)Model Emily Ratajkowski stole the show in a 2015 New York party which she attended when she appeared as Marge Simpson in the most iconic way, right down to the 30-inch high blue hair... She couldn't have more accurately portrayed the loveable Simpson character.

8. Cardi B as an evil nun

(Image Source/ Hello Magazine)Cardi B definitely had one of the craziest Halloween costumes when she attended a nightclub in Las Vegas as an evil but sexy nun. It was a controversial decision and didn't go down well with everyone. However, love it or hate it she's made it one of the craziest outfits.

9. Bella Hadid and Lydia Deetz as Beetlejuice

(Image Source/ Hello Magazine)Bella Hadid and The Weeknd in 2018 (back when they were dating) attended a Halloween party together as Lydia Deetz as Beetlejuice. We can appreciate the fact that these two have brought the spook factor which is after all what Halloween is all about.

10. Justin Timberlake as a Microphone

(Image Source/ The Sun)Justin Timberlake attended this Halloween party as a huge microphone. Which is a very apt outfit choice for a singer. The giant head gear which is what truly makes the outfit so great. Timberlake definitely earns points for originality as well as comedy value.

11. Kendall Jenner as Fembot

(Image Source/ Hello Magazine)Here is Kendall Jenner keeping it very glam (as usual), going as Fembot who is a robot from Austin Powers. It's definitely not a scary look...but it's extremely cute, pink and fluffy and definitely one we will be saving for this year's Halloween inspiration.

12. Chrissy Teigen and John Legend as Queen Elizabeth II and Prince Philip

(Image Source/ Pinterest)We love it when a couple co-ordinate their Halloween outfit. This outfit was from a few years ago when the late Queen and Prince Phillip were still alive. Chrissy Tiegan had perfected the beloved Queen Elizabeth's iconic bright matching outfit and John Legen looks great with a side parting...

13. Winnie Harlow as RuPaul

(Image Source/ gq)The stunning beauty imitated one of TV's favourites - Winnie Harlow as RuPaul - what a combination. This was back in 2018 in a Las Vegas club. And, if anyone can rock this look it is definitely her. This had to make the list of craziest Halloween outfits.

14. Harry Styles as Elton John

(Image Source/ Hello Magazine)As we know, Harry Styles is a huge fan of Elton John. This is at a Halloween party in Beverley Hills, California 2018. The two of them are now good friends, as well as occasionally working with one another. Which makes this Halloween costume even better the way Styles is paying tribute to his icon.

15. Steph Curry as Jigsaw

(Image Source/ gq)Thankfully, we still have some celebs going for the horror Halloween look. In 2018 Steph Curry went as Jigsaw, the Horror movie. He has totally pulled off the look of this creepy character and we would definitely run away if we saw this guy cycling towards us...

16. Kylie Jenner as Christina Aguilera

(Image Source/ modeljunkie)Kylie Jenner always looks good - but here she's managed to look better than ever replicating Christina Aguilera's look from her music video 'Dirty'. Instead of scaring people away with her crazy Halloween look Kylie Jenner probably had people ordering the outfit.

17. Fergie as a Toddlers and Tiaras contestant

(Image Source/ modeljunkie)This isn't creepy in the conventional horror way, but we have to say there is something creepy about an adult being dressed as a little kid. Fergie has totally pulled this look off and it is definitely one of the craziest Halloween looks and totally original. She looks like she's stepped right out of Toddlers and Tiaras.Carmen Electra and Matt LauerC.J. Parker, Pamela Anderson's character from Baywatch

18. Liv Tyler as a bun in the oven

(Image Source/ modeljunkie)We love this crazy Halloween costume choice. Liv Tyler used the opportunity of having a bun in the oven to go literally, as a bun in an oven. We've all heard this common phrase for a pregnant woman, and Liv Tyler decided to take the joke even further.

19. Nina Dobrev as Billie Eilish

(Image Source/ Pinterest)Nina Dobrev went to her Halloween party dressed up as Billie Eilish, the popular famous singer. It's always crazy seeing one celeb look like another. And she's got it bang on. The green roots, the clothes, the composure - it's as Billie Eilish as you can get without having the real thing.

20. Lupita Nyong'o as Dionne from Clueless

(Image Source/ Pinterest)Lupita Nyong'o is a famous actress and in 2018 she decided to go as Dionne from Clueless. Clueless is a 90s movie with the best and most iconic clothing, so she was onto a winner with this costume. Not only does she pull off Dionne's look, but she also manages to make it look like the height of fashion again.

21. Rihanna as the Teenage Mutant Ninja Turtles

(Image Source/ Pinterest)This is Rihanna and her girl gang back in 2014 when they attended a Halloween party as the Teenage Mutant Ninja Turtles. And while it's not entirely the most original outfit choice, have you ever seen such a more glamourous set of Teenage Ninja Turtles?

22. Bruce Willis & Stephen J. Eads as the Shining Twins

(Image Source/ Pinterest)Okay, this has to be one of the craziest Halloween we've ever seen. And we love it. Here is Bruce Willis and Stephen J. Eads as the shining twins. There is definitely something comically horrifying seeing these two grown men portray these two very scary little (or in this case big) twins.
