The great and the good of the showbiz world pull off spooktacular looks every year.
Stars from all walks of showbiz join in the fun and share their scariest or sexiest outfits to mark the occasion.
Famously Randy Gerber and Cindy Crawford transform their sprawling mansion into a Halloween ball for their celeb pals every year.
In the UK, Jonathan Ross also throws an annual Halloween extravaganza which every star wants an invite to.
Kim Kardashian and Kourtney Kardashian
The Kardashians always, always go big at Halloween.
Eeriest of all the years, Kim Kardashian and Kourtney Kardashian dressed up as ghosts from the showbiz past.
They rocked up to an A-list party with Kim dressed as Madonna and Kourt as Michael Jackson.
The pair got everyone talking when they turned up in identical outfits to what the late celebs wore to the 1991 Academy Awards.
Chrissy Teigen and John Legend
Chrissy Teigen and John Legend did a royally good job as posing as the Queen and Prince Phillip on Halloween.
In a statement blue coat and hat, the model waved to the camera in the same characteristic style of the Queen.
They both wore grey wigs to perfect their looks.
Hilariously the couple had planned to go out but they spent so much time getting ready, they were too tired afterall.
“We were gonna go somewhere, but we’re so tired,” Chrissy said at the time.
John told a different story as he admitted to fans they devoted so much time to dressing up for Instagram.
He said: “We just did it for the Gram.”
All eyes were on Harry Styles when he channelled Elton John in a sparkling Dodgers uniform.
Harry was the spitting image of Elton when he replicated the star’s famous look at the Dodger Stadium in Los Angeles in 1975.
And wow! It’s no wonder the Rocket Man hitmaker himself was impressed.
The singer took to Instagram to share photographs of Harry dressed in his iconic ensemble.
Every year Kylie Jenner looks sensational at Halloween.
But arguably it was dressing up as Disney’s Ariel last year which gave the Kardashian the wow factor.
The lip kit mogul morphed into the mermaid as she wore shells like a bra to cover her modesty.
Her naturally dark locks were covered by a vibrant red wig which cascaded down her shoulders to her petite waist.
Sexing up her look, the reality queen fashioned the mermaid’s green tail into a sequinned skirt with a soaring split to show off her legs.
She wrote next to the snaps: “Ariel grew up..”
Selling Sunset’s Chrishell Stause has already nailed her Halloween costume early this year.
The reality star was unrecognisable when she become Angelina Jolie ‘s villainous character Maleficent.
Her devilishly sexy attire ensured she had the spotlight on her during Dancing With The Stars’ Halloween special.
Spooky and sexy, Chrishell waltzed out in a plunging leotard with a cape sewn into the design and fishnet tights.
Her horns were worn as a dramatic headdress as one of the finishing touches to her terrifying look.
The bombshell added a slick of red lipstick for drama.
Khloe Kardashian and Tristan Thompson
Khloe Kardashian and Tristan Thompson fashioned themselves as Game Of Thrones ill-fated lovers Daenerys Targaryen and Khal Drogo.
Initially Daenerys (A.K.A Emilia Clarke) is forced into marrying Drogo (A.K.A Jason Momoa) but the unlikely duo fall in love.
However, their marriage is doomed as Khal dies and not even witchcraft can save the warlord from his fate.
Their love story is one of the most memorable in the Game Of Thrones saga so it’s no wonder the couple chose to pose as the fierce characters.
And wow did they do an astonishing job! Khloe and Tristan looked like they walked straight of the Game Of Thrones set.
Khloe styled an icy blonde wig to her waist, much like Emilia’s long flowing tresses in the epic series.
Her lover Tristan went to great lengths to look the part as he had the warlord’s tattoos painted on to his muscular chest.
Adele caused a stir when she dressed up as a glamorous clown for Halloween.
In 2017, the Hello hitmaker wore heavy eye make-up and a bold lipstick choice when she transformed on the spooky day.
The mother-of-one styled her blonde locks in a crimped style.
Her green dress featured quirky sleeves and embroidery of a Chinese dragon running along the hem.
She wrote: “Happy Early Halloween & Happy Birthday Gorgeous.”
