Best celebrity Halloween costumes 2018 🎃

Perrie is totally unrecognisable in her Ursula the Sea Witch costume. She posted a video of herself doing an Ursula impression and we were instantly transported back to being terrified while watching The Little Mermaid. Those poor unfortunate souuuuls!

Good Morning may be celebrating 30 years on television, but presenter Holly Willoughby never fails to surprise us with her amazing style.

Holly paired her white fluffy ensemble with a silver glitter horn and a bushy rainbow coloured tail. This is a unicorn with some serious sass.

Ah, loved up newly-weds, Olivia and Alex looking… frightening. The Love Island duo swapped wedding whites for gory makeup last Halloween.

No Halloween costume is complete without a candelabra in hand as the GC demonstrates in this candid spooky snap – but keep those candles away from your hairspray next time, Gemma.

Gemma Collins gives us a close up of her glam make-up, consisting of a daring red lip, gold glitter and Halloween-style contouring.

Matching her cute cheerleader outfit with scary white contact lenses, Marnie is one team-mate we wouldn't want to bump into.

Inspired by Mexican holiday Day of the Dead Marnie Simpson dons skeletal makeup and red roses in this halloween costume.

It looks like Holly Willoughby isn't the only fan of unicorn dress-up, as Loose Women panelist Stacey Soloman shared a similar mystical look last year.

Pals Ferne McCann and Billie Faiers shared this Halloween selfie in 2017, showing fans their puurr-fect makeup. Will Sam Faiers put her feud with Ferne to the side, and join the besties this year?

Ferne's complete look consisted of spooky makeup and a simple black off-the-shoulder dress. This year will mark Ferne's first Halloween with her daughter, Sunday.

Sister-act, Kim and Kourtney dressed up as pop legends Michael Jackson and Madonna circa 1991 for last year's Halloween makeover.

Is there anything Kim Kardashian can't do? If she's not donning Madonna's glamour, she's mirroring the beautiful CHER – oh, and Jonathan looks great as Sonny, too.

Ex-Love Island and CBB star Gabby Allen looks so glamorous in her glitzy hat, perfect makeup and black, skull jacket.

TV presenter Emma Willis shows fans her funny side, as she dresses up with husband, Matt Willis. The pair transformed themselves into 'Deadward' for Halloween 2017.

Lydia Bright whips up a storm in her latex and lace outfit. Donning a long auburn wig and black lipstick, Lydia shows her dark side in this sultry snap.

Gigi Hadid had a playful Halloween last year. Swapping her usual chic look for a thick blonde wig and shiny leggings, the U.S celeb even danced around with Spiderman.

Ellie Goulding, is that you? The popstar worked 9-5 on this outfit, and the effort has paid off. We hope to hear a Dolly Parton inspired album to match her 2017 costume.

Rita opted for a classic halloween costume in 2014 - the one and only Barbie. Donning a bright pink outfit and matching pink tiara, Rita pulled off the girly look.

Swapping judging panels and yoghurt adverts for a night dressed as Cleopatra, Nicole Scherzinger looks seriously glam in her pic shared with fans last year.

Laura Whitmore and Alexandra Maurer prove they're not totally clueless when it comes to fancy dress. The celebs mixed 90s fashion with blood and gore for this Halloween look.
