Year after year, celebrities take Halloween costumes to the next level, enlisting their glam squads to conjure up some of the spookiest magic around. 2018 was no exception, as stars like Sofia Carson and Luis Fonsi played dress up for festive events or to take their kids trick-or-treating. Scroll through to see our compilation of all the most ghoulishly glamorous looks!

It was a milestone Halloween for these Swedish royals. For their first official All Hallows Eve since relocating to the United States, Princess Madeleine of Sweden and her little ones got festive! The 36-year-old royal took to Instagram to show off her and her three children's 2018 costumes. The family opted to go cute, instead of scary, with the princess donning a simple black cat look. She sweetly hold her 7-month-old Princess Adrienne in the picture, who made for a beyond cute pumpkin on her first Halloween.

Meanwhile, Princess Leonore, 4, and Prince Nicolas, 3, used face paint to become Batman and a colorful mermaid. “Happy Halloween,” Madeleine wrote along with the snap, which saw them posing in front of a haunted house decoration.

Queen of Halloween Heidi Klum did not disappoint with her highly-anticipated annual All Hallows' Eve look. Year after year, the America's Got Talent judge manages to top herself in the name of her big bash and for 2018 she underwent a shrekening. The model and her boyfriend Tom Kaulitz spent hours in the makeup chair to create the ogre-timate couple's costume: Princess Fiona and Shrek! The icing on their swampy cake were their accessories: a stroller with baby ogres and a fairy tale like onion buggy, which they rolled up in. 

The spooktacular was held at LAVO New York, which was transformed into an unBOOlievable Halloween haven with the help of Party City. Partygoers danced to the DJ set by Questlove while enjoying signature cocktails by SVEDKA Vodka, including: Muddy Brew, Swamp-tini, Mud Slide and Dark-N-Murky.

Another couple's costume that hit it out of the graveyard at Heidi's party was Bella Hadid and The Weeknd's Lydia and Beetlejuice. The pair honored the morbid wedding scene from Beetlejuice right down to the moldly makeup. Taking to Instagram to share more photos, Bella joked: "yelled beetlejuice 3 times and he appeared".

Winnie Harlow stepped off of the runway and into the drag race for Heidi's epic event, turning up as "the one and only" (she wrote on Instagram) RuPaul. 

Somebody stop me! Kat Graham took a page from Heidi's green-makeup book, undergoing her own fx transformation to become The Mask. The look seemed to give her an extra boost of energy, too, as she leapt into the air on the carpet. "Thank you Jim for being my forever inspiration," she wrote on Instagram about Jim Carrey along with a photo of her in costume.

"AS IF!" Lupita Nyong'o was clueless at Heidi Klum's 19th Annual Halloween Party. The Oscar-winning star exuded 90s style as she went as the film's character Dionne for the October 31 event. Lupita not only shared photos of her look on Instagram, but reposted one star who was inspired by one of her own on-screen roles! Scroll to see...

Adrienne Bailon, who dressed as a playful kitty, came out to celebrate Halloween at Nights of the Jack in Calabasas with her husband Israel Houghton.

"My Wakanda Knots have unraveled!" Lupita said, reacting to a video she reposted that shows Ciara dressed as her superhero alter-ego. The singer, her husband Russell Wilson and kids Sienna and Future went full out Black Panther for Halloween. "Wakanda #Family," Ciara wrote along with the festive foursome photo.

There were no royal engagements for Chrissy Teigen and John Legend on October 31st. The Hollywood couple, who chanelled top British royals Queen Elizabeth and Prince Philip for Halloween, were too exhausted to leave the house after getting all dressed up!

“We were going to go somewhere, but we’re so tired, so we’re at home,” Chrissy said in a relatble video on her Instagram Story. John hilariously added: “We worked all day…We just did it for the ‘Gram."

Speaking of royalty... Princess Beatrice of York threw on an eclectic mix of dazzling items for a unicorn-inspired look. Donning a purple wig and sparkly unicorn horn, Eugenie's sister stepped out for Annabel's Halloween Party 2018 at Annabels on October 31 in London, England.

Dangerous woman! Kourtney Kardashian totally nailed her Ariana Grande Halloween getup, hair extensions, short skirt and all! "God is a woman," she wrote on Instagram along with the stellar snap.

Make no moosetake, Oscar-winner George Clooney is said to be inside of that moose costume! The A-lister amoosed us all when he was spotted sneaking around L.A. in the head-to-toe getup, an easy way for the uber-famous actor to go incognito in the fall.

In his second costume for Halloween, George Clooney collaborated with his pals Rande Gerber and Cindy Crawford for a high-flying trio costume. The two men, who co-founded Casamigos together, were airline pilots while Cindy was a flight attendant at their Casamigos Halloween party at CATCH Las Vegas at ARIA Resort & Casino on Saturday, October 27.

Kendall Jenner got "randy" for the Casamigos Vegas bash, going all out in her Austin Powers fembot ensemble, along with two friends who were other characters from the groovy comedy franchise.

Meanwhile, Sophie rocked a comfy cozy elephant onesie! “Another Saturday Nite,” Joe captioned this photo.

In true Kardashian-Jenner style, Kylie documented the evening in her Instagram Story for all to see, flaunting the gathering's spooky decorations and day-of-the-dead decorated food. It looks like Kylie‘s attending friends got the memo and wore the same skeleton onesies as well!

They coordinated with their children to dress as rockstars. Supermodel Cindy donned a blonde wig and yellow shirt-dress as Blondie singer Debbie Harry, while Rande got glam as David Bowie's alter-ego Ziggy Stardust in a red wig and some legendary lightning bolt face paint. Seen here: the duo wigged out with actress Jane Seymour.

Cindy and Rande's kids looked equally rad and almost unrecognizable. The most transformed was Kaia Gerber who was a deadringer for Joan Jett in her black wig and getup. It was harder to pin down which rocker her brother Presley was, as he put on a Dark Seas Division shirt, bandana, scarf belt and rosary beads.

Paris Hilton went back to the 90s for the Casamigos party, dressing as a fabulous Furby!

Zoë Kravitz got creative for her Casamigos look. The Big Little Lies star dressed as a... literal nightime vampire? "Rise n dine. ( night time is morning for da vamps )," she elaborated on her Instagram, making her robe and mug take on a vampire more grounded.

Another costume that made you think was Nina Dobev. Despite her "campaigning for best picture sign," her collection of pieces was not too obvious. The only fitting explanation, amongst her baby items and microphone, that seems to fit is that she is the representation of the hit film A Star Is Born's Oscar campaign? Let us know if we got it, Nina!

Olivia Munn was more on the nose at the event, dressing up as one of the most popular supporting characters to come out of cinema so far this year: Peik Lin from Crazy Rich Asians. Olivia, herself, is half-Chinese and certainly fit the bill for Awkwafina's hilarious role.

A little birdy told us that Lauren Conrad and her son Liam coordinated with their cute costumes. The fashionista shared a glimpse on Instagram, writing: "I hope this little blackbird grows to <3 this holiday as much as I do!"

She elaborated on her website, writing: "This year I wanted to depart from the cutesy costumes of Halloweens past and step into something a little more… spooky. Inspired the classic horror flick, I channeled my inner Hitchcock character and created my best Melanie Daniels from The Birds. As seen on the movie poster, my costume depicts the famous bird attack that leaves Ms. Daniels terrified and full of bird scratches. I even bribed a little birdie to stand in as my sidekick!"

"But... what happened here???" Luis Fonsi questioned in Spanish along with this funny Instagram photo of him and his wife Águeda López in Disney World.

Sister, sister! It was 'just a bunch of hocus pocus' for Sofia Carson and Dove Cameron who channeled the Sanderson Sisters for their magical I Put A Spell On You performance at the Hocus Pocus 25th anniversary reunion TV special on Freeform. Jordin Sparks completed their sinister trio!
