Never to be left out of a Halloween bash, Kourtney Kardashian donned a costume that recalls an iconic outlaw. There’s also a look at Taylor Swift taking flight and that time that Farrah Abraham believed she was a royal.

Boo! Get ready to drop that jaw as the 59 most over-the-top celebrity Halloween costumes come to life... with quite a few who look like death!

Boo, indeed! Dancing with the Stars veteran Cheryl Burke went for a gothically ghostly look for her visit to Lambert’s Ghost Town Halloween fete.

Tara Reid usually dons something sexy, skimpy, devilish or some combination of all three for her celebrity Halloween costume. This time out, it is hard to pinpoint exactly what the Sharknado actress was going for, but she seemed to be having fun and in the end, isn’t that what Halloween is all about?

Sarah Hyland of Modern Family fame has nailed the look of Alice from the Resident Evil movies. She’s so believable as the heroine from that franchise that many at the Just Jared Halloween bash might have been looking for zombies lurking around the corner!

What does the wife of a tequila maker who throws an annual Halloween bash wear to the big event? If you’re Cindy Crawford, you can do whatever you want at husband Rande Gerber’s ghoulish gala. Got to give her props for doing the rocker chic justice, from the jet-black wig on down to the above-the-knee, leather, high-heeled boots.

Paris Hilton has been making legendary appearances on many a best celebrity Halloween costumes list. What can be said? The girl likes to dress up. Now, when it comes to this particular get-up, we’re not sure what she is going for… but it works. Is it a sexy cat? Is she a sexy, but somewhat psycho-looking, bunny? Sometimes costumes don’t need explanations and that is certainly the case for Paris with this costume.

The Real Housewives of Orange County star Gretchen Rossi nailed her addition to the celebrity Halloween costumes lexicon at a Life & Style Weekly’s Eye Candy soiree. Talk about paying attention to detail! The fur matches from the neckline through the wrists, all the way to the boots. The Scandinavian-themed outfit fit the moniker for the party itself… eye candy.

Everyone knows that LeAnn Rimes can sing like an angel. On this particular Halloween, the country singer turned pop princess got to get all dolled up as an angel—albeit a “sexy” one.

D'oh! One can almost hear supermodel and sometimes actress Emily Ratajkowski saying, “Oh, Homie,” as she channeled The Simpsons matriarch, Marge. Makes you wonder how that sky-high blue wig fared over the course of the evening—Ratajkowski could easily have run into a few ceilings with that puppy!

Kendra Wilkinson has all sorts of history at the Playboy mansion. For starters, she famously lived there as a member of the trio that delightfully invaded our homes in The Girls Next Door. In what would be one of the last Halloween bashes at the famous mansion, Wilkinson visited her ex, Hugh Hefner, and got all decked out as a sexy skeleton with impeccable taste for hair hue.

It is doubtful that one of the biggest flops in movie history, Cleopatra, will ever get the remake treatment. There has been talk (after all, this is Hollywood and they remake everything) that Angelina Jolie would be perfect for the role. For your consideration, presenting Pussycat Dolls leader Nicole Scherzinger as Cleo for the Jonathan Ross Halloween party. Is she not dazzling or what?

Sometimes a great Halloween costume does not even have to be about what you are wearing. That was certainly the case with Fast And The Furious star Jordana Brewster. Her Halloween look was all about the face makeup and hairstyling. Her Día de los Muertos manifestation is magnificent.

Looks like dating country superstar Blake Shelton has rubbed off on the former leader of a ska-rock band. Gwen Stefani looked quite the cowgirl for her contribution to the best celebrity Halloween costumes.

Kourtney and then-beau Younes Bendjima (the two split) made the scene as an iconic couple, Bonnie and Clyde. History has shown (and a stellar movie starring Warren Beatty and Faye Dunaway) that things didn’t end so well for Bonnie and Clyde. The same could be said for Kourtney and Younes. Although their demise certainly didn’t involve being bullet-ridden!

Although they are no longer together, Pauly D and Aubrey O’Day can always cling to the memories of their extraordinary Halloween couples costume efforts. The Jersey Shore star and pop star went for a fun, medieval look that seemed to channel magic and mystery. Miss them as a couple? You can always see them in clips from Marriage Boot Camp: Reality Stars!

Longtime Heidi friend Zac Posen is a legend in crafting designs that are astounding on many levels. Zac showed up for his friend’s annual Halloween bash in the most hauntingly awesome ways with this spooky sensation of a costume. Honestly, his look gives off the feel of something out of The Walking Dead. That’s high praise.

One thing that is obvious from this costume from American Idol veteran Katherine McPhee is that she is a disheveled housewife. Many celebrities go for all-out glamour or drop-dead sexiness when it comes to their costume choice for Halloween. Got to give Katherine props for going the other direction. When it comes to Halloween costumes, a good look is a good look and she has got the look.

Maroon 5 bandmates James Valentine and Adam Levine appeared to be having a ball dressed as women for a party that would find them taking the stage in those costumes and performing their hits. The Casamigos Halloween Party has to be saluted for its choice of bands—who will be playing the Super Bowl Halftime Show in 2019. And is it wrong to think that Adam fills out that leopard-print bustier quite well?

What a trio of celebrity Halloween costumes! That’s then-couple Jennifer Lopez and Casper Smart, along with Nicole, giving off their best haunted Halloween look at one of Heidi's legendary Halloween soirees. Notice the attention to detail on all of them, but particularly the ice-blue contacts that J-Lo sported!

You have to love when one of the best celebrity Halloween costumes requires a bit of thought on the part of those witnessing the glorious get-up. That is certainly the case with what Lucy Hale wore for this All Hallows’ Eve bash. The former Pretty Little Liars (could there be a reunion soon?) star was the official logo for the social media site Twitter! Props to the blue hair, big-circled glasses and, of course, the hashtag-adorned skirt. Very clever, indeed.

Couple’s costumes are the best, and few have nailed it as well as the pair that met on the set of the hit film, Pitch Perfect. Skylar Astin and Anna Camp have fans shouting, “We’re not worthy! We’re not worthy!” with their stunning look as Wayne and Garth from Wayne’s World.

Modern Family star Ariel Winter went for a bare-bones costume when she headed out for the annual Just Jared Halloween soiree. Get it?! Slowly, but surely, Ariel has been trying to shed that child star image that the world has become accustomed to from her. With outfits like this one, the actress certainly shredded all memory of her being a “kid” star and has firmly moved into the world seeing her as an adult.

The Stranger Things star donned an outfit that is quite popular among celebrity Halloween costumes. It would be easy to see Joe Keery in a Harry Potter movie. The big question is—which house would you put him in? From the outside, it appears that prophetic hat would put him in Gryffindor!

Dancing with the Stars pros are accustomed to being in costume all the time—it’s their job! So, instead of going for a Halloween costume that required a lot of work, or was an enormous challenge to enjoy one’s evening out, who could blame Derek Hough for showing up for a holiday bash as a fuzzy bear?

Giddy-up! The Boy Next Door and Step Up veteran had a blast as a cowboy for the Maxim magazine Halloween party. Ryan Guzman and his contribution to the celebrity Halloween costumes landscape had great attention to detail. Look at the stitching on that blazer! Well done, sir. Well done.

Joe Jonas got into the Olympic spirit with his Halloween costume. Not sure what sport that outfit befits, but it is colorful, attention-grabbing and one not easily forgotten, thus why it is on our list of the best celebrity Halloween costumes!

Jessica Alba and her friend have to be saluted for their uncanny looks that can only be achieved when two friends coordinate something fabulous. Jessica and her pal are impeccable as the devilishly delightful duo from the hit show Absolutely Fabulous… bottle included!

No one has looked happier to be the devil than Alessandra Ambrosio did as she hosted her own Heaven and Hell party.

Reality TV star Farrah Abraham is a royal something with this Halloween costume that must have thrilled her young daughter. After all, most little girls do adore their princesses!

Nicki Minaj has been a fairy godmother for 37 of her fans, paying for their college tuition in the most altruistic of moves. Given that fact, her Halloween costume for her appearance at 1 OAK Nightclub in Vegas was beautifully apt. Wonder how many wishes she granted with that glorious wand?

The Force is strong with this one! Nicole “Snooki” Polizzi, her husband Jionni Lavalle and their adorable two kids channeled the galaxy far, far away for their Halloween costumes with Snooki nailing the Princess Leia look—right on down to the Cinnabon-on-the-ears hairstyle.

The couple costume opportunities are many when two lovebirds decide to go that route at Halloween. Channing Tatum and Jenna Dewan may be dating other people, but when they were still married, they showed up at a George Clooney and Rande Gerber Halloween bash as one of Dr. Seuss’ most popular creations—the one and only Cat in the Hat. But wait, isn’t the point of the couples’ costume to arrive at a fete as a duo, such as Ron Burgundy and Veronica Corningstone from Anchorman or Sonny and Cher? Not necessarily as the same character!

When Hugh Grant showed up to a UNICEF Halloween party, his costume raised more questions than answers. Like, is he a lion? A donkey? He’s definitely some sort of animal. It’s brown. Does it roar or like to be known as an ass? Regardless of what it is, there is something truly extraordinary about this costume and that is witnessing the highest brow of English actors not only appearing in a “what on earth is he wearing?” costume but looking so disheveled! See, got to love this holiday… you can literally let it all hang out and no one bats an eye. It’s Halloween, after all!

How awesome does Josh Duhamel look as legendary fashion designer Karl Lagerfeld? What’s truly fascinating about this photo of the now former couple is how Fergie is all dolled up as a sexy white kitty...clearly Lagerfeld's famous cat, Choupette. Look closely. See the “CC” gloves and megaphone? Those stand for Coco Chanel, obvs!

John Stamos and his wife, Nicky Weylan, got totally into the Halloween spirit with their costumes. Although the pair did not go with a couples costume, they did own their respective routes with John going for devilish(ly handsome) and Nicky opting for the out-of-this-world alien.

"Rock n' roll!" For those of you who don’t know, that is the most memorable quote from the character that Chelsea Kane dressed up as for Halloween. That is none other than Mary Katherine Gallagher (famously created by SNL legend Molly Shannon).

Christina Milian went to the Carlton Halloween Nightmare party in a skin-tight cheetah costume that she matched with killer black boots. So sure that in the jungles of Africa, those boots would come in handy for the world’s fastest animal.

Melissa Bolona went the cavewoman route for her visit to a Halloween fete hosted by Adam Lambert. Perhaps the actress and model found a friendly caveman inside the fete? Bonus to know that they had high-heeled boots back in those primitive days of early humans!

Kate Hudson had to be seriously patient for the makeup artist who had her brilliantly costumed as a Day of the Dead reveler. The attention to detail on her face, seen heading into the Casamigos Annual Halloween Party, is stunning. Often, Halloween costumes can be works of art. Kate's get-up can easily be classified as such.

Singer Charli XCX was downright devilish as the host of hell. Love her commitment, head to toe… even her shoes are red.

Merely weeks after Miley Cyrus famously grinded against Robin Thicke at the MTV VMAs, Perez Hilton chose to go as Miley for Heidi's Halloween bash. The gossip columnist utterly nailed not only the look itself, but the attitude and Miley swagger. Right on down to the twisted tongue!

Long before she overdosed on heroin, Demi Lovato was zombie-rific with her addition to the best celebrity Halloween costumes. Imagining exiting the bathroom, or simply entering a room, at this bash and running face-to-face with this monstrous look from the singer? Scary stuff!

One can never go wrong channeling one of Hollywood’s greatest icons. That is exactly what Bethenny Frankel did with her Marilyn Monroe Gentlemen Prefer Blondes costume. Diamonds really are a girl’s best friend.

Comedian Jerry Seinfeld made a curious choice for his celebrity Halloween costumes contribution. Attending a Culver City Studios bash, with wife Jessica Seinfeld, the Seinfeld creator/star showed up as a solar race car driver? Mrs. Seinfeld did a great job with her diner waitress costume. Love the name, Sugar, and the nice touch with the pit stains!

Broadway star Cynthia Erivo was beyond committed to her Halloween costume for Heidi's bash. The actress, who crossed over to the big screen opposite Chris Hemsworth and Jon Hamm in Bad Times At The Hotel Royale, found silver screen inspiration with this look obviously taken from James Cameron’s legendary Avatar. Would not want to clean out her tub after the party… there’s going to be a whole lot of blue body paint circling that drain!

Given how the marriage of La La Anthony and Carmelo Anthony fell apart with allegations of cheating, it would be easy to see how the former Mrs. Anthony would be ready for a fight. Her costume for a Halloween party she hosted screams, “Don’t mess with me!” This is one badass ninja, right on down to the thigh-high leather black boots!

Great celebrity Halloween costumes do not always have to be a head-to-toe effort. Sometimes an intricate hairstyle or magnificent makeup job is all one needs to hit it out of the park. That was the case with Sarah Michelle Gellar and her bedazzled hair and fabulous face paint.

Musician French Montana appears to be channeling icon Hugh Hefner—or maybe he’s just a sailing captain in a comfortable robe smoking a pipe! Beside him is something that should be celebrated, someone taking a superhero and switching the genders on us! Angela Simmons slays as Captain America. Bet she’d take down a legion of Nazis as well, if not better, than Chris Evans did in his debut as the Marvel character.

Glad to see that Coco Austin is taking her studies seriously. The wife of Ice-T looks like she is more ready for sexy time than study time with her choice of celebrity Halloween costumes.

What on earth is Heidi Klum for Halloween on this year? This is one seriously out-of-this-world costume. As The Roots leader, Questlove, has a blast by her side, Heidi's get-up has to be an alien insect of some sort. Anyone else have any other ideas?!
