The Real Housewives of New York star Kelly Bensimon got real with her bouncing bunny Halloween costume at Klum’s bash.

Poison Ivy is always a popular choice for Halloween costumes, and if anyone pulled it off, it was songstress Rita Ora.

Irish pop star Ed Sheeran was pretty in pink as a pimp at Jonathan Ross’ annual Halloween bash in London.

Not sure what Modern Family star Ariel Winter was trying to be with her Just Jared Halloween party appearance. Was she channeling a sexy nurse who had the unfortunate experience of running into a zombie? Either way, it worked.

Hail to the Chief(s)! The then-couple (are Orlando Bloom and Katy Perry back on?) made quite an appearance at Kate Hudson’s annual Halloween bash. The pop culture power couple scored big-time as the political power couple of the day, Bill and Hillary Clinton. Nice touch… the “I’m with Her” pin that Bloom donned that was the icing on this costume cake of excellence.

Kelly Ripa utterly nailed the look and demeanor of DC Comics’ Harley Quinn before her morning show. Wouldn’t want to mess with her on any evening, but especially as the bat-wielding Batman villain.

“I Got You Babe,” indeed. Kim Kardashian, a Halloween costume legend, dressed relatively conservative on this particular October 31 as Cher. Her longtime BFF, Jonathan Cheban, morphed into Sonny Bono. If there was karaoke at the George Clooney and Rande Gerber hosted event, they would have slayed it!

Another best celebrity Halloween costumes stalwart is Paris Hilton. The hotel heiress did the pretty princess thing in an outfit that recalled Jasmine from Aladdin. Then again, that might be too wholesome for the sex tape veteran—perhaps she is just trying to be a sexy Arabian princess!

Vampire bride? Perhaps. The thing is Kourtney Kardashian was missing something quite important—fangs! Kardashian was probably doing the sexy bride with blood running down her face thing. Everything doesn’t have to be all about vampires, after all… Twilight was 10 years ago now!

Who doesn’t love it when a couple does the Halloween coordination costume thing? Making it work as the leaders of the Mouse House are Jenny McCarthy and her husband, Donnie Wahlberg, as Mickey and Minnie Mouse.

Carmen Electra was tapped to host the Foxwoods Resort Casino Halloween bash and decided to show up doing what made her famous. She did the sultry celebrity Halloween costumes thing. One question… how much do you think her feet hurt in those 10-inch heels?!

Ellie Goulding was clearly hoping that people would ask her to belt out “I Will Always Love You” on this particular Halloween. Her costume as Dolly Parton was pitch perfect and she certainly possesses the pipes to pull off the iconic Parton track!

Someone who relishes in the magnificence that is celebrity Halloween costumes is Ice-T’s better half, Coco Austin. She probably started a slew more fires than she put out in this sexy firefighter getup. Nobody should be shocked anymore by what she does, after all Austin took out her baby daughter in a barely-there bikini!

Clearly, Heather Graham saw Disney’s Coco and decided to mark the Mexican Día de los Muertos with this difficult-to-pull-off combination of costume and makeup. She got a “10” for effort and presentation.

Gabrielle Union would certainly stop traffic with one of the more sizzling celebrity Halloween costumes at Klum’s 17th annual event.

Who do you think Tyson Beckford was trying to be with this costume? Deadpool, perhaps? Doesn’t really matter. He clearly was having a blast letting loose at the Freak Show Halloween Party.

Although Pauly D and Aubrey O’Day broke up, they will always have their killer turns coordinating costumes on Halloween. Hail, Caesar, indeed! For fans of the couple, one can always watch them fight on Marriage Boot Camp: Reality Stars.

A popular costume for couples every year is Sonny and Cher. Power pair Cindy Crawford and her husband, Rande Gerber, looked downright groovy, baby!

Michelle Trachtenberg dazzled in her Day of the Dead costume for the Just Jared Halloween bash. How long do you think this getup took to put together?

Hitting the high notes on the cute meter was The Real Housewives of New Jersey break-out star, Melissa Gorga and her family. Her Dorothy from The Wizard of Oz keenly knew that she is not in Kansas anymore… this is Jersey, baby! Funny note from this celebrity Halloween costumes shot… her Toto did not look so thrilled to be walking the boulevard, no? Maybe the pup is just camera shy?

Hey, if Johnny Depp ever tires of portraying the Mad Hatter in those Disney Alice in Wonderland movies, they should give Gerard Butler a call!

Property Brothers stars Jonathan Scott and Drew Scott battled it out one Halloween. Their fight? That's easy... it was to determine who gets the title of loving Wonder Woman more. Who do you think won?

In the category of people no one ever thought we’d see in the same photo is Bette Midler and Dita Von Teese. But, they do look divine at Midler’s annual Halloween event in New York City.

All that is missing from the “It” singing star of the moment’s costume is 101 Dalmatians. Cardi B slays as the iconic Disney villain, Cruella de Vil.

Mariah Carey appeared ready to belt out “Double, double, toil and trouble” as a witch. Clearly, the singing sensation was the hostess with the most-est.

Who is that in the most impressive of celebrity Halloween costumes? Seriously, when you see who it us, you will marvel at the mastery that went into creating this look. Under all that makeup and Princess Fiona costume is... Arrow and Teen Wolf star Colton Haynes!

Leslie Mann and her husband, Judd Apatow, appeared ready to party as they walked up to the annual Halloween bash thrown by Kate Hudson at her Los Angeles home. With that helmet tucked underneath her arm, one would not want to mess with Mann in that roller derby costume!

Alessandra Ambrosio was downright heavenly as an angel/unicorn at her own Halloween bash. What does everyone think she was going for... angel? Unicorn? Something else entirely?!

Pink leather skin-tight skirt... check! Long-locks blonde wig... check! Bethenny Frankel brought her Halloween costume A-game with this dazzling get-up. Even love the matching pink furry coat!

The veteran of several The Bachelor shows, Corinne Olympios certainly read the room well with her costume for the Maxim Halloween Party.

That is some serious dancing talent, all in one photo! Dancing With The Stars pros Peta Murgatroyd, Maksim Chmerkovskiy, Jenna Johnson and Valentin Chmerkovskiy seriously spooked party-goers with their Fab Four of celebrity Halloween costumes.

One must salute Maria Menounos with her military costume at the Casamigos Tequila Halloween Party. “The Yanks Are Coming!”

Victoria Justice seems to be channeling Beetlejuice, but she seemed to have stopped after the prison-stripped blazer and pants. The tie's a nice touch... and that wig Halloween hue is heavenly!

Dancing with the Stars and The Real Housewives of Miami star Joanna Krupa dazzled in this most luxurious of celebrity Halloween costumes for the Maxim Halloween bash. Judging by this number for Halloween, her wedding details ought to be impeccably elegant!

Hilary Duff is downright sprightly—love the matching crown and mask—as she made the scene at the Casamigos annual All Hallows Eve soiree.

During another time earlier in her career, Lindsay Lohan could have been a favorite to portray the DC Comics villain, Harley Quinn. After years of scandalous headlines, the once famous actress had to settle for dressing as Quinn for Halloween.

“It's party time!” to quote Jim Carrey from one of his biggest hits—The Mask. Rapper Tyga nailed the look at a Halloween bash in LA.

Karrueche Tran went Native American for her costume as she arrived at the annual Maxim Halloween party.

The Daily Show host gives Eddie Murphy a run for his money in one of the better celebrity Halloween costumes on this list. Trevor Noah is Prince Akeem.

Nicole Scherzinger went the route of the unspecific costume with her visit to Klum’s annual Halloween party. It was certainly a scary look, that much is certain. The former Pussycat Dolls leader scored points for bringing attitude with her get-up.

Supermodel Claudia Schiffer appeared to be channeling a “race girl” as she arrived at Jonathan Ross’ annual Halloween party with her boyfriend, director Matthew Vaughn.

Tara Reid is downright devilish with her contribution to the landscape that is celebrity Halloween costumes. Her skinny figure has people worried, though!

The singer, Joe Jonas, and a singer’s daughter, Zoe Kravitz, are both fantastically festive at a Klum Halloween party. The Jonas Brothers member utterly nailed the Derek Zoolander “Blue Steel” look!

Heidi Klum went all out for her 17th annual Halloween party. Can you imagine the hours it took for her to become the titular character from the iconic Michael Jackson video, “Thriller?”

American Idol veteran Adam Lambert went the extra mile and embraced the theme of his annual Halloween party at the Beverly Hilton Hotel. The Ghost Town Halloween bash host looked ready to shout, “Der’s gold in dem dere hills!”

Grease is the word for model Gigi Hadid, who gave an astounding physical manifestation of Olivia Newton John from the iconic movie musical.

The husband of actress Jessica Alba looks ready to take off. Cash Warren is clearly channeling Maverick from Top Gun. What Alba is going for… not as clear.
