Paris Jackson Makes a Rare Appearance with a Mystery Man, Martha Stewart Courts Controversy, and More Unforgettable Celebrity Halloween Looks of 2026 — Photos

Halloween 2026 brought Hollywood some unforgettable transformations, but the biggest surprises weren't always hiding behind the costumes. One star arrived with a mystery man, another brought a piece of Hollywood history back to life, and one seemingly playful photograph eventually led to a public apology — so let's take a closer look at five celebrity Halloween appearances and the unexpected stories behind their photos.

Paris Jackson — A Year After Her Engagement Ended, Who Was at Her Side?

Paris Jackson was among the familiar faces celebrating Heidi Klum's annual Halloween party in New York City. Yet while the 28-year-old singer and actress embraced the festive atmosphere, the man standing beside her gave people another reason to take a closer look.

Jackson has spent much of her adult life balancing a public career with a personal life that often attracts unwanted attention. And after what happened to her relationship in 2025, seeing her enjoying a glamorous evening with a new companion was particularly intriguing.

In the summer of 2025, Jackson confirmed the end of her engagement to music producer Justin Long, following photographs that showed her visibly upset. The emotional pictures initially sparked questions about what had happened, until she revealed they were connected to their breakup.

Jackson later opened up about her decision, explaining why she had called off the engagement. It was the end of a relationship that had once seemed headed toward marriage, and her next romantic chapter would soon attract fresh attention.

By June 2026, Jackson had been photographed outside a Los Angeles recording studio with a man who wasn't immediately recognizable to many of her followers. Their outing attracted attention, especially because they appeared to share more than a casual interest in music.

The two were later spotted together at an airport, wearing similarly relaxed, bohemian-inspired outfits. By the time they arrived together at Klum's October celebration, the identity of Jackson's mysterious companion was becoming a much bigger part of the story.

The man was Hayden Karchmer, a Texas musician who performs under the name The Hill Country Devil. His music draws from folk and country traditions, giving him a natural connection with Jackson, who has spent years developing her own sound beyond the legacy of her famous family.

And the two had already taken their shared passion into the recording studio. On August 29, Jackson released new music, including "just you and me," a song she co-wrote with Karchmer on the birthday of her late father, Michael Jackson.

Their shared musical interests, the outings earlier in the year, and now this rare red-carpet appearance gave fans a fuller picture of the man spending time with Jackson. The Halloween photographs captured a new chapter in her life, one in which her personal world and creative ambitions appeared to overlap.

And Jackson wasn't the only celebrity who arrived with someone special. Kyle MacLachlan also had his longtime partner beside him, although the most surprising thing he brought to the party had been waiting in his Hollywood past for 32 years.

Kyle MacLachlan — Why Did His Halloween Costume Have a 32-Year-Old Secret?

Kyle MacLachlan also made a memorable appearance at Klum's Halloween celebration, accompanied by his wife, Desiree Gruber. The couple have been married since 2002, marking 24 years as husband and wife in 2026 — a lasting Hollywood romance that made their joint appearance especially charming.

The actor and Gruber first met in 1999, long before social media became part of everyday celebrity life. They've since shared decades of premieres, celebrations, and family milestones, but this particular evening came with a surprise from a much earlier time.

For his Halloween appearance, MacLachlan skipped the predictable celebrity costume in favor of something that might make longtime movie fans feel suddenly nostalgic. His outfit looked as though it belonged to another era of Hollywood, when family comedies filled theaters and their larger-than-life characters became childhood favorites.

In recent years, MacLachlan has embraced his playful side on social media, entertaining fans with humorous videos and unexpected appearances. His lighthearted posts have introduced him to a younger audience, and Halloween 2026 gave him another chance to show off his sense of humor — this time with a surprising connection to his Hollywood past.

The inspiration came from the 1994 live-action comedy "The Flintstones," in which MacLachlan played Cliff Vandercave, Fred Flintstone's scheming coworker. The family film brought the beloved animated world of Bedrock to the big screen, and more than three decades later, MacLachlan decided it was time for Cliff to return.

But there was a twist: the actor wasn't simply wearing a freshly made replica of his movie costume. He revealed that his outfit was the original costume from the 1994 film, bringing a genuine piece of his Hollywood history onto the Halloween red carpet.

MacLachlan even joked that the people responsible for keeping track of the original outfit might not know it had gone missing. The thought of an actor turning up at a Halloween party wearing something from a movie set 32 years earlier made the whole appearance even funnier.

For viewers who grew up watching "The Flintstones," the costume offered a delightful trip back to the 1990s, complete with an original piece of movie memorabilia. But if MacLachlan's throwback inspired a smile, Neil Patrick Harris and his husband were about to bring a much creepier piece of Hollywood history back to life.

Neil Patrick Harris — Even Fans Couldn't Believe the Resemblance

Neil Patrick Harris has never been one to approach Halloween halfheartedly, and his husband, David Burtka, has happily joined the fun for years. Their elaborate costumes have become something of a tradition, sometimes involving their entire family and often requiring a remarkable amount of imagination.

The couple have been together since 2004 and married in Italy in 2014, building a life that also includes their twins, Harper and Gideon. Their shared love of Halloween has given the family plenty of opportunities to turn an ordinary holiday into something wonderfully theatrical.

Their children, born in 2010, have often joined their parents for elaborate family celebrations. Looking through their family photographs, it's easy to see how dressing up together became one of their favorite traditions.

Over the years, the family has transformed itself into characters from art, film, and popular culture, and their coordinated Halloween looks have earned plenty of attention. This time, though, Harris and Burtka left their usual appearances behind so completely that even longtime fans had to look twice.

At Klum's party, the two men appeared with pale faces, matching hairstyles, coordinated dresses, and nearly identical expressions. Standing side by side, they looked almost like mirror images, creating an eerie effect that was difficult to ignore.

The inspiration was the Grady twins from the 1980 horror classic "The Shining." Harris and Burtka recreated the iconic characters with blue dresses, pink accents, wigs, ghostly makeup, and blood-stained details, bringing one of cinema's most unsettling images to a glamorous Hollywood party.

Their transformation quickly attracted amusing reactions. Under a Facebook video showing the couple's Halloween looks, one viewer asked a particularly funny question: "Olsen twins?"

And that comparison had an unexpected connection to the couple's past. Back in 2019, Harris and Burtka had actually dressed as Mary-Kate and Ashley Olsen, making the comment a surprisingly perfect throwback to another one of their Halloween transformations.

Another viewer couldn't resist joking about how alike the men looked, writing, "I mean they do say married couples start to resemble each other." After so many years together, the observation was especially amusing, considering how thoroughly the couple had embraced their matching identities.

A third person went even further: "They look exactly the same. They are morphing into each other". With their matching makeup, wigs, outfits, and expressions, the pair had created an illusion that made it difficult to tell where one character ended and the other began.

For a couple who have spent years finding new ways to entertain themselves and their children, this was another Halloween memory worth keeping. Their costumes were spooky, hilarious, and almost unbelievably convincing, proving that they hadn't run out of creative ideas after all those years.

But while Harris and Burtka embraced horror, Paris Hilton had a very different vision for Halloween. Her celebrations included glamorous gowns, elaborate hairstyles, and several completely different transformations — although one family decision would soon have people talking for reasons she hadn't expected.

Paris Hilton — Fans Loved Her Princess Makeover, but Then They Saw Her Daughter's Costume

Paris Hilton took Halloween 2026 to another level, appearing in several striking costumes that showed completely different sides of her personality. But while one transformation had fans calling her a real-life princess, another sparked an unexpected controversy involving her young daughter.

At Christina Aguilera's annual Xtinaween celebration, the 45-year-old star appeared as an enchanting fairy, wearing a romantic fantasy-inspired costume. Her husband, Carter Reum, accompanied her to the glamorous event, where Hilton also posed alongside Aguilera.

But Hilton had another surprise planned, and this one involved a much more dramatic transformation. Before revealing it, she had shared photographs of her usual appearance on Instagram, giving fans a glimpse of her familiar blonde hairstyle before its fairytale makeover.

When Hilton finally revealed her next look, she had transformed into Rapunzel from Disney's "Tangled." Wearing a lavender gown and an extraordinarily long blonde braid decorated with flowers, she looked almost unrecognizable from her earlier photographs.

The transformation quickly won over fans, especially her dramatic hairstyle. One admirer wrote, "You look amazing! That hair and dress combination is total perfection💜💫✨", while another exclaimed, "That dress omgggg".

The compliments didn't stop there. "My favorite real life princess. Magic hair day, I just love it 🥰🥰🥰", one fan commented, while another declared, "I’m obsessed with all these looks 😍😍😍😍".

Fans were clearly loving every look, showering Hilton with compliments over her glamorous Halloween transformations. But while her princess-inspired costumes were winning hearts, another family look was about to spark a very different reaction.

For another Halloween celebration, Hilton and Reum recreated "Beauty and the Beast" with their children. Paris became Belle, Carter dressed as the Beast, their son Phoenix portrayed Lumière, and their daughter London appeared as Chip, the little teacup.

But some viewers criticized Hilton for choosing the princess role for herself instead of her daughter. The family photographs unexpectedly sparked a parenting debate, with people questioning why London hadn't been dressed as Belle.

Hilton quickly defended the decision, explaining that London had chosen Chip herself. The little girl already knows what she wants, her mother explained, offering a sweet reminder of how determined young children can be about their favorite characters.

And Hilton's family wasn't finished dressing up. They also recreated "The Addams Family", with Paris as Morticia, Carter as Gomez, London as Wednesday, and Phoenix as Pugsley — swapping their colorful Disney costumes for a completely different Halloween mood.

Hilton's Halloween celebrations brought princess glamour, family fun, and unexpected criticism into one eventful holiday. But while her costume controversy centered on a little girl's choice, Martha Stewart's Halloween look was about to ignite a far more serious backlash — and even lead to a public apology.

Martha Stewart — The Handwritten Sign That Turned Her Halloween Into a Scandal

For decades, Martha Stewart has been known for elaborate holiday celebrations, and Halloween has always been one of her favorites. The lifestyle icon has never shied away from unusual costumes, but her 2026 choice sparked a reaction she hadn't anticipated.

At 85, Stewart prepared another surprising look. Yet when photographs appeared online, the response was far from the usual laughter and excitement.

Stewart has often embraced playful humor, from theatrical costumes to appearances alongside Snoop Dogg. Their unlikely friendship has revealed a fun-loving side of the woman best known for her elegant approach to home and entertaining.

But this Halloween, she traded glamorous outfits for worn clothing, deliberately messy makeup, and a handwritten sign. Once the full costume appeared online, the backlash began almost immediately.

Stewart had dressed as a person experiencing homelessness, wearing distressed clothes and makeup intended to imitate dirt. She held a sign asking for food and help, prompting angry reactions from people who felt homelessness was being turned into a Halloween joke.

The original post also promoted Stewart's candle products, intensifying the controversy. Critics questioned why an image depicting someone without a home had been used alongside a commercial promotion.

As criticism spread, social media users argued that poverty and homelessness weren't appropriate costume ideas. Others wondered whether Stewart had intended to raise awareness but chosen the wrong way to do it.

Soon, the photograph disappeared from Stewart's social media account. However, screenshots had already circulated, and people continued discussing the costume after the original post was deleted.

On November 1, Stewart addressed the backlash, explaining that she wanted to raise awareness about homelessness, not mock those experiencing it. She also pointed to her long history of charitable work.

But her first statement stopped short of an explicit apology, leaving some critics dissatisfied. As the backlash continued, people questioned whether she would acknowledge that the costume itself had been hurtful and inappropriate.

Then came a second statement. This time, Stewart acknowledged that her earlier explanation hadn't gone far enough and addressed the costume directly.

In her public apology, she wrote: "Wearing a costume like I did was insensitive and not funny. I'm very sorry." It marked a clear change from her initial response.

The apology drew mixed reactions. Some appreciated Stewart's willingness to admit her mistake, while others maintained that the costume should never have been considered acceptable.

As debate over her apology continued, the incident remained one of Halloween 2026's most controversial celebrity moments. The original photograph was gone, and Stewart had apologized, but the criticism hadn't disappeared with it.

When the Costumes Came Off, One Thing Remained

By the time Halloween weekend ended, the red carpets were empty, the elaborate makeup had been washed away, and the carefully chosen costumes were ready to be packed up for another year. Yet the photographs were still everywhere, capturing moments their famous subjects might never have expected people to discuss quite so intensely.

A costume can be planned down to the smallest detail, but the reaction is never guaranteed. And perhaps that's what made Halloween 2026 so unforgettable: behind all the wigs, glamorous dresses, and spectacular transformations were real stories that kept people talking long after the masks came off.
