CELEBRITY CRUSH: At Demna’s farewell show for Balenciaga, you couldn’t move without stepping on someone’s train.

Among the celebrities who gathered at the house’s haute couture salon on Avenue George V in Paris were Lauren Sánchez Bezos, fresh off her wedding to Jeff Bezos in Venice; Nicole Kidman; Lorde; Naomi Watts and her daughter Kai Schreiber; Cardi B; Michelle Yeoh; Salma Hayek Pinault; Patrick Schwarzenegger, and K-pop star Juyeon.

Sánchez Bezos, carrying a personalized version of Balenciaga’s trompe-l’oeil coffee cup clutch bag, was among the first to arrive. “The wedding was incredible,” she gushed. “The dresses were amazing, but being with everyone that I loved, I’m actually teary-eyed thinking about it — it was the most magical three days of my life.”

She caught up with fellow guests including her Blue Origin crewmate Katy Perry, who was unable to make it to the nuptials because of tour commitments. Sánchez Bezos said her fondest memory of Demna’s decade-long tenure was wearing a glossy black gown he designed to the Living Legends of Aviation Awards last year.

“It was really my first couture dress ever, so it wasn’t even just about where I was going, but that I got to wear my first couture dress in my whole life, and it’s a memory I’ll never forget,” she said. “He’s an artist.”

Perry, who memorably showed up naked under a fur coat this time last year, opted for a sculptural black blazer dress with a portrait neckline. What she liked best about Demna’s designs was being able to feel luxurious, even in his more casual ready-to-wear looks.

“All of the materials, though they look distressed and dystopian, were always of the highest quality, so you had that feeling inside of you of luxury, while still maintaining your own sense of style and cool,” she said.

She praised the Georgian designer, who’s preparing to join fellow Kering-owned brand Gucci, for staying true to himself. “He follows his compass, and that’s hard to do when you’re part of a big, big company. It’s a fight,” the “Roar” singer said.

Guests did not shy from donning some of the designer’s more out-there designs. Lisa Rinna, sporting a bowl wig, was wrapped in an electric blue parka gown. Lorde came in a see-through silver chainmail dress, though she was careful to add nipple pasties.

Performance artist Alexis Stone channeled Anjelica Huston as Morticia Addams — complete with the hand known as Thing on his shoulder. Meanwhile, Cardi B vamped it up for fans on the sidewalk in her sheer black négligé dress, which she flipped up to show off the rose tattoo on her backside.

Inside the venue, French singer Aya Nakamura said the high point for her was releasing a capsule collection with Balenciaga in 2022. “C’est le must,” she declared, noting the line promptly sold out.

Watts appeared in two campaigns last year for the Rodeo and Bel Air handbags, alongside Isabelle Huppert and Kim Kardashian, who were part of this season’s stellar runway cast. The “Mullholland Drive” star paid tribute to Demna’s inventiveness.

“He’s his own person, and so modern, so edgy — never too far, though. It just feels like there’s always something wearable, even in these dramatic shows,” Watts said. “I mean, I’m small, I can’t wear some of those clothes, but there’s ways to do it, and he’s literally reinventing the wheel every time.”

Back in 2023, Vittoria Ceretti shot a campaign at the couture salon while it was still under construction — a typically counterintuitive move.

“Demna is such an incredible creative that always managed to bring up new things and new ideas and always surprises and shocks us with his creativity,” the Italian model said.

“He does his own thing, and I think that’s the best possible way to do it as a creative. But sometimes fear gets in the way, and it feels like he’s fearless and he doesn’t care,” she said. “He will just do his own thing and it always turns out to be amazing.”

For Juyeon, a member of boy band The Boyz, Demna saved the best for last. “I’ve been watching his career, and I think this show is the most special moment,” he declared.
