Katy Perry, John Legend Headline Charity Auction in Capri for UNICEF

“I’ve seen the craziest things. I’ve seen kids in plastic bags wrapped with regular desk lamps to swaddle the kids. They really try anything and everything,” said Klum. Reflecting on her more than 10 years as an ambassador, she added, “There are so many bad things happening in the world. But how can you ever say no?”

Switching gears in her sparking silvery Elie Saab gown, the Making The Cut co-host also volunteered that picking Season 2’s winner was a hard-fought victory as the series is about to debut its final episodes. “We fought until, I want to say, maybe 2 or 3 am in the morning? Because we all fought for our favorite, which is great,” she said. “It was not unanimous, which I kind of love too. Everyone got their ‘feist[iness]’ out, especially Jeremy,” referring to the show’s new judge, Moschino designer Jeremy Scott.

Klum was one of a bevy of bold-faced names that stood out in the well-heeled crowd, including Perry’s other half, actor Orlando Bloom, who came onstage to help goose bids for the completely restored Steve McQueen race car, even sitting in the seat with a glass of champagne. Actress Vanessa Hudgens and model-actor Jon Kortajarena (whose hustler character memorably tried to seduce Colin Firth’s character in Tom Ford’s A Single Man) also cheered the crowd on during the auction, which also included striking artworks by Andy Warhol and Alex Israel, a notebook of Pablo Picasso’s sketches and a Carrera marble Mickey Mouse by Rome sculptor Gaultiero Vanelli. Also spotted during the evening were the likes of Dylan Penn, Natasha Poly, Emily Ratajkowski, Nicky Hilton Rothschild and Karolina Kurkova.

In a can’t-miss-it chartreuse Matičevski gown, Food Network star and founding board member of the Los Angeles UNICEF chapter Sandra Lee also hit the red carpet. The former girlfriend of New York governor Andrew Cuomo took the arm of People magazine editor-in-chief Dan Wakeford and his spouse, actor Lucas Baker, who were among a contingent of American guests as LouisaViaRoma gears up for its renewed U.S. online launch effort next month.

In a throwback to a group of Slim Aarons’ photographs that were also up for sale during the evening, Perry, summoning the fabled style of the Mediterranean glory, appeared on the red carpet, with Bloom, dressed in a vintage black-and-cream Pierre Cardin couture gown with dramatically bowed statement sleeves.

Later onstage she switched it up as the golden girl of the night in a gilded sequined sheath with floaty chiffon cape by Dolce & Gabbana. After Legend had wowed the crowd with his standards and an especially reflective post-pandemic take on George Harrison’s “Here Comes the Sun,” the throng surged to the stage for Perry’s set, iPhones aloft as she exhorted them with the familiar “Let’s Go All the Way Tonight.” Cooing “Isn’t it so nice to be out again with friends again” — after wrapping up the Breakfast At Tiffany’s theme song with Legend — she launched into the never-more-appropriate “Firework” that resounded above the pink-tinged lights into the Italian night sky above.
