NIGHT OF STARS: Budget cuts? What budget cuts? Kering may be on a cost-cutting drive under new chief executive officer Luca de Meo, but you wouldn’t know it from the bombastic show Saint Laurent staged on Monday night.

The executive, attending his first show at Paris Fashion Week since his appointment earlier this month, could be forgiven for thinking the brand was trying to set a new record of celebrities per square foot.

In a rare appearance, Madonna arrived fashionably late with her daughter Lourdes Leon and boyfriend Akeem Morris. That gave guests plenty of time to take in the pre-show action.

Flashbulbs went into overdrive as Charli XCX took her seat next to Hailey Bieber, Zoë Kravitz and Rosé of K-pop group Blackpink, dressed in a skimpy négligée. Designer Jean Paul Gaultier was sandwiched between Kate Moss and Catherine Deneuve, puffing on her vape.

Renée Zellweger caught up with her “Only Murders in the Building” costar Logan Lerman, turning to admire the Eiffel Tower twinkle. There was a logjam as the likes of Walton Goggins, Christopher Briney, Eva Herzigova and Carla Bruni took turns posing in front of the Iron Lady.

“It’s pretty hard to beat this setting,” said Cristin Milioti, as she surveyed the parterre of hydrangeas on the outdoor set. Fresh off her Emmy win for “The Penguin,” she was gearing up for the November release of the Netflix animated film “In Your Dreams,” in which she voices the character of the Mom.

The American actress paired her croc-effect skirt and ‘80s-style leather jacket with towering Lucite heels. “They’re intense, but worth it,” she said.

Singer Role Model was preparing to head back to the U.S. for a few dates before his sold-out European tour kicks off in early November. “In Europe, it’s very much about the music and then in America, sometimes it’s not, but equally fun,” he said.

He will also appear in Lena Dunham’s rom-com “Good Sex,” due to come out on Netflix next year. “I have not seen it, and I’m very excited to see it,” he said. Will there be good sex? “I don’t know — that’s the question,” he teased.

After the show, Madonna lingered to warmly embrace Gaultier, who famously designed her cone bra for the 1990 Blonde Ambition tour. After a final photo with Central Cee, the “Material Girl” headed off into the night. One can only imagine the after party.
