On Thursday nightlodibet, Nicole Scherzinger slipped off a pair of black foam slides and padded barefoot down West 48th Street. Fake blood the shade of maraschino cherries was smeared down her collarbones and the neck of her dress.

Ms. Scherzinger, the actress and former Pussycat Doll, had just left the Broadway theater where she is starring as Norma Desmond, the forgotten star of the silent screen, in a revival of “Sunset Boulevard.”

She was headed to to the Hard Rock Hotel, where Heidi Klum was hosting her 23rd annual Halloween party, and Ms. Scherzinger had deemed her bloodied stage costume gory enough to keep on for the rest of the night.

“At least eight Norma Desmonds showed up to the show,” Ms. Scherzinger said. She hoped to see even more inside the party. “Babe, anyone dressed as Norma Desmond’s going to be the best one.”

Each October, Ms. Klum, the model and former “Project Runway” host, summons hundreds of guests to a club made unrecognizable by fog machines, where they show off impressive, outrageous costumes that are still somehow less impressive and outrageous than hers.
