Nicole Scherzinger won the Tony Award for best actress in a musical for her performance in a revival of “Sunset Boulevard,” a high-tech, minimal-scenery staging from Jamie Lloyd about a washed-up silent film star, Norma Desmond, who haunts a grand, ghostly Los Angeles mansion. This is Scherzinger’s first nomination and win.

This latest run of “Sunset Boulevard” — based on the 1950 film by Billy Wilder — is dramatically scaled back compared to previous revivals of the Andrew Lloyd Webber show. Instead, the show relies on technology to modernize it for a new audience. It is the type of show that demands vocal and choreographic athleticism, something that Scherzinger — the former lead singer of the Pussycat Dolls — takes on with confidence.

It first opened in London in 2023, winning Scherzinger praise and an Olivier. It then moved to Broadway last fall, and Jesse Green, the chief theater critic for The New York Times, wrote that Scherzinger delivered an “exciting yet exceptionally weird and counterintuitive performance.”

Speaking to The Times in 2023, Scherzinger described her turn as Norma as “grueling.”

“But for many years I have been saying I am using a fraction of my potential, and now I feel I have really tapped into that,” she said.

Before joining the show and after the Pussycat Dolls disbanded in 2010, Scherzinger pursued a solo career with modest success — dropping two solo albums and working as a judge on “The X Factor” and “The Masked Singer.”

She later performed “Don’t Cry for Me Argentina” (from Lloyd Webber’s “Evita”) as part of a TV special celebrating Lloyd Webber, who, along with the director Trevor Nunn, asked her to join the cast of the 2014 revival of “Cats” in the West End.
