Sunday night was the first time theSome Like It Hotcast heard the announcement too, as they gathered on stage to share a celebratory toast before the show.

Carey had treated the actors to bottles of champagne in honor of their opening night. And as her voice echoed out through the auditorium, company members feigned fainting spells as others gasped, clapped and cheered.

It wasn’t just Sunday night, though. Carey’s voice will welcome ticket holders, remind them to silence their cell phones and send them off to enjoySome Like It Hoteach night at the theater.

The music icon joined the producing team ofSome Like It Hotin late November. She said she was drawn to thestage musical adaptation of the 1959 MGM filmof the same name because of her love forMarilyn Monroe, one of the show’s first actress.

“To see how this show continues to expand on the film’s legacy — pushing boundaries, promoting inclusion, celebrating diversity — I’m proud to help bringSome Like It Hotfor today’s world to new audiences,” she continued.

This is the first time Carey has ever produced a property on Broadway.

Set in Chicago “when Prohibition has everyone thirsty for a little excitement,“Some Like It Hottells the story of two musicians who flee the Windy City after witnessing a mob hit. “With gangsters hot on their heels, they’re on the run as the newest members of the swingingest big band ever to cross the country,” reads a logline for the show. “Can they hide in plain sight without completely losing themselves? Or will the mob, the truth, and maybe even love itself finally catch up to them?”
