'Once Upon a One More Time' is now playing on Broadway

Britney Spears is a big fan of a new Broadway show that features her music.

Once Upon a One More Time, a musical based on the pop star's many hit songs, had its premiere night on Thursday in New York City at the Marquis Theatre. On Instagram, Spears, 41, showed her support and wished the cast luck.

"Good luck to the hardworking cast and crew of 'Once Upon a One More Time' on opening night tonight 🌹💃🏼✨ !!! I’ve seen the show and it is so funny, smart and brilliant 🤩 !!!" she wrote.

Billed as the "ultimate revisionist fairytale," Once Upon a One More Time features an original story by Jon Hartmere, and is overseen by director and choreographers Keone and Mari Madrid with David Leveaux as creative consultant.

The show spans Spears's songs like "Oops I Did It Again," "Lucky," "Circus," "Toxic" and more.

The cast includes: Briga Heelan as Cinderella, American Idol's Justin Guarini as Prince Charming, Aisha Jackson as Snow White, Jennifer Simard as Stepmother, Adam Godley as the Narrator, and Brooke Dillman as the O.F.G. (Original Fairy Godmother).

Additionally, there's Ryann Redmond as Stepsister Belinda, Tess Soltau as Stepsister Betany. Gabrielle Beckford as Rapunzel, Ashley Chiu as Sleeping Beauty, Nathan Levy as Clumsy, Ryan Steele as Prince Erudite, Morgan Whitley as Princess Pea, and Lauren Zakrin as Little Mermaid.

Guarini, 44, thanked Spears for her support Thursday, sharing her post on his Instagram Story and writing, "Thank you for everything you've given us and given the WORLD @britneyspears."
