The Little Mermaid star Halle Bailey is blowing one of the movie's most famous songs out of the water in a new performance.

As part of American Idol's Disney night episode on Sunday, Bailey, 23, performed the film's classic song "Part of Your World" at Disneyland in California.

The actress and musician — who stars as Ariel in the new live-action remake of the 1989 animated classic — performed the number in front of Sleeping Beauty's castle at Disneyland, with audience members looking on as they held blue light sticks that were lit to fill Bailey's stage with the glow of the sea.

Bailey belted out the song wearing a floor-length ocean blue gown, as the castle behind her took on a sea-themed background. Fireworks went off behind Bailey as she finished her performance, which comes roughly one week after Disney shared an exclusive clip of another song from the film, "Kiss the Girl," as performed primarily by Daveed Diggs as Sebastian.

At the film's world premiere in Los Angeles last Monday, Diggs, 41, told PEOPLE that he believed Bailey "is the only person who should be playing this role" for The Little Mermaid's live-action reimagining.

"I think it's incredible," Diggs, best known for his role in the hip-hop musical Hamilton, said of Bailey's casting. "Obviously, it's important for Black and Brown kids and for kids of all ethnicities to get to look up on the screen and feel like the story is theirs, too. I'm so thrilled about that."

"I'm also thrilled that it is Halle, of anybody. She's wonderful," he continued. "This is the only person who should be playing this role."
