The stunning songstress belted out the film’s classic song “Part of Your World” at Disneyland in California in front of Sleeping Beauty’s castle in front of a live audience.

“First time singing part of your world live since filming,” Halle captioned a clip of the moment.

She also noted that the performance was filmed during the wee hours of the morning.

“Thank you @disneylittlemermaid & @americanidol for giving me the chance to do so on stage at disneyland ..singing vocals in freezing cold weather at 3am in morning while park is closed is no joke but we did it!”

Disney’s The Little Mermaid hits theaters May 26.
