The New Jersey-bred diva roared through the pop song, performed by both Lovato and Idina Menzel
While the "Frozen" soundtrack slips from No. 1 to No. 2 on the Billboard 200 this week, its lead single is getting some love from the K-pop scene. American-bred soloist Ailee performed Demi Lovato's version of "Let It Go" on South Korean live music/talk show "You Hee-Yeol's Sketchbook."
The K-diva -- whose new single "Singing Got Better" is at No. 5 on the K-Pop Hot 100 -- roars through Lovato's pop-rock hit with ease. She hits the big belts and tones down the diva riffs on the verses, all the while looking like she's having a blast.
Despite spending the last two years actively promoting in South Korea, the New Jersey native opted to go with the English version of "Let It Go." Though, had she wanted to sing in Korean, the 24-year-old had the option of a K-pop version, originally sang by Hyorin of super-popular girl group SISTAR.
In late 2013, Disney had announced plans to have singers from around the world record local versions of the soundtrack single to play during foreign releases. Versions were recorded for Mexico, Russia, Italy and beyond.
Listen to Hyorin's version and watch its accompanying music video below. While the K-pop star spends most of the visual singing in a empty room in a curve-hugging short dress -- a la her "Gone Not Around Any Longer" video -- she switches to a long white gown during the last chorus, looking like an actual Disney princess.
