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.
