Grace VanderWaal continued her ascent on America's Got Talent with the premiere of yet another original song on Tuesday night's (Aug. 30) semi-finals.

Beginning a capella, the 12-year old singer busted out her ukulele and performed "Light the Sky," a simple song that showed off the rasp in her voice.

Accompanied by a cellist and a percussionist, VanderWaal sang the song's uplifting lyrics -- "I can't stop dancing like no one's around/And yeah, I think we were born to shine."

"You are the real deal," said judge Heidi Klum, who predicted VanderWaal will sail straight to the finals.
