Simon Cowell was left in disbelief when he asked a talented young girl to sing a cappella during an audition.

The 12-year-old from Easley, South Carolina, turned a potentially disastrous moment into an unforgettable experience on “America’s Got Talent.”

Ansley began singing Aretha Franklin’s “Think” when Simon abruptly stopped her, criticizing the background music as “horrible, horrible.” Undeterred, Ansley performed the song without any accompaniment, leaving Simon and the audience in awe of her impressive vocal abilities.
