Simon Cowell himself said it! He thinks this 12-year-old girl will be the next Taylor Swift. Grace VanderWaal auditioned for 'America's Got Talent' with only her voice and her ukulele, and immediately won America's heart by simply saying that she believes that miracles can happen when asked if she thinks she could win.

Most of her friends and classmates didn't even know she could sing, so I bet she became a star among her peers when she returned to school after she sang her original piece "I Don't Know My Name."

Howie Mandel replied to the title of her song by saying that everyone will know her name, and then he hit the "Golden Buzzer," which automatically sends Grace to the live show. Simon Cowell and Heidi Klum both said at the end of the segment that they wish they could have pressed the buzzer. Check out her audition below!
