Simon Cowell is convinced that he's discovered the next Taylor Swift.
The music mogul and his fellow America's Got Talent judges (Howie Mandel, Heidi Klum and Mel B) were blown away by a young girl called Grace VanderWaal.
In front of a huge studio audience, the 12-year-old auditioned for the reality show by playing her ukulele and singing an original song called I Don't Know My Name.
After her performance, VanderWaal received a standing ovation from all of the judges before Mandel hit the golden buzzer, sending the talented youngster straight through to the live rounds.
"Grace, you know what I predict for you?" Simon Cowell said, "I think you are the next Taylor Swift."
