An incredibly shy girl stunned audiences and judges on "America's Got Talent" with a voice from a different time.
But once the music begins, Courtney sparks to life with her jerky dance moves and Steven Tyler-esque voice.
In the audition, Courtney initially comes on stage and awkwardly answers judge Mel B's questions.
Launching into Otis Redding's 'Hard to Handle', Courtney left the judges and everyone in the crowd completely speechless - jaws basically dropped everywhere.
Then, Hadwin opened her mouth and showed off just how big a voice the small teen truly had, delivering a flamboyant and energetic rendition of the iconic tune that absolutely blew away everyone in the audience.
13-year-old singer Courtney Hadwin hit the stage for a performance on Tuesday night (June 12) - and her singing skills were so good that Howie Mandel hit the golden buzzer after her audition! "Oh my gosh! You are not from this era. The only thing I can do for you young lady is give you", Mandel explained before hitting the Golden Buzzer.
Each judge gets to press the golden buzzer only once per series for acts they think deserve to go straight to the quarter finals, bypassing the next rounds of auditions.
From the first moment Hadwin began to sing, judge Simon Cowell was absolutely floored, and he had nothing but praise for the incredible songstress after her performance.

America's Got Talent airs on Netflix in the United Kingdom, with new episodes on Thursdays. She later tweeted saying it was "more than I ever could have dreamed of".
