Shy schoolgirl, 14, earns a standing ovation from judges for her incredible performance

14-year-old Courtney Hadwin first impressed the judges during the audition round as a shy girl turned into a rock star. But it was only a start of a long journey of defying expectations.

Hadwin started her audition of “America’s Got Talent” as just another shy girl, who is too afraid to face the crowd. But when she held the microphone in her hands, she shocked everyone by adopting a completely different personality.

She won the hearts of many music lovers all over the world with the viral video of her first ever performance during the audition round of “America’s Got Talent.”

During the performance, the seemingly shy British teenager chose Otis Redding’s “Hard To Handle” as the song with which she would impress the judges. And when she started belting out the lyrics to the song, she did just that.

Out of all the judges watching the performance, Howie Mandel seemed most impressed as he later gave her the Golden Buzzer that would send her straight into the finals of the show.

Months later, Hadwin now required to prove her singing ability yet again as she now competed in the semifinals stage of the popular singing reality competition.

After cementing her image as a terrific rock star, Hadwin yet again chose another iconic rock song for her performance, this time opting for Steppenwolf’s “Born To Be Wild.”

As soon as she held the microphone and started belting out the lyrics to the song, she proved everyone once again why she was sent straight into the finals by the judges.

She was just as electrifying and her performance was up to the mark and would have made any rock star proud.

The end of her performance was marked by the entire studio audience rising up to their feet in her appreciation. Even the judges were up on their feet to give her a standing ovation.

This time, judge Simon Cowell seemed to be the one who was most impressed as he quickly ran over to Mandell and gave him a hug for bringing Hadwin straight into the finals.

Cowell later passed his judgment telling Hadwin, "You're a bundle of excitement and it's raw and messy. I saw you at the beginning of the show, shaking like a leaf and then you come out on stage and turn into a maniac," Cowell said. "That's why I absolutely love you."

Mandell used the lyrics of the song to praise Hadwin and told her that she was “born to be wild.” He then added, “This was wild! You were amazing. My prediction is you’re going to be the winner.”

Judge Heidi Klum also praised the young girl but pointed out something unique about her. She told Hadwin that she was impressed by the fact that she chose to stray away from the norm that girls her age should stick to pop songs.

For Judge Mel B, Hadwin has delivered just one minor mistake and that was that the former Spice Girl could “feel her nerves.”

In the after-performance interview on the show, Hadwin expressed her gratitude for Mandell for pressing the Golden Buzzer and for believing in her from the very start.

She also explained that she had learned from the show to not look at the bad comments from haters and to concentrate on the positives.

According to Good Housekeeping, Hadwin was under scrutiny throughout the season for previously competing on "The Voice Kids UK." Many also criticized her by alleging that her shyness on the show was fake.
