Jane Marczewski, who goes by the stage name Nightbirde, had Simon Cowell hit his Golden Buzzer as she delivered an impeccable performance of her original song.

So who is Nightibirde and why did the panelists Simon Cowell, Sofia Vergara, Heidi Klum and Howie Mandel find her story so moving?

What is June Aka Nightbirde’s story?

Nightbirde is a 30-year-old from Ohio who is battling cancer. She revealed to the judges that her original track “It’s Okay” narrated her life in the past year, her journey as a cancer patient and how she navigated it.

Nighbirde further shared that the last time she checked, the cancer had spread to her lungs, spine and liver. But what followed was a beautiful melody that left everybody speechless and the singer received a standing ovation at the end of her act.

The judges were unable to hold back their tears and heaped Nightbirde with praise for her powerful performance. While Howie said, “That felt like the most authentic thing I've heard this season”, Heidi added, Nightbirde’s song gave her “chills”.

Cowell, who at first caught everybody off guard saying he was "not going to give a 'yes' for her performance”, went on to smash the Golden Buzzer, sending her directly to the final live shows.
