Initially, Judge Howie Mandel said he liked the singer’s appearance — comparing her to Audrey Hepburn — when she took the stage Tuesday night.

But the judges were not prepared for what Bevier said next. 

“My hair wasn't really my choice. I am a survivor of stage 3 ovarian cancer,” she admitted to the room.

She then broke into song, covering the Rachel Platten hit “Fight Song,” wowing the judges and the audience.

“You’ve gone through an obstacle far greater that anybody older than you could even imagine going through. And you sing that song, your fight song. That was emotional and heartfelt, it was inspirational,” said Mandel.

Notoriously mean Simon Cowell had a big heart for the young singer.

“I love everything about you. I just have this feeling when you walk in. Just your spirit, your song choice, your voice, I think you are something special. I predict something great [is] gonna happen for you,” he said.

Cowell then gave Bevier the Golden Buzzer to automatically advance to the next round.
