As she stood on the "America's Got Talent" stage, 13-year-old Evie Clair started to choke up while speaking about her dad.

Her dad had been diagnosed with stage 4 colon cancer about a year ago and given, she says, a five percent chance to live.

"He still continued working and supporting our family," Evie told Simon Cowell and the others.

She was a long way from her home in Florence, Arizona and was there to sing for him.

Evie chose a song close to her heart, one she often sings to her dad on what she called "rough days." The song was Christina Perri's "Arms."

"I sing him this song to help him feel better and just to give him comfort and strength to continue fighting," she said.

Her dad and mom were on the side of the stage as Evie wowed the judges, brought the audience to tears, and touched people at home.

Come Thursday, her emotional performance had won hearts all over the internet.

She earned a standing ovation for her performance.
