PHOENIX -- Singing in front of an audience has never been a problem for 17-year-old Karlie O’Hearn.

Singing in front of 50,000 people? That’s a little different.

“I was so nervous,” said O’Hearn, a junior at Centennial High School in Peoria. “My legs were shaking. I was like, what’s wrong with me?

These were the recollections of O’Hearn shortly after performing the national anthem at Chase Field for the Diamondbacks opening day game against the St. Louis Cardinals.

It was a thrill for the lifelong D-Backs fan who ‘brought down the house’ with a stirring rendition.

Overcoming show business nerves however, pale in comparison to what O'Hearn went through 12 years ago when she was diagnosed with leukemia.

“I don’t remember much,” said O’Hearn. “I do remember it was harder on my parents as I was constantly in and out of hospitals.”

O’Hearn eventually beat cancer and has been in remission for 12 years. 

“Cancer has made my life better, she said. “I now just live life to the fullest.”

Now Karlie O’Hearn is focused on a singing and acting career. She shares an unbreakable bond with her mother and her father, Chris, who missed his daughter’s opening day performance as he’s currently serving in the Navy.

“It was sad,” Karlie said. “It was recorded and he texted me right after and said, ‘you did such a great job. I always knew you were a superstar.’”
