On Wednesday's results show, she learned that viewers of the NBC competition show considered her less than perfect. Kelly was not voted among the acts to advance to the final round.
The three finalists ended up being William Close, Tom Cotter and Joe Castillo.
The 16-year-old musician stuck to her guns, however. Earlier in the evening, Kelly admitted that she's often critical of her own performances. Not so with her version of "Perfect."
"I was really, really happy with what I did [Tuesday] night," she said. In another segment, she said, "I've overcome a lot to be here."
Wearing a form-fitting, sparkling dress, Kelly on Tuesday belted out the hit pop song with confidence and precision.
The judges' opinions, however, were mixed.
Sharon Osbourne gave her credit for strong singing. "No shadow of a doubt, you were born with great pipes, as we say in show business."
Osbourne said her song choice was a smart one, too. However, she found the performance lacking in one respect. "That song needs so much emotion ... I wish I had seen more of that from you."
Fellow judge Howie Mandel said, essentially, that Kelly was a solid talent surrounded by super talent. "You had to blow the roof off the place ... I don't think you did something that really stood out."
Howard Stern, disagreed, though. "Your voice was dead on," Stern said. "Could you benefit from more stage moves or better stage presence? Absolutely. But technically, your voice was stronger than anyone else who sang tonight."
After she sang, host Nick Cannon asked her how she stayed calm.
"I realized I had nothing left to lose," Kelly said, and repeated that singing has always been her passion. "It's what I love to do."
Kelly's burst of national exposure came and went quickly, but she's been a familiar face and voice in Hampton Roads for several years. Back in April, she was picked as a finalist in the Sea Level Singer-Songwriter Festival's Emerging Artist Showcase. She won a place in that Norfolk contest based on her original songs.
