Watch here as Harper Gruzins prove she can sing:
Karlis Gruzins, the girl’s father, said that many “mean and hateful” things had been said about his daughter.
The video of her performance show players and crowds watching in shock as Harper sang.
Harper said she couldn’t hear herself due to the blow horns and crowd cheering. She admits it wasn’t her best performance.
Mr. Gruzins said that criticism about her was mean and that it was “sad that people want to take it to this type of extreme.”
“We believe in our daughter, we support our daughter,” he said.
