Darla Holloway was diagnosed with acute lymphoblastic leukemia in April 2012 when she was just 2 years old. She's currently undergoing chemotherapy, NESN reports, but on Tuesday night, the adorable 4-year-old took a break from treatment to perform "God Bless America" at Fenway Park.
The talented little girl first sang the National Anthem with a Jimmy Fund chorus, before returning during the the seventh-inning stretch to absolutely wow the crowd with her solo.
Darla told radio station WEEI that she practiced everyday before her debut at Fenway. It's safe to say her hard work paid off.
