Darla Holloway may be battling leukemia at just 4 years old, but that didn’t stop her from showing everyone at Fenway Park how it’s done when it comes to belting out “God Bless America”.

Holloway appeared at Fenway on Tuesday night courtesy of The Jimmy Fund, which raises money for cancer patients in the Boston area. After singing the National Anthem, she performed the song guaranteed not to leave a dry eye in the house.

Darla was diagnosed with acute lymphoblastic leukemia in 2012 and is currently undergoing chemotherapy in a two-year plan of treatment. You can listen to an interview with her below.
