Sisters Quincy and Gracie Latkovski share a passion for dancing. However, while Quincy has full use of her legs, Gracie has cerebral palsy and cystic fibrosis, and uses a wheelchair. None of that stops the 9-year-old from exuding every bit of grace that her name promises though. For her part, Quincy has learned how to perform in a wheelchair, too. At a recent Kentucky competition, the pair danced an unforgettable routine to a cover of Christina Aguilera's "Reflections." Their act, as you can see above, was an absolute inspiration.
