LOUISVILLE, Ky. (WDRB) -- A tiny guitar, a tiny voice and a powerhouse: Taylor Swift surprised Jordan Lee Nickerson at the Boston Children's Hospital.

The 6-year-old was diagnosed with a rare genetic condition known as Williams Syndrome when he was 9 months old --and just last month, his family learned he has Leukemia.

But pain and worry were washed away with Swift's song "We Are Never Ever Getting Back Together."

The two even busted a move. They also talked about Spiderman.
