Taylor Swift Serenades An Adorable Young Cancer Patient at Children's Hospital

Taylor Swift once again proved she's one of the nicest stars in the business, when she visited seven-year-old cancer patient Jordan at Boston Children's Hospital Sunday, who's currently battling leukemia.

Though while the Trouble singer, 24, singing her hit We Are Never Ever Getting Back Together is the obvious focus of the video, Jordan's big personality is scene-stealing in itself, as he enthusiastically sings along and dances to an acoustic guitar-playing Taylor.
