WATCH: Taylor Swift Surprises Little Boy Fighting Cancer – Pair Duet In Cutest Video Ever

Taylor Swift just made one little boy’s day, when she visited him during his treatment at Boston Children's Hospital.

In this clip, Taylor is seen hanging with six-year old super-fan Jordan Lee, who is battling leukaemia. The new firm friends start chatting about everything from Superman to his favourite songs.

When she offers to play him a tune, the little gentleman tells the singer to choose her favourite song.

And he might just happen to join in, in the sweetest way possible.

This is really, really lovely.
