It's always very cool when a big time sports hero or a national celebrity makes an appearance to cheer up a sick child and their family!

This past weekend, country superstar Taylor Swift brought her guitar to the Boston Children's Hospital to visit Jordan Lee Nickerson, and six year old boy suffering from Leukemia.

Taylor Swift is Jordan's favorite singer and you can definitely tell!

Swift actually looked a little nervous from all the attention when asking Jordan what he wanted her to sing.  After taking a moment to tune her guitar Swift launched into her hit song "We Are Never Ever Getting Back Together" and invited Jordan to sing along and dance, which he happily did.
