Awwwww! This is so sweet.
Nick Jonas made a special appearance at The Children's Hospital at Montefiore yesterday to bring some joy to some kids!
The Jealous singer surprised the children as part of Musicians on Call, a program that brings music and musical guests to patients all across the country who could use a little something to cheer them up.
Apparently, Nick really connected with the fan pictured above as soon as he got into the hospital, and even sang a duet of Pharrell's Happy with him!
The Kingdom actor also sang Happy Birthday to a girl whose birthday is actually today, as well as his other songs Chains and Introducing Me.
It's so lovely seeing celebs giving back to their fans, especially when those fans are young children!
You rock, Nick!
