Demi Lovato and Nick Jonas paid a visit to Children's Hospital Los Angeles to visit with patients and help make one adorable kid's stay a little brighter.
Jenny and Isaac Zea's 5-year-old son, Aiden, is bravely fighting cancer at the hospital, where he is recovering after getting a bone marrow transplant last week. ET has learned that Nick and Demi came by his wing and sang "Happy Birthday" to him.
As if that wasn't enough, we're told Nick and Demi also took time out to visit other children as well.
