Demi Lovato and Nick Jonas are set to kick off their joint tour in June, but this week, they treated the patients at Children's Hospital Los Angeles to a special preview.
The two singers backed each other up on hits like "Confident" and "Jealous," then met with kids, parents and hospital staff -- all of whom were thrilled.
"I think it helps the kids feel special," said one child life specialist. "When they're in the hospital so much, they think they're left out of a lot of normal things.
"They got their own concert here today, so they got to have something that was special for them," she added.
