Jesse McCartney and Adrienne Bailon team up for a day at UCLA Mattel Children’s Hospital in Los Angeles on Saturday afternoon (December 8).

Working with the Ryan Nece Foundation, the duo, along with Julissa Bermudez and Alex Jacke, met with patients at the facility where they made arts and crafts, tree decorating, and made ornaments.

Jesse, Adrienne and Julissa also stopped by patient’s rooms who weren’t able to make it out to the common room. They delivered Christmas trees and a gift.

“Today at The Mattel Children’s Hospital. Everyone needs a little Christmas!” Jesse wrote.

Adrienne added, “Tis’ the season… So happy to join The Ryan Nece Foundation to hand out Christmas gifts at UCLA Children’s Hospital!”
