Many stars of CBS Television Studios’ shows paid a visit to Children’s Hospital Los Angeles on December 4th to bring some holiday cheer to the patients and their families. Katharine McPhee and her Scorpion co-stars  Ari Stidham, Jadyn Wong, and Eddie Kaye Thomas were amongst those in attendance.

Check out some photos and a video of the visit below. Kat and Ari put on a little sing-along for the kids and you can hear them jamming out to “Santa Claus Is Comin’ To Town”!
