Selena Gomez was one of a few celebs to strap on their dancing shoes and hit the dance floor for a good cause on Saturday night (June 23).
The pop star — along with Jack Black and Grey’s Anatomy’s Sarah Drew and Kevin McKidd — stopped by the Children’s Hospital Orange County’s annual Oncology Prom to surprise some fans in formal wear.
Gomez posed for several selfies and goofed off with attendees, many of the teens and young adults who are currently in treatment for cancer or have completed treatment at the SoCal facility.
