Selena Gomez made a few fan’s dreams come true when she made a special appearance at the Children’s Hospital of Orange County’s Oncology Prom.

Selena Gomez, 25, is a literal angel. On June 23, the “Wolves” singer and a few other stars including Grey’s Anatomy cast members Sarah Drew and Kevin McKidd spent their Saturday night at the Children’s Hospital of Orange County’s 17th annual Oncology Prom. Dressed in a black polka-dot dress, Sel posed for pictures and even joked around with some of the patients at the “Around the World in One Night,” themed event. “@selenagomez at Our photo booth with CHOC children! She is such a sweetheart for spending her time with these awesome kids and creating such a memorable moment they will never forget at CHOC prom night 2018,” photo booth company Pixta Perfect captioned a video of Selena and a patient. We can’t think of anything more heartwarming!
