Selena Gomez is in Australia on her Revival Tour and took the opportunity to surprise one of her biggest fans.

The pop star teamed with local radio station KIIS 1065 to pull a fast one on 22-year-old Sophie Saunders.

While Saunders recorded a video for the radio station, singing Gomez's new song "Kill Em With Kindness," Gomez sneaks into Saunders' house and enters her room. She reveals herself on Saunder's camera screen, with the whole moment caught on video.
