Viewers of Dancing with the Stars were left stunned on November 11 when Prince William made a surprise appearance during the show to support contestant and wildlife conservationist Robert Irwin.

While the future King didn’t exactly waltz onto the dance floor, his unexpected video message still made quite an entrance. Appearing on screen, William sent Robert a heartfelt message of encouragement, saying the young conservationist had “a seriously good chance of winning.”

Robert, son of the late Steve Irwin, was about to perform the foxtrot with partner Witney Carson when the video aired. Touched by the royal’s words, he said, “We’re doing this dance for Bindi and for Prince William—so let’s make it count!”

William also added a playful line referencing their shared passion for the environment: “We’re going to save the world… Best of luck on the show!”
