In a surprising twist, Prince William made an unexpected appearance on “Dancing With the Stars” on Tuesday to cheer on Robert Irwin.

The 43-year-old Prince of Wales caught viewers off guard when he joined the show via video call, connecting with Irwin and his dance partner, Witney Carson. During the call, William shared a light-hearted moment with Irwin, humorously referring to him as “twinkle toes” and expressing that he missed him.

During their conversation, Irwin inquired about the recent Earthshot Prize ceremony held in Rio De Janeiro on November 5. Although Irwin was initially slated to attend the event alongside the prince, he had to withdraw due to his ongoing participation in the “DWTS” competition.

With a warm smile, William remarked, “I need you down here,” expressing his desire for Irwin’s presence at the event.

He also encouraged the dancing duo, playfully teasing Irwin before adding, “You guys have got a serious good chance of winning,” as he showed his support for their efforts on the show.

“Best of luck on the show,” he added.

After William hung up, Carson was visibly shocked that they chatted with the royal on video.

“I can’t believe he just said my name,” Carson said.

Irwin added, “Let’s not mess this up!”

Fans also reacted with shock at William’s surprising cameo on the ABC show.

“Prince William on #DWTS was not on my bingo card. Pretty cool!,” one fan wrote on X.

“This is actually insane,” a TikTok of the moment also read.

Another fan joked in reference to Zac Efron not being in the ballroom to support his brother, “DWTS” contestant Dylan Efron, “How did they get Prince William to zoom in but they can’t get Zac Efron to give his brother a call.”

Irwin is an ambassador for the Earthshot prize, a global environmental award founded by William and The Royal Foundation to find and fund solutions to the world’s greatest environmental challenges.

In June, William surprised Irwin with a voice note during the 21-year-old conservationist’s appearance on UK radio station Radio 2.

“I know you’ve got the fantastic Robert Irwin on the show this morning, a brilliant ambassador for the Earthshot Prize,” he said at the time.

During Tuesday’s episode of “DWTS,” Irwin performed a Foxtrot to “Footprints in the Sand” by Leona Lewis. He and Carson received their first perfect score of the season for the emotional performance, which was in part dedicated to his late father, Steve Irwin.
