Robert Irwin has shared a heartfelt moment with his niece as he continues his journey on Dancing With the Stars.

The 21-year-old Australian TV presenter posted a Halloween video to Instagram, showing him dancing with Bindi Irwin’s daughter, Grace Warrior.

Dressed as Prince Charming, Irwin guided his niece as she enjoyed her own Cinderella moment, dancing to Disney’s “A Dream Is a Wish Your Heart Makes.”

“Promised Cinderella a dance for Halloween. I’m really happy these dancing skills are coming in handy,” he wrote in the caption.

The post generated a strong response from fans, who praised the wildlife conservationist for the sweet gesture.

“ROBERT, stop, we can’t possibly like you any more than we already do,” one commented.

“Sooooooo you really are Prince Charming,” another wrote.

One reflected on the legacy of Robert’s late father, the beloved Steve Irwin.

“Steve’s smile lit up all of heaven watching this! We truly don’t get enough of these moments in today’s world,” a fan said.

There was also playful speculation about Grace following in the family’s dance-show footsteps, with her mother previously winning Season 21 alongside Derek Hough.

“Beautiful Princess Grace, future DWTS!” a follower wrote, while another added, “Start teaching her now and she’ll be the next one to win on DWTS! (Because you’ve won in our hearts at the very least!).”

Messages of support also came from within the family.

Bindi Irwin thanked her brother, saying, “Thank you for being such a wonderful uncle and brother and friend. We love you so much. You just made Grace’s entire year.”

Terri Irwin commented to acknowledge the special moment as well, writing that he made “Grace’s dream come true!”

Robert Irwin remains in the competition after earning a near-perfect score in Week 7. He and professional dance partner Witney Carson will next perform the Paso Doble to “Icky Thump” by The White Stripes for Rock & Roll Hall of Fame Night.
