Ten years ago, Robert Irwin watched as his sister, Bindi, won Dancing With The Stars and took home the Mirrorball trophy. Now, it’s his turn, and the 21-year-old has been wowing audiences with his incredible dancing ability.

Robert was just 11 when Bindi danced on the show, and he watched from the sidelines every week. The Wildlife Warrior is now sharing the experience with his four-year-old niece, Grace, and has described it as a “full circle” moment for him.

Taking to Instagram, Robert shared an adorable video of him and his dance partner, Witney Carson, teaching Grace how to dance, with the pair giving her a perfect score for her moves.

Grace especially loved being spun around by Witney at one point, looking in the mirror with wide eyes.

“I love when Grace stops by rehearsals and we can teach her some new dance moves,” Robert wrote.

“I’m so lucky to be her uncle.

“Makes me think about when I was a little kid watching my sister in rehearsals on her season of DWTS, it really is a full circle moment.”

Robert’s mum, Terri, commented, saying: “Grace is living her best life!”

“She’s so happy,” Bindi added.

“We just witnessed a core memory in the making,” one follower added.

Many others said that they’d be watching Grace on Dancing With The Stars next, and some said that she is “a mini Bindi”.

It comes as Robert prepares to do a dance inspired by one of Bindi’s Dancing With The Stars performances, which was dedicated to their dad, Steve Irwin.

It comes after Robert and Grace dressed up as Cinderella and Prince Charming for Halloween, and fans absolutely loved it.

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

His mum, Terri, praised Robert for making Grace’s “dream come true”.

Bindi also shared a heartfelt message to her younger brother.

“Thank you for being such a wonderful uncle and brother and friend. We love you so much,” she said.

“You just made Grace’s entire year.”

One fan joked that everyone was “collectively falling in love with Robert” after seeing the video (and perhaps after watching him dance shirtless?).
