Robert Irwin broke down in tears during a moving performance on Dancing With The Stars US.

The celebrity conservationist, 21, left viewers stunned during a touching Foxtrot with Witney Carson to Leona Lewis‘ ballad Footprints in the Sand.

The heartfelt performance not only paid tribute to Robert’s late father Steve, as a projection of him appeared in the foreground, but also to his sister Bindi, 27, who performed the same song during her own DWTS stint in 2015.

As their dance came to an end, Bindi made a surprise appearance, and joined him – which saw Robert moved to tears.

Clips of a very young Robert with his father were projected onto the ballroom floor, leaving the Australian star overcome with emotion.

He collapsed to the floor and was embraced by Witney and Bindi as the crowd erupted in applause, earning him perfect scores across the board.

Fans were deeply touched by the performance and quickly took to social media to show their appreciation.

‘When Bindi came out I absolutely sobbbbbbbed,’ one person gushed.

‘I will never emotionally recover from this,’ another added.

‘Wasn’t expecting to be moved to the point of actual tears but that ending did it for me,’ wrote one more.

Robert’s powerful performances this year have made him a fan favourite for winning the 2025 season, ten years after Bindi took home the title on the show.

It comes after DWTS US viewers were convinced they’ve figured out which Irwin family member will join next, following Bindi and Robert Irwin‘s incredible stints.

The celebrity conservationist siblings have already wowed audiences with their moves, and now fans believe a new social media clip reveals who’s next.

Earlier this week, Robert teased a snippet of his rehearsals on Instagram, which showed his little niece Grace, four, practising a dance.

She looked adorable in a sparkling black dress as she practised alongside Robert and his dance partner, Witney Carson.

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

‘Makes me think about when I was a little kid watching my sister in rehearsals on her season of DWTS. A full circle moment.’

The footage wowed Robert’s followers, who flocked to the comments to ask when young Grace might appear on the show.
