Robert Irwin fans swoon over his chiselled biceps as the Wildlife Warrior confirms hosting role on US Dancing With The Star spinoff

Robert Irwin has confirmed his hosting role on the upcoming US Dancing With The Stars spin-off.

However, many fans seemed more interested in the size of his biceps.

The Wildlife Warrior, 22, was front and centre at Hulu's Get Real event in Los Angeles on Thursday, where the streamer unveiled its slate of 2026 reality shows – including Dancing With The Stars: The Next Pro, which Robert will host.

He took to Instagram on Thursday to share the announcement with fans via a video that included scenes from the Hulu event.

The clip began with Robert sitting in a car with his Dancing With The Stars partner Witney Carson.

Clad in a figure-hugging tank top, Robert's gym-honed arms were on full display.

'We are on our way to make a very exciting announcement,' he said as Witney flexed her biceps.

'Oh wow,' Robert said as he flexed his own bicep. 'That's not the announcement that we're making. We have something that we've kind of both been working on for a while.'

With that, Robert and Witney fist-bumped before he added: 'Boom.'

The video then cut to Robert at the Hulu event, where he was escorted onto the stage by pro dancer Shirley Ballas, who will serve as a judge on the show alongside her son and three-time Mirrorball champion Mark Ballas.

The announcement elicited a flurry of applause from the crowd, and Shirley was quick to praise Robert.

'Robert is the most amazing host I have ever worked with in my entire life,' she said.

An excited Robert replied: 'I just want to start dancing, Shirley.'   

While many fans were quick to congratulate Robert on the new gig, others were more impressed with the size of Robert's 'guns'.

'No, the muscle-off at the beginning,' one fan offered, adding laughing and flexed biceps emojis.

Another chimed in, begging Robert to divulge his workout routine.

'I really do need that bicep routine and if you say it’s just from wrestling crocodiles I will scream,' they wrote as another added: 'I wasn't ready for the muscles.'

A fourth summed up the sentiment of many with: 'All the women trying to get on his arms lawl.' 

The Next Pro will follow 12 dancing hopefuls vying for a spot as a professional dancer on the next season of Dancing With The Stars.

The group will be joined by a lineup of returning pros who will serve as rotating mentors and guest judges. 

The Next Pro is set to premiere in the US on July 13 on ABC, with episodes available the next day on Hulu.

2026 is proving to be quite the red-letter year for Robert, with sources recently claiming Network Ten is lining up the rising star to front a rebooted Australian Ninja Warrior as part of a major push to lock him in across multiple flagship shows.

'Robert is exactly what Ten needs right now,' an insider told Daily Mail this month, saying the network wants Robert working on more than just I'm A Celebrity... Get Me Out Of Here!

Behind the scenes, negotiations are said to be already underway, with the network keen to position the Wildlife Warrior as the new face of Ten.

However, it would seem that other networks have the same idea, with some of Ten's biggest competitors already looking to poach the in-demand star.

Insiders claim Seven Network has plans to secure Robert as the future host of Dancing With The Stars, following his win on the US version of the series.

'Seven sees huge potential in him,' the insider revealed. 'They think he could take DWTS into a new era.'

DWTS Australia is currently being hosted by Sonia Kruger and Dr Chris Brown.

Daily Mail first reported Robert's involvement with the spin-off in March.
