Robert Irwin recently turned 22.

But despite his growing status as a Hollywood star, the television star settled for a small family gathering to mark the occasion.

Already in South Africa to film the new season of I’m a Celebrity… Get Me Out of Here! Australia, Robert kept things intimate.

‘My life is dangerous and adrenaline-filled enough without the party vibe, I don’t need any more danger,’ he told The Daily Telegraph.

‘It was actually quite nice because it had been such a crazy time that I had a nice little kind of small celebration with my family, with my friends,’ he added.

Robert was joined by his co-host Julia Morris and had ‘an early night.’

‘It was actually a very restful birthday which I don’t think many 22-year-olds are having an early night on their 22nd birthday but here we are,’ he said.

The nixed party plans come after claims that Robert is reportedly at serious risk of burnout.

The nature conservationist, who just last month won Dancing With The Stars US and is now working on I’m A Celebrity… Get Me Out of Here, is said to be struggling to keep up with his very busy schedule, reported New Idea.

An alleged close source has revealed that the always cheerful Aussie star appeared agitated and not himself when arriving at rehearsals recently for the dancing reality show, sparking fears he may be juggling too many projects.

‘The enormous pressure on Robert right now is multifaceted,’ the insider revealed, adding that Robert is trying to keep everyone happy at his own expense.

It was claimed that Robert opted not to attend a party for his 22nd birthday at Australia Zoo on December 1 – an annual tradition for the Wildlife Warrior – because of his overwhelming workload.

Robert’s hard work has seen him and his partner Witney Carson win the coveted Mirrorball Trophy.

Straight after the show’s final episode, he flew to Johannesburg to begin production in the jungle, with ‘barely a minute’ between filming.

‘Robert’s schedule is out of control,’ the insider alleged, a factor that Network Ten are said to be ‘genuinely worried’ about

‘Robert’s schedule is out of control,’ the insider alleged, a factor that Network Ten are said to be ‘genuinely worried’ about.

Fears that Robert will be too ‘exhausted’ when he begins filming for I’m A Celebrity… Get Me Out Of Here have plagued Ten, who have moved ‘heaven and earth’ to accommodate the young star’s in-demand work schedule.

The cracks began to show for Robert as he broke down in tears during a moving performance on Dancing With The Stars US.

The celebrity conservationist left viewers stunned during a touching Foxtrot 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.
