“Robert Irwin Ignites the Internet with Steamy Behind-the-Scenes Underwear Ad Snaps: ‘Who Needs Filters?’”

Robert Irwin continues his streak of captivating posts!

The 21-year-old wildlife advocate and television star shared exclusive behind-the-scenes glimpses of his recent Bonds underwear campaign – an Australian brand expanding to American markets – via Instagram on Saturday, April 5.

Clad solely in sleek black briefs, the snapshots showcase Irwin’s athletic physique during the photoshoot.

“Capturing moments for @bondsaus,” wrote the son of legendary Crocodile Hunter Steve Irwin in his post’s description.

The brand humorously responded in comments: “Absolute icon ❤️ What’s it like conquering social media?”

PEOPLE previously unveiled Irwin’s “Made for Down Under” campaign exclusively. The Australia Zoo personality revealed he had no reservations about his bold photoshoot appearance.

“The decision required zero contemplation,” Irwin stated, continuing: “I’m embracing diverse experiences that push boundaries. If it sparks nerves yet delivers excitement? That’s precisely where I want to be.”

The wildlife expert clarified interacting with reptiles caused no apprehension. “Creatures surrounded me as usual – just with reduced clothing this time,” he remarked with humor.

Irwin emphasized his family’s encouragement, praising sister Bindi and mother Terri: “Their unwavering support fuels everything. They’re our enduring foundation.”

When asked about his father’s hypothetical reaction, Robert chuckled: “You’d likely hear multiple ‘Crikey’ exclamations!”
