Robert Irwin is shedding his signature khaki uniform for something much more revealing—and fans are losing it.

The 21-year-old posed nearly naked in a bold new underwear campaign for Australian clothing brand Bonds.

In the campaign, Robert showed off his toned physique while posing with snakes, spiders, and lizards.

“Proud to celebrate Australia’s most iconic animals—and the most iconic underwear!” he wrote on Instagram.

Fans were quick to react, with one joking, “Chill bro, my wife’s on this app,” while others were left speechless.

Robert, known for following in his father’s conservationist footsteps, admitted the shoot was nerve-wracking.

"Getting your gear off is way scarier than wrangling a croc!" he confessed. "It felt so surreal.”
