Robert Irwin’s risqué new photo shoot leaves people distracted by one small detail

Robert Irwin, son of Steve Irwin, the beloved Aussie crocodile hunter who sadly passed away in 2006, has left fans well and truly shocked after debuting a pair of tighty whities in a brand-new photo shoot.

The 21-year-old lad - who has clearly followed in the footsteps of his late father after becoming a conservationist, TV presenter, zookeeper as well as a wildlife photographer - has recently teamed up with Bonds, an Australian underwear brand operating since 1915, which is now officially debuting in the US market.

The campaign in question is aptly titled 'Made for Down Under' and sees Robert posing among real-life snakes and crocodiles while donning various colour ways of the boxer-style undies.

Earlier this afternoon (3 April), PEOPLE magazine shared a series of exclusive snaps of Robert promoting the range and, naturally, fans couldn't wait to share their reactions to the saucy snaps with one Instagram user writing: "Suddenly I'm obsessed with crocodiles."

"Whoa! When did this dude become this f*cking hot?" gushed a second while a third chirped: "Crikey!"

A fourth chimed in: "Wowzer!!!!!!"

"Lord have mercy!" exclaimed a fifth while a sixth chimed in: "Oh lawd. When did that happen!?"

Others, however, were clearly far more transfixed with the second snap of the photo dump - specifically, Robert's left shoulder.

Upon a first glance, it would appear as if he was donning a spider tattoo just on top of his bicep.

However, after zooming in upon further inspection, it's clear that the creepy-crawly was real!

"At first, I thought the spider was a tattoo!" pointed out another fan while a final Instagram user confessed: "Not me thinking the spider on his arm was a tattoo and not a real one!"

Speaking about his decision to team up with Bonds, Robert told the outlet that there was no hesitation with his answer when he got the call.

"It was a pretty immediate yes," he shared.

"I wish I could say I was very suave and cool about the whole thing, but I was like, 'Yes! Let's do it!' Because Bonds in Australia is an absolute icon," the model continued.

"Also, I'm at this point in my life where I'm trying to do as many different and random exciting things, and if it's something that makes me a little bit nervous, that I've never done before and it's a bit of an adrenaline rush? That's what I want to be doing."

Well, it's clear Robert can now add 'underwear model' to his ever-growing list of job titles!
