Crikey! Robert Irwin has fooled us all.

A week after teasing fans with news of a big screen debut, the Wildlife Warrior, 22, has revealed the truth behind the dramatic film trailer he shared on socials.

It’s a bloody ad!

Just last week, Irwin took to Instagram with a gripping trailer showing him running through the wilderness. Even without giving much away, it boasted all the elements that guaranteed a night out at the IMAX theatre.

“Something epic is coming. I’m so excited to finally share what I’ve been working on … things are about to get wild,” he captioned the sneak peek at the time.

Now, not only do we know what the I’m A Celebrity … Get Me Out Of Here! co-host and US Dancing With The Stars winner was actually running away from, but also what it was all about.

In a fresh post online, Irwin has outed that the clip is actually an ad for outdoorwear brand, Columbia.

“Robert vs. 100 Crocs: Challenge accepted. The crocs were formidable, but my Omni-Max™ Tellurix shoes were up for the challenge,” he captioned the video

“The cat’s out of the bag … #MAXIMPACT isn’t a movie … yet. Had an absolute blast making this #ad with @columbia1938.”

Argh, ROBERT!

While my initial reaction was sheer disappointment, the ad is indeed clever and fun – everything you’d expect from the loveable larrikin.

Fans online were captivated by the entire spectacle – from the giant inflatable crocodiles chasing him and theatrical narration right down to the closing cameo by his real-life crocodile, Stella.

“This is gold,” one person celebrated.

“This is more adorable than I imagined,” another agreed.

Another added: “I did not see the inflatable crocs coming – incredible lol.”

To be fair, no one did.

The quirky idea for an advertisement even had other brands who have worked with the famous Aussie a tad envious.

Bonds, who famously went viral for stripping Irwin of his khakis for a racy underwear campaign in April last year piped up with their thoughts, saying: “stop this is too good.”

OK fine! But I’m not buying the shoes (… out of protest).
