Robert Irwin first captured hearts as the energetic, spitting image of his father, the late Crocodile Hunter Steve Irwin. Robert made several appearances on The Tonight Show with Jimmy Fallon, where he brought animal "guests" along with him, and his family's reality show, Crikey! It's The Irwins.
The Australian animal expert and photographer turned 21 in December, and he's officially all grown up. He's clearly crushing his modeling career, having recently appeared in a shirtless underwear campaign for Bonds. In the photos, Robert poses in his Bonds underwear, shows off his rock-solid six-pack, and holds various snakes. The star shared exactly how he stays in shape, and we're all ears!
He's at a Point in His Life Where He Wants To Do "Different and Random Exciting Things"
Robert shared why he was excited to participate in the Bond campaign.
He said, "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. 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."
Robert posted on Instagram, "I've been wearing @Bondsaus my whole life – proud to celebrate Australia's most iconic animals, and the most iconic underwear!"
