Robert Irwin has shared the first picture of him cradling his newborn niece, after older sister Bindi welcomed her into the world yesterday afternoon.
Holding his niece in his arms, Robert wrote a touching message to his sister and brother-in-law in the post's caption:
"Let the uncle adventures begin! Love you so much, Grace.
"This little one picked the two best parents in the entire world. The most incredible, caring and strong Mum... and the funnest, coolest and kindest Dad. Love you three so much - I can’t wait for this exciting journey ahead!"
Robert, who is now 17 years old can be seen smiling with pride in the snap, which has since amassed over 500,000 likes in just a few hours.
And it cannot be denied, the teenager is the spitting image of his late father, as you can see from the image below that was shared to Twitter two years ago by his mom, Terri.
In the pic, Steve can be seen beaming the same proud smile as he admired a baby Robert.
Adored by their fans, Robert's post was flooded with messages of congratulations, and with Steve in people's thoughts, many took the time to comment how proud the late Crocodile Hunter would be of his family:

"Grace Warrior Irwin Powell. Our graceful warrior is the most beautiful light. Grace is named after my great-grandmother, and relatives in Chandler’s family dating back to the 1700s. Her middle names, Warrior Irwin, are a tribute to my dad and his legacy as the most incredible Wildlife Warrior. Her last name is Powell and she already has such a kind soul just like her dad.
