Robert Irwin has been capturing hearts around the world thanks to his good nature and sweet personality. The 21-year-old is currently competing on the American version of Dancing With the Stars, and has been lucky enough to share the experience with his mum, Terri and his sister, Bindi, who have moved with him to the US to support him.

Also joining Robert in the States is Bindi’s husband, Chandler Powell, and their daughter, Grace, four, who is probably her uncle’s biggest fan. The pair share a very sweet bond, which was solidified this Halloween when they dressed up as Cinderella and Prince Charming.

Robert showcased his newfound dancing skills on social media by sharing a video of him dancing with his niece.

“Promised Cinderella a dance for Halloween,” he wrote.

“I’m really happy these dancing skills are coming in handy.”

“You made Grace’s dream come true,” Terri said.

Bindi also shared a heartfelt message to her younger brother.

“Thank you for being such a wonderful uncle and brother and friend. We love you so much,” she said.

“You just made Grace’s entire year.”

One fan joked that everyone was “collectively falling in love with Robert” after seeing the video (and perhaps after watching him dance shirtless?).

“Stop it, this is the cutest thing ever,” another said.

“He really is the total package,” a third added. “He’s going to make someone really happy!”

“How many times a week are you going to break the internet?” joked another.

It comes as Robert also paid tribute to his father, Steve Irwin, in a sweet post about keeping the Crocodile Hunter’s legacy alive.

The 21-year-old shared a sweet snap of himself and his dad holding a baby crocodile, along with some more recent photos of himself walking in his dad’s footsteps.

“This is where my love and fascination of crocodiles began… with my dad,” Robert wrote on Instagram.

“He taught us all to appreciate all animals, even the less cuddly ones.

“These animals play a vital role in the ecosystem, and they are in need of our protection as a keystone species.

“Crocodile conservation is at the core of our work together, to keep my dad’s legacy alive.”

In one photo, Robert is shown holding a rope around a giant croc’s mouth, and in another, he holds a smaller baby croc.

“I’m so proud of you for continuing your dad’s mission and message of wildlife conservation,” his mum, Terri Irwin, commented on the post.

“Crocodiles are among our most important apex predators, and your research, rescue, and education work with these saurians is so very important.”

One fan commented that they almost got Robert and Steve confused in one of the photos.

“My goodness that third photo I thought was Steve for a moment.. he is the perfect combination of both parents,” they said.

“Steve was a huge loss to humanity but you are filling the void,” another said.

“Your dad taught that lesson so well,” wrote a third.

“It doesn’t have to be cuddly to be amazing.

“I will never think of crocodiles as ‘gorgeous’ and ‘a beauty’, as Steve did, but I do think they are fascinating and amazing creatures.”

It comes after Robert recently broke down after speaking about the message he received from Steve from beyond the grave.

The 21-year-old recalled seeing a video of his father speaking about his children and the hope he had that they would continue his passion for Australia Zoo.

“For me watching that, it’s like he gave me this gift — it’s there, it’s material, it’s in writing,” Robert said on the podcast The Viall Files.

“I’m watching him looking through the camera and telling me ‘I’m not always gonna be here’.”

Robert’s voice cracked as he recalled that his father was telling him that he was “creating something that you can continue and that’s what I want you to do”.

“That’s what I get to do now, and it fills me with a lot of pride,” Robert said.

Steve died in September 2006 at the age of 44 from an injury caused by a stingray while filming an underwater documentary in the Great Barrier Reef.

Robert was just two years old. His sister Bindi was eight, and the pair were homeschooled on the Australia Zoo site.
