Robert Irwin says it was an honour to walk his sister Bindi down the aisle as she married the "perfect" Chandler Powell.
Steve Irwin's kids showed a united front after suggestions a family feud was tearing them apart.
It was reported in September that members of their clan have fallen out and no longer speak 13 years after his death.
The once close-knit family changed after he was killed by a stingray in 2006, said the Crocodile Hunter's sister Joy Muscillo.
Bindi's big day was a huge thing for Robert, 15, as his 21-year-old sister said 'I do' in July.
Proud Robert told PEOPLE: "I was just so so stoked.
"I was so excited and really honoured for her to ask me to walk her down the aisle.
"I think it's going to be such a wonderful day, such a great celebration.
"Chandler is absolutely perfect. I can’t fault him, he’s awesome."
Bindi has previously said to Entertainment Tonight: "It’ll be really important that Robert walks me down the aisle.
"I’m always so grateful that Robert is there, and he has been such a big part of my life and he’s always stepped up and been the one to give me a hug when I need it and encourage me forward in life.
"So he will definitely be the one to walk me down the aisle when the time comes, and I think that will make it really special."
The comments come as Steve Irwin's sister revealed last month that the Irwin family don't speak 13 years after the Crocodile Hunter's death.
Joy told Daily Mail Australia that Steve's wife Terri and their children, Robert and Bindi, estranged themselves after his tragic death.
The animal expert's father Bob Irwin is also said to have become a recluse since his son was killed in 2006.
