Steve Irwin's son will walk sister Bindi Irwin down the aisle when she marries her fiance Chandler Powell - amid increasing speculation of a family feud.
The 21-year-old daughter of the late wildlife expert is set to wed her teenage sweetheart soon, and her 15-year-old brother Robert Irwin will be on hand to accompany her to the alter in Steve's absence.
Excited Bindi revealed she's already picked out her wedding dress as she teased a picture of her lace-covered arm on Twitter .
Showing off a glimpse of the stunning white gown, Bindi wrote: "I said yes to the dress."
The snap shows the raw edge of her delicate lace sleeve set against her enormous vintage diamond engagement ring, which she paired with a translucent pearly nail varnish.
Robert retweeted the image, adding: "Can't wait to walk you down the aisle."
Bindi replied sweetly: "I love you. Thank you for being the best brother."
Their mum Terri is expected to step in for Steve for the traditional father-daughter dance on Bindi's big day, amid claims of a brutal family split.
It was recently revealed that there had been strain within the family since Steve died in 2006 - but a gagging order had prevented them from speaking out about it.
The Daily Mail Australia reported that Steve's father Bob said that he didn't expect to be invited to Bindi's wedding.
His older sister Joy then spoke out, saying she could do so now that a non-disclosure agreement had been lifted.
She said that Steve's wife Terri had begun to distance herself and her kids Bindi and Robert from the rest of Steve's family.
In 2016, her husband Frank was even walked out of Australia Zoo, which he once help to run, by Terri.
Steve was famous for his wildlife TV shows where he would wrestle crocodiles and handle other exotic animals.
He died in 2006 when he was fatally stabbed in the heart by a stringray.
Bindi followed in his footsteps, becoming a wildlife conservationist and TV personality.
