Robert Irwin has revealed that he will walk his sister Bindi down the aisle on her wedding day.
Bindi got engaged to long-time boyfriend Chandler Powell on her 21st birthday in July, and shared a sneak peak of her bridal dress on Twitter on Sunday.
Replying to the post, younger brother Robert, 15, said: "Can't wait to walk you down the aisle."

Chandler proposed to Bindi at Australia Zoo, which was founded by Steve's parents and co-owned by Steve and his wife Terri. The wedding itself will also be held at the zoo next year - and naturally, animals will be at the heart of it.
Bindi said that having Robert walk her down the aisle is what Steve would have wanted.
Speaking to E! News, she said: "It's so important to include the people that can't be there with you, so on the day, I know that Robert is absolutely gonna walk me down the aisle and I think that's what would make dad happiest."
Bindi also revealed that she is planning on having her own 'wildlife warriors' with Chandler - though they've got a big wedding to sort out first and foremost.
She said: "One day we'll have a family. One day we'll have our own little wildlife warriors, but not yet."
