Bindi also revealed to Entertainment Tonight that it will be Robert who will walk her down the aisle:
"I think that for me, it’ll be really important that Robert walks me down the aisle, that’s something that I really want to do."
"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," Bindi added.
"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."
