Bindi expressed that she really wants her younger brother, Robert, to walk her down the aisle on her wedding day. "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 told ET. "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. And I think that's what dad would have wanted as well."
