Bindi Irwin says one special person in particular would be proud of her brother.
The conservationist, 21, recently shared a touching note on Instagram about how much her father, the legendary Steve Irwin, who died tragically in September 2006 from a stingray attack, would appreciate his son's presence.
"Dad, You would be so incredibly proud of Robert," she wrote about her brother.
"He has been such an amazing support during this beautiful new life chapter," she continued. "I know you’d be beaming with pride when the time comes that he walks me down the aisle."

Bindi announced her engagement to Chandler Powell in late July, after her fiancé proposed on her birthday.
"Chandler, close to 6 years ago I fell in love with you and every day since has been a whirlwind of adventure and true happiness," she wrote.
