Bindi Irwin paid tribute to her late father, "The Crocodile Hunter" star Steve Irwin, in a touching Instagram post this weekend.

"You'll be my hero for my entire existence. I love you more than words can describe," the Dancing with the Stars champ captioned a throwback photo of the wildlife conservationist and television personality holding her as a baby.

Irwin, 18, wrote the post in honor of the 10th anniversary of her dad's death.

He was struck in the heart by a stingray barb when he was 44 and died on Sept. 4, 2006.
