Bindi Irwin, who with professional partner Derek Hough won Season 21 of "Dancing With the Stars" Tuesday night, said the legacy of her father had inspired her.

"Honestly, I hope that he'd be proud of me. And I hope that I am able to carry on in his footsteps and make sure that his legacy lives on."
