Bindi Irwin and her past Dancing With the Stars partner, Derek Hough, are such adorable friends!
Derek, 31, took to Instagram on Monday, Nov. 14 to give Bindi, 18, a sweet shoutout in honor of Australia's Steve Irwin Day.
"Since it's Nov. 15 in Australia, I wanted to wish everyone a wonderful Steve Irwin Day. I was always a fan of his passion and love for the world. His legacy lives on. It was such an honor and privilege to get to know and work with his beautiful daughter. Such a special soul," the pro dancer began.

"Choreographing and creating with her, helping to tell her story will always be a highlight in my career. This image was taken at the end of our final dance which was a tribute to her super hero, her dad, Steve Irwin," Derek captioned a candid pic of Bindi.
Derek and Bindi previously won Season 21 of DWTS together in November 2015. The conservationist lost her dad, Steve, in September 2006 after he was fatally stabbed by a stingray while snorkeling in Australia's Great Barrier Reef. He was 44-years-old.
