Last night, Australian animal conservationist Bindi Irwin and her partner, Derek Hough, won big on the dance floor, taking home the Mirrorball Trophy on Season 21 of Dancing With the Stars. Good job, lil' lady!

The 17-year-old has been a front-runner all season and had to battle Backstreet Boys Nick Carter in the finale. We guess Backstreet's not back!

After the win, the teen, whose father is late wildlife expert Steve Irwin, took to Twitter to thank her fans for their support, writing, "I am speechless. I can't tell you how much love I have for all of your support throughout this beautiful journey."

Meanwhile, it was also a big night for Kim Zolciak. The reality star left the show prematurely due to a health condition but came back in full force last night. The mother of six suffered after a mini stroke and underwent heart surgery recently, but the 37-year-old was back on the show to perform her I Dream of Jeannie routine last night. Afterwards, the busty blonde posted an emotional video about being grateful for the opportunity.

Thank you GOD!!!! ❤️
