Bindi Irwin has wowed audiences on the US version of “Dancing with the Stars” ("DWTS") Season 21 and it looks like she will continue to do so all the way to the finals. This week’s "DWTS" semi finals saw Bindi pulling off stunning dance performances featuring the music of Major Lazer & DJ Snake featuring MØ, Nathan Lanier and Sia.

Bindi and her "DWTS" 2015 partner Derek Hough showed off their salsa moves while dancing to Sia's "You're Never Fully Dressed Without a Smile." Despite their lively performance, which got mostly positive reviews, they didn’t manage to secure a perfect score due to a lack of hip movement. The duo received a total of 27 points (9, 9, 9) for a lack of “side-to-side salsa action."

Bindi's brother Robert and mum Terri Irwin still kept praising the 17-year-old Australian presenter, conservationist and actress.

"I think she's definitely growing up and Derek has a lot to do with that journey and it's been just beautiful. I'm so proud of her," Terri told "DWTS" host Erin Andrews.

Robert was ecstatic after his sister's performance.

“I think she's absolutely amazing, I'm so proud of her and you crushed it – that was that awesome."

For her jaw-dropping jazz performance with Hough and dancer/choreographer Mark Ballas, Bindi wrapped a rope with a light bulb around her neck and danced in a box frame.

Irwin, Ballas and Hough performed with the song "Resolve" by Nathan Lanier as their background music. They earned a perfect score of 30 (10, 10, 10) from "DWTS" 21 judges Julianne Hough, Carrie Ann Inaba and Bruno Tonioli.

But Bindi was still not satisfied with her scores and she stepped up the action like never before by defeating “Backstreet Boys” singer Nick Carter and partner Sharna Burgess in a samba dance-off. They danced to the song "Lean On" by Major Lazer & DJ Snake featuring MØ. Bindi and Derek received three points.

After the shocking exit of fellow "Dancing with the Stars" 2015 contestant Tamar Braxton due to pulmonary embolism (blood clots that travel in the lungs), no one got eliminated. The "DWTS" 2015 semi-final results confirm that the final contestants are Bindi Irwin and Derek Hough, Carlos PenaVega and Witney Carson, Nick Carter and Sharna Burgess, and Alek Skarlatos and Lindsay Arnold.
