It may only be the second week of "Dancing With The Stars," but Bindi Irwin and her partner Derek Hough already have a pretty good shot at bringing home the Mirror Ball trophy. The two have scored the highest on both nights so far, and with Hough's previous winning record, it's likely we'll be seeing him in the finale once again.

Last week, Bindi honored her father, the late Steve Irwin, and her passion for animals with a safari-themed jive to Elton John's "Crocodile Rock," khakis and all. Last night, she showed a side of her we've never seen while dancing the tango to AC/DC's "You Shook Me All Night Long." Stunning in a black and silver gown, Irwin really nailed the tango and she, and Hough added their own rocker twist to it.

"So proud of my BEAUTIFUL BINDI!" Hough captioned a photo of the two with all the ways to vote for them following their dance. "Her improvement has been extraordinary in such a short amount of time. Who would have thought. @bindisueirwin #rockqueen #wildlifewarrior."

Since this week was all about picking a song and dance that reminded the stars of their hometown, people couldn't help but wonder why this animal-loving, young Australian picked a heavy metal song.

Turns out, it was a favorite of her father's. "That's what my mom and dad especially, would listen to," she said in a pre-recorded segment about her choice of song. "I was so little and so happy."

When asked how performing to it made her feel, she said, "You know, it felt really really good. I remember when I was little dancing to that song with dad, and it means everything to me. So I'm glad I could be here tonight." The camera then cut to her mom and little brother, who got emotional as Bindi spoke about her dad.

It was obvious that Irwin was moved by the performance as she remembered her father. "At the very end it hit me because of the meaning behind the song. It was so great because there's so many memories attached," she told People following the dance, adding, "Sometimes you just need a moment. I think I was just so excited because the song means so much to me. That just hit me. There are so many memories attached to that song."

The song not only reminds her of her father but of the times they spent dancing to it together at the Australian Zoo. "It reminds me of home," she told E! News. "Dad listened to AC/DC and all of this rock music. And for me, it's really not so much the song as it is the feeling and the memories that it brings back and I love it. I love it."

Bindi posted a gorgeous black-and-white shot of the two dancing last night with a heartwarming caption. "Last night ROCKED! So incredibly happy to share our family's love of #ACDC with you," she wrote. "It meant the world. I have a million memories with this music, spending time with my Dad, Mum and little brother. I can't wait for another amazing night. @derekhough has chosen the most moving song that will truly touch you. Love and light always."

On tonight's show, the hometown theme continues, only this time, they'll be dancing to a song that reminds Hough of where he grew up. Hough picked "Only a Man" by Jonny Lang, which is a much more mellow and emotional song, so it will be exciting to see the two slow it down for the first time as they dance the waltz. Bindi will even be making a drastic change from her rocker chic outfit last night to an elegant princess tonight, according to E! News. Irwin is set to wear a beautiful pink gown with intricate lace and jeweled details, and there's no question the 17-year-old star will look absolutely stunning.

See Bindi stun in the pink gown tonight on ABC!
