"Duck Dynasty's" star Sadie Robertson continues to wow judges with her weekly performances in "Dancing With the Stars" season 19, making her one of the favorite contenders to vie for the Mirror Ball on the finals night.

Just last week, Sadie received astounding scores from the judges during the non-elimination Switch Up episode wherein the pairs had to switch partners. Her Charleston performance with veteran pro Derek Hough, to the tune of "Crazy Stupid Love" from Cheryl Cole feat Tinie Tempah, earned her four 9s, and she received several remarkable comments from the judges.

Judge Julianne Hough, who also happens to be her partner's sister, pointed out that she consistently shows a different side of her in her performances every week even if she had to work with another partner instead of Mark Ballas.  Guest judge Jessie J claimed that Sadie's routine was "really clean." Moreover, Carrie Ann Inaba and Bruno Tonioli said that Sadie and Derek's number was "magnificent" and "spot on."

For the upcoming episode, the 17-year-old reality show star will return with her original partner Mark to dance the Rumba. Mark gushed about his excitement for the return of his and Sadie's partnership in his article posted on Hollywood.com.

He said, "I'm looking forward to having Sadie back and dancing the Rumba next week. It's a sensual, romantic dance, and I want to make sure that it's age-appropriate while still telling the story as beautifully as she does."

Also, Mark said that they are preparing hard for the next celebrity judge.

The pro dancer shared, "It's also Pitbull week! I'm a big Pitbull fan, so it'll be awesome to have him come on the show, perform, and judge. I'm really looking forward to it!"

Will Sadie live up to expectations in the next episode of "DWTS"?

"Dancing with the Stars"  season 19 week 6 will be aired Monday, Oct. 20, on ABC.
