"Duck Dynasty" castmember Sadie Roberton shared a photo of herself and professional dancer Mark Ballas practicing in a dance studio on Thursday.

The 17-year-old will appear on season 19 of hit reality show "Dancing with the Stars," and is ready for the competition to begin.

"Let's geauxxxxxxx dancing with the stars season 19," she captioned the photo, using a Cajun-inspired spelling of the word "go."

The line-up of "Dancing with the Stars" was announced on "Good Morning America" on Thursday. In addition to Robertson, most of the other previously leaked contestants were confirmed: "Pretty Little Liars" star Janel Parrish, Olympic athlete Lolo Jones, actor Antonio Sabato Jr., iconic designer Betsey Johnson, YouTube star Bethany Mota, and former UFC champion Randy Couture.

Six other contestants will compete this season: Alfonso Ribeiro, best known as Carlton from the 90s sitcom "The Fresh Prince of Bel-Air," actress Lea Thompson, "Mean Girls" actor Jonathan Bennett, NASCAR champion Michael Waltrip, comedian and actor Tommy Chong, and author and media personality Tavis Smiley.

Sadie is a budding fashion designer and YouTube personality, and maintains that she will not compromise her faith as her popularity grows.

"I think people use fame as an excuse to lose their faith," she told FOX411 in March. "Faith is obviously my number one priority and I think you need to put God at the top of everything you do.

"When we began 'Duck Dynasty,' we weren't starting it for fame," she continued. "We started it to get the message of God out there."

The new and returning professional dancers are Mark Ballas, Cheryl Burke, Valentin Chmerkovskiy, Derek Hough, Tony Dovolani, Peta Murgatroyd, Karina Smirnoff, Sharna Burgess, Artem Chigvintsev, Allison Holker, Keo Motsepe, Emma Slater, and Emma Slater.

Professional dancer Julianne Hough will join Len Goodman, Carrie Ann Inaba, and Bruno Tonioli at the judge's table this season, which begins Sept. 15 on ABC.
