"I'm so excited to be back with my Dancing with the Stars family again on a regular basis. I've always aspired to be an all-around entertainer, whether I'm acting, dancing or singing, and I'm thrilled for this opportunity that will allow me to continue all of those pursuits," she said in a statement Thursday, confirming her new gig. "Derek and I just finished our Move Live on Tour, which reminded me how much I miss the interaction with the dance fans that have been so supportive of me in my career. I am warming up the paddles and the sass, and I’m ready to have fun in this new role."
The 12 professional dancers competing in the hit ABC show's 19th season are Mark Ballas, Cheryl Burke, Witney Carson, Artem Chigvintsev, Valentin Chmerkovskiy, Tony Dovolani, Allison Holker, Derek Hough, Keo Motsepe, Peta Murgatroyd, Emma Slater and Karina Smirnoff.
The celebrity competitors they’ll be partnered with will be announced live on Good Morning America on September 4.
