Hough will be taking the place of Len Goodman and will be judging alongside familiar faces at the judges' panel, Bruno Tonioli and Carrie Ann Inaba.
Hough danced in five seasons of "Dancing With The Stars" and took home the coveted mirror ball trophy twice. She and partner Olympic gold medal-winning speed skater Apolo Anton Ohno won on season four, and she won again with partner Indianapolis 500 champion Helio Castroneves on season five.
Since departing the show, Hough has focused on her film career. Her credits include "Safe Haven," "Rock of Ages," "Footloose" and "Burlesque." She is slated to star alongside Russell Brand and Octavia Spencer in the upcoming film, "Paradise."
Hough is the sister of current "Dancing With The Stars" professional dancer Derek Hough, who is partnered with Glee actress Amber Riley on season 17.
You can watch "Dancing With The Stars" Mondays at 8 p.m. PT on ABC7.
