The full cast will be revealed during a live announcement on Good Morning America on March 8.
It was revealed this week that Derek Hough would not be returning next season after the dancing pro opened up to ET about his sister, Julianne, being out as a judge.
"I think she did three great seasons, and it's time for her to go," Hough explained in February. "She's got great things on the horizon, and she's doing great things. Len [Goodman]'s coming back, and so, you know, I think four judges feels a little redundant anyways, so I think it's the right thing to do."
