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."
