‘Dancing With the Stars’ Season 23 Pro Dancers, Judges & Hosts

Julianne Hough

Previously, Julianne Hough stepped away from DWTS and many thought she would not return. She went on to star as Sandy in the live musical TV production of Grease Live! Now, she is back and has rejoined the judges, which means there probably won't be many guest judges unless Len Goodman sits out an episode or two. (Instagram)
