It's official: Julianne Hough joins “Dancing with the Stars” as 4th judge
“My role is to encourage and be supportive, and to also be candid and honest and try not to beat around the bush, to be too politically correct,” says Hough, whose duties will include judging her brother, Derek. “I want to give critiques so they can improve.
