When Hough was 12, his divorcing parents sent him to London to live and study with dance coaches Corky and Shirley Ballas.
Hough's sister Julianne joined him in London several months later.
All of his grandparents were dancers, and his parents met while on a ballroom dancing team in college in Idaho.
He is the second cousin of musicians Riker, Rydel, Rocky, and Ross Lynch from R5, their maternal grandmothers are sisters.
Originally intending to stay for a year, Hough remained in London for ten years.
(Julianne returned after five years.) The Ballases helped tutor the two Hough children alongside their own son, Mark Ballas, schooling them at the Italia Conti Academy of Theatre Arts.
As of 2014, he has held a recurring acting role on ABC's musical-drama, Nashville.
