Hough's formal training began at the Center Stage Performing Arts Studio in Orem where she danced with Josh Murillo, among others, in Latin Ballroom. She began dancing competitively at nine. When she was 10, Julianne's parents, who were divorcing, sent Julianne and her brother Derek to London to live and study with their coaches, Corky and Shirley Ballas. The Ballases tutored the Houghs alongside their own son, Mark. At the Italia Conti Academy of Theatre Arts Hough and her brother received training in song, theatre, gymnastics and many forms of dance, including jazz, ballet, and tap. When Hough was 12, the three children formed their own pop music trio 2B1G ("2 Boys, 1 Girl"). They performed at dance competitions in the UK and the U. S. , and showcased in a UK television show. At 15, Hough became the youngest dancer, and only American, to win both Junior World Latin Champion and International Latin Youth Champion at the Blackpool Dance Festival. She left London that year, after having been "abused, mentally, physically, everything," she said, a situation that escalated "when I started hitting puberty, when I started becoming a woman and stopped being a little girl. . . . I was told if I ever went back to the United States, three things were going to happen. One: I was going to amount to nothing. Two: I was going to work at Whataburger. And three: I was going to end up a slut. So, it was like, I can't go back. I have to be this person. " After returning to the U. S. , she attended the Las Vegas Academy and Alta High School.
