Julianne Hough is the youngest of Marianne and Bruce's five children. All four girls have mom's golden hair, and Julianne and Derek Hough share their parents love of dance. Yep, the older Houghs met on the dance floor and the singer's grandparents were also dancers. They have style and skill, although to date Julianne is the only one who's gathered singing and acting credits. The youngest of the Utah-born Houghs isn't the only one with national fame however -- Bruce was longtime chairman of the Republican party of Utah.
