All in the family! Get to know these stars' brothers and sisters
Julianne and Derek Hough
After their parents divorced, dancer Julianne moved from Utah to London with Derek to study at London's Italia Conti Academy of the Arts. Years later, both Hough siblings hit it big on ABC's Dancing With the Stars. Julianne—who released a country album in 2008 and starred in Safe Haven in 2013—won twice, with partners Apolo Ohno and Helio Castroneves, and Derek took home the mirrorball trophy four times: With Brooke Burke, Nicole Scherzinger, Jennifer Grey and Kellie Pickler.
