Of course, the most well-known sibling of Julianne Hough's is her brother, Derek Hough. The two of them made their mark in the dancing world through "Dancing With The Stars" and have both grown to so many other things since being on the show. "Oh my gosh we literally can't get rid of each other," Julianne told E! News in 2018 about her brother, Derek. "The other day I was telling him that I don't feel right. He was like, 'Go dance. Go write a song. Go do something.' He knows me so well." And despite seeming like twins, they are about three years apart — and the two have three sisters that not everyone might know about.

The Hough siblings consist of Sharee, Marabeth, and Katherine — alongside Derek and Julianne. The Las Vegas Review-Journal reported in 2018 that after the Hough parents got divorced, their mother, Marriann, married financial consultant Aaron Nelson in 1998. With the five Hough children and Nelson's own four children, they had a massive blended family. Bruce Hough, their father, got remarried in 2000 to Debra Hough.

While all of the Hough siblings have professional and/or personal social media profiles, they aren't photographed together very often. So fans love it when they do post together, as Hello Magazine shared. Julianne shared a "rare" post in 2021 that had fans writing things like, "Everyone in the Hough family is beautiful."
