Julianne and Derek Hough Have a Thanksgiving Dance War You Need to Watch

Julianne and Derek Hough gave us a glimpse into their family festivities on Thursday by posting a series of Instagram videos showing off their annual "dance war." Besides being brother and sister, the two are widely known for their ridiculously impressive dance moves — and their collective judging and choreography work on Dancing With the Stars — and made sure to show them off alongside their sisters, nieces, and nephews. While most of the videos are set to the tune of Pitbull's "Fireball," there is a very nice rendition of the Frozen hit "Let It Go," as sung by Derek and Julianne's young relative. Scroll through to watch all the videos now, and see how other celebrities are spending their Thanksgiving weekend.
