The siblings' stunning routine, set to "Unsteady" by X Ambassadors, told the painful and personal story of their parents' divorce, as examined through dance. With some amazing set decoration and jaw-dropping choreography, fans were once again reminded of why Julianne and Derek have been DWTS stalwarts all these years.
Speaking with host Tom Bergeron after the amazing dance, Derek opened up about their upcoming tour, and what fans can expect from the dazzling spectacle.
"Our show is a dynamic show. We have everything from emotional to fun to Latin to ballroom, contemporary to hip hop," the six-time DWTS champ shared. "But this piece is sort of a closure piece."
"It's good therapy, it's beautiful," Julianne added. "That's what's so amazing about dance, is being able to express that and have moments like this with our mom in the audience."
Julianne and Derek's mom, Marianne, came to show her support and watched from the audience as her talented children danced their hearts out.
Move -- Beyond -- Live on Tour kicks off April 19 in Akron, Ohio, which means Julianne will be performing live and serving as a DWTS judge at the same time.
"Schedule-wise, I'm going to be sleeping a lot, as much as I can, but I'll be coming back every Monday [to judge]," Julianne recently told ET. "It's going to be fun, I'm excited."
In December, the brother-sister duo sat down with Good Morning America to dish on their upcoming third live tour together, and opened up on how the show is "beyond anything we've done before." Check out the video below to hear more.
