Get Excited, Derek and Julianne Hough Are Performing Together During the DWTS Finale!

Exclusive: The fan-favorite judge and dancer will dance during a Sia performance on the Tuesday, May 19 finale

 Prepare for double the Hough on the dance floor!

Derek and Julianne Hough are set to perform together during Dancing With the Stars' season 20 finale on Tuesday, E! News has exclusively learned. And it gets even better.

The fan favorite DWTS pro and judge will be dancing during a special performance by Sia, who will be performing "Elastic Heart." (Anyone else hoping for another secret Kristen Wiig cameo?!)

Choreographing the siblings' routine? Derek, who funnily enough, performed Sia's "Chandelier" when he went up against Julianne on Spike's Lip Sync Battle!

This will be the second week in a row fans have been treated to a performance by Julianne, a former pro, who performed in a routine with her cousin, finalist Riker Lynch, and his partner, Allison Holker. (Rumer Willis and Noah Galloway also made it to the finals.)

Though he suffered a pretty serious injury earlier in the season before being eliminated in the semi-finals with celeb partner Nastia Liukin, Derek is still set to headline the Move Live Tour with Julianne this summer. 

"It's going to be an incredible show," Derek told E! News recently. "I'm going to be at full strength really soon. I've cut my recovery in time in half!"

DWTS airs Monday at 8 p.m. on ABC, and Tuesday at 9 p.m. on ABC.
