‘Dancing With The Stars’ 2015 Spoilers: Julianne Hough To Dance During Week 9; Who Will She Perform With?

Julianne Hough is leaving her post at the judges' table to shake it out on the ballroom floor during Week 9 of “Dancing With the Stars.” That’s right, the former “DWTS” pro is returning to her rumba-ing roots as Season 20 of the hit ABC competition winds down.

According to reports, ABC will add a twist to the 2015 competition as each judge participates in the Week 9 semifinals. “For the first time ever, each of our judges will coach one couple for a dance -- pick their song, dance style and creative. You might even see the judge in the performance!” the network teased on Instagram. The “Judge's Choice” dance will then be critiqued by the three remaining judges and will count toward the participants' overall scores.

Julianne will be the one judge to partake in a performance, turning her cousin Riker Lynch and his partner Allison Holker’s duet into a trio. The three will take on the Argentine tango during Monday night’s installment. And according to Julianne, their “grounded” and “high-energy” performance will blow the other three judges away!

“Len [Goodman], Bruno [Tonioli] and Carrie Ann [Inaba] better watch out!” the short-haired stunner warned her competition in a promo video for the episode.

The Season 4 winner explained during the behind-the-scenes clip that although she loves Allison’s choreography, she thinks she’ll be able to enhance the routine with her additional flare. “We’re going to really blend well together because she’s going to have her own style -- and I’m not going to be able to touch that. But I’m also going to bring a little bit of mine, which is a lot more classical," Julianne said.

While Julianne works with Riker and Allison, Len will team up with Nastia Liukin and Derek Hough, Bruno will work with Rumer Willis and Val Chmerkovskiy, and Carrie Ann will help Noah Galloway and Sharna Burgess bring the heat to the Season 20 semifinals.
