Julianne Hough returned to Dancing with the Stars Monday night when she sat on the judges’ panel of the show’s “Switch Up” episode.

Hough joined Len Goodman, Carrie Ann Inaba, and Bruno Tonioli to judge switched up dancing pairs.

Hough caused ripples on DWTS last season when she appeared as a guest judge in week four. In her critique of pro dancer Mark Ballas and his partner Christina Milian, Hough cautioned Milian against remaining in the background, saying that Ballas can tend to overshadow his partners.

Ballas, who had choreographed the dance, was reportedly miffed by Hough’s critique.

Some fans speculated that Hough’s comments had contributed to Milian’s elimination the following week.

“You can always count on me to tell the truth,” Hough said prior to Monday night’s show. “It’s all about making comments that whoever the dancer or celebrity is, they can be better for next week. There’s never any harsh criticism just because I want to be harsh, that’s not my nature or my character.”

Hough admitted that sometimes critiques can come off as harsher than the judge intends.

“You go in trying to give constructive criticism, but when the nerves get to you, you sometimes put your foot in your mouth, which I have done in the past. So this is my do-over,” she said, admitting that when it came to critiquing Ballas and Milian, she “could have probably said it a little differently.”

Hough is no stranger to the DWTS contestant perspective, having been one herself in past seasons. She and Olympic speed skater Apolo Ohno won season four. She followed that up with a season five win, partnering with Brazilian race car driver Hélio Castroneves. Hough competed in seasons six through eight but was unable to achieve another win.

Hough and her brother Derek are currently preparing for their 42-city Move Live on Tour show. Derek is a professional dancer and DWTS alum. He’s won five seasons of the show and is currently partnered with paralympic snowboarder Amy Purdy.
