Country crooner Kellie Pickler and her pro dance partner Derek Hough wowed the judges of “Dancing with the Stars” with their electrifying jazz routine on Monday night’s episode.

The judges told Pickler they knew she had potential during the first week of performances, but she really set the bar during week two, placing seconds.

The blonde couple, who host Tom Bergeron joked had “zero percent body,” danced to “Lights” by Ellie Goulding. Their set included green lights that glowed as they danced barefoot on the “DWTS” stage.

Since no one gets eliminated on the first week and two weeks scores are combined, the dance scores were out of 60 instead of the usual 30.

Pickler and Hough racked up an impressive 47, just narrowly falling behind Disney star Zendaya and her partner Valentin Chmerkovskiy, who hold a score of 50 out of 60.

"For week two, last week was a spark,” judge Len Goodman said to Pickler and Hough. “This is a fire. Well done.”

Viewers were just as impressed with Pickler’s performance.

“Former 'American Idol' contender-turned-country star Kellie Pickler wowed with a thrilling, futuristic jazz number,” Access Hollywood wrote in their recap of the show.

Pickler revealed she feels more comfortable after her second dance than when she first stepped on the “DWTS” stage.

“People are expecting me to be good, and I don’t know if I am or not,” she said before Monday night’s episode, according to Wetpaint. “I hope people don’t have too high of expectations for me, because I’m not a dancer.”

But when speaking with On the Red Carpet, Pickler said she had found her confidence.

“I mean, last week was the first show – so overwhelming,” she said. “But I don’t know, I'm still running on adrenaline. I'm very happy… I'm very thankful… We gotta bring it next week, big time.”

Hough only had positive things to say about his partner when talking to the website.

“I want her to be sensational because she has the capacity to be fantastic,” he said of Pickler.

Watch “DWTS” Tuesday night on ABC at 8 p.m. EDT to see which couple gets sent home.
