‘DWTS': Watch JoJo Siwa and Jenna Johnson Nab First Perfect Score of the Season With ‘Grease’ Dance (Video)

JoJo Siwa and Jenna Johnson picked up the first perfect score of the season on “Dancing With The Stars” Monday night, nailing their foxtrot on “Grease” night.

The two women danced to “Look At Me, I’m Sandra Dee (Reprise),” with Siwa taking on the role of Sandy — pre-transformation, of course — and Johnson playing Frenchie. The pair even got a chance to speak with the original Frenchie from the 1978 movie musical, Didi Conn, prior to their performance.

“How come you guys don’t look sweaty or anything?” Conn joked as she video chatted with the women during rehearsals. All joking aside, Conn was excited to see the two contestants honor the “Grease” characters.

“Frenchie wants people to feel good, inside and outside. So right away, she’s protective of [Sandy],” Conn explained, with Johnson noting that she feels her relationship with Siwa is similar. “You know, Olivia [Newton-John] and I are still friends to this day, but it’s beautiful that you have that special friendship!” Conn added.

When Siwa and Johnson finished the number and lined up to get their scores, the judges were all blown away. Longtime judge Len Goodman went first, giving the two women the most sincere praises.

“You affected my brain with the quality of the technique, you affected my heart with the artistry that you produced,” Goodman said. “It was superb.”

Derek Hough commended the two on their “power and grace” and called the number “absolutely pristine,” while Bruno Tonioli admitted he was “still shivering” after the dance was over.

“You guys leave me nothing to say at this point except, I can just say that that was perfection,” Carrie Ann Inaba chimed in.

And with that “perfection” came the first perfect score of the season, as the four judges gave JoJo Siwa and Jenna Johnson 10s across the board (prompting Siwa to fall to the floor in excitement).
