'DWTS' contestants' adorable old-school quickstep conquered the judges hearts

The star of the 80s comedy "The Facts of Life" charmed the judges of "Dancing With the Stars".

Nancy McKeon, best known for her role as Jo Polniaczek on the NBC sitcom "The Facts of Life" has surprised audiences and the jury of the "Dancing With The Stars" show with a brilliant performance.

The video of the dance routine featuring McKeon and her pro dance partner Val Chmerkovskiy was posted on YouTube by Media Galactic on September 24, 2018, and is quickly going viral.

The duo took to the dance floor and perform a dazzling quickstep to the sound of “It Don't Mean A Thing” by Club des Belugas.

"I was thinking about it, and it’s a challenge. It’s completely outside of anything that I have ever, ever even considered doing, and so, I guess we all have to terrify ourselves every now and again.”
