This past week, legendary singer Stevie Wonder performed on Dancing With The Stars: Juniors while his 13 year-old son Mandla Morris danced with partner Brightyn Brems. The crowd immediately went wild as the young dancers stole the show!

Wonder sang “Isn’t She Lovely” in the background while Mandla and Brightyn performed an amazing foxtrot ballroom routine. This is one of the hardest kinds of dances to perform, but the two kids managed to perform it effortlessly!

The judges made it clear that they were amazed by the entire performance.

“Well first it is so incredible to have the amazing Stevie Wonder performing tonight, I know if I had to do a performance with my dad on Dancing With The Stars it would not have looked like that,” said judge Adam Rippon. “You were so good, this is probably one of your best dances.”

Judge Val Chmerkovsky agreed that the performance was “incredible,” prompting Wonder, who is blind, to joke, “It looked good to me!”

Judge Mandy Moore, who can be difficult to please, also had nothing but good things to say about the performance.

“I was watching a beautiful couple twirling around the dance floor, you will remember this moment forever,” she said.

Mandla is the seventh of Wonder’s nine children, and in a backstage interview, the singer talked about how happy he was that his son chose his song to perform to.

“He made a great choice, I am very happy he did and very thankful,” Wonder said.
