Motsi’s appointment sparked controversy, with Strictly fans claiming she may show preferential treatment to her sister, Oti, who is a professional dancer on the show.
But a BBC boss has now said that bringing Motsi onto Strictly for 2019 was simply a “no brainer”.
Speaking at the Strictly Come Dancing press launch, Kate Phillips, the BBC controller for entertainment commissioning said: “I get asked a lot about why I picked Motsi, and I just wanted to make it all clear to everyone today.
“When Darcey said it was time for her to bow out, we all were left wondering how we were going to replace such a class act. She’s always going to part of the Strictly family, but we knew we were going to have a real challenge on our hands.
“We spent a long time talking to a lot of talent from the dance world, screening a lot of people. And it’s the honest truth that when we saw Motsi’s screen test, we were all just blown away.”
She continued: “The simple reason why we picked her was because she was just the best person of the job. That screen test combined with her already good judging and dancing credentials made it a no-brainer.
“I cant wait to see her in action, I think it’s actually going to be really brilliant.”
Referring to her time as a judge on Let’s Dance, the German version of Strictly, Mabuse added: “In Germany, we’ve completely gone that way. We’ve had two ladies dance together [singer Lukas Rieger and professional dancer Katja Kalugina, who were paired together in 2019].
“The ratings proved the point that sometimes, if you risk something, it pays off. It might go wrong – but at least you tried. The worst thing you can do is stay on the same spot. I respect traditions but you need to keep developing.”
Strictly Come Dancing launches Saturday at 7.10pm on BBC 1. The competition launches on 21st September.
