Zahara said she was proud of their growth so far and wanted to sign them up.
"They must relax. If they don't win Idols SA, I am here. They will still tell their story. They will still sing. I will take them under my wing. I want to sign them. They are brilliant, they can really sing. I want them on my record label."
The musician said that not everyone could win the show and she didn't want the twins' talent to go to waste.
"They can sing. They are unique but there is so much talent. I know that not everyone can win. In my eyes they are already going to win, but if they don't, I am here."
