Now there's a massive debate on Twitter as to who had the worst performance between her and Fergie's frightening attempt in 2018. The one thing I will say is this... Chaka is a legend and has always been known for her soaring vocal ability. She is 66-years-old and can still sing most of the younger generation out of the water. Leave her alone, please. She was just having an off day and I will leave it at that.
