Mrs Mhinga?

From Wikipedia,
"Chaka Chaka owns a limousine company together with her husband, Dr Mandlalele Mhinga, has her own music label and her own production company. She teaches literacy part time at the University of South Africa, sits on several boards of charitable organisations and NGOs, and serves on the board of the Johannesburg Tourism Company."

Yvonne Chaka Chaka, now that name was much more cooler then Yvonne Mhinga but congrats to her :-)
