Video: Yvonne Chaka Chaka tells Mugabe to step down

South Africa and African music legend Yvonne Chaka Chaka tells Zimbabwean President Robert Mugabe that it's time for him step down, rest and write books.

She has an equally stinging message for Ugandan president Yoweri Museveni.

Yvonne Chaka Chaka is an internationally recognised and highly respected South African singer, songwriter, entrepreneur, humanitarian and teacher.

Dubbed the "Princess of Africa" (a name she received after a 1990 tour), Chaka Chaka has been at the forefront of South African popular music for 27 years and has been popular in Zimbabwe, Kenya, Gabon, Sierra Leone and Ivory Coast.

Songs like "I'm Burning Up", "Thank You Mister DJ", "I Cry for Freedom", "Makoti", "Motherland" and the ever-popular "Umqombothi" ("African Beer") ensured Yvonne's stardom.

The song "Umqombothi" was featured in the opening scene of the 2004 movie Hotel Rwanda.
