Dudu Zuma, President Jacob Zuma's daughter, has launched herself into Jozi's social circles and socialites are more than happy to welcome her.

The A-listers of Jozi were there and so was controversial ANCYL president Julius Malema.

Among the celebrities who attended were Khanyi Mbau, DJ Mahoota, Andile Ncube, Andile Galeshiwe, Somizi Mhlongo, Lindelani Mkhize and former Miss South Africa Tansy Coetzee.

Model Miriam Ngomani was clad in a red coat and black leggings.
