Zoleka Mandela's daughter, Zenani died at the age of 13, in a car accident in 2010.
Zenani died two days after her birthday, in a car accident, while on her way home from the World Cup concert in Soweto. Zoleka has previously spoken openly about her battle with drug and alcohol addiction, and at the time of her daughter's death, she was recovering in hospital following an attempted suicide attempt.
Following the tragic incident, Zoleka, has been at the forefront of worldwide campaigns advocating for road safety.
Sharing a slideshow of photos of her daughter, she wrote: "Happy 23rd birthday to my daughter in Heaven. [sic]"
The emotional tribute is set to Brandy's Missing You, and one photo shows Zenani in an embrace with her great grandfather, former president Nelson Mandela.
In recent years, Zoleka has spoken about her on-going battles with depression but had made positive steps on her road to recovery.
Despite Zoleka's troubles in the past, in March she part ways with her husband, and she has since been working on her health, and fitness.
