Johannesburg- Khanyi Mbau has revealed that the string of steamy Instagram snaps is all a lead up to her 30th birthday celebrations.
Khanyi caused another frenzy when she dropped another snap showing off her bum in a g-string with black lacy lingerie over it.
The snap even has some, erm, seductive sound effects. #Smokinghot
