Mbau was born and raised by a single mom in Mofolo, Soweto. Her father was in the taxi industry and never at home, according to Mbau.
In 2004 she replaced actress Lindiwe Chibi in the rle of Doobsie on Muvhango, after Chibi was shot in the face by her boyfriend. A year later she was fired from the role, reportedly for spending too much time partying and appearing in the Sunday tabloids.
In 2006 she landed the role of Mbali on Mzansi, but was fired from that show after one season. In 2007 she played the role of Zee in the SABC1 mini-series After 9.
She met journalist-turned millionaire Mandla Mthembu in 2005 and the couple were married in 2006, amidst claims that Mbau was a "gold-digger" after his money. Mthembu had made a fortune when he and a business partner sued Transnet for R80-million over a tender gone wrong - and won.
Mbau claimed she was in love with the older man, but nine months later they were engaged in a bitter divorce dispute, with Mthembu himself alleging that Mbau was after his fortune.
