TV personality Khanyi Mbau has hit back at harmful reports suggesting her teenage daughter is pregnant, labelling the nasty rumours as "cyberbullying".

"..she [Khanyi Mbau] didn't only shiy' ndoda eDubai but she also left her child alone in a rented apartment and now the results are coming out [sic]," reported an entertainment blog Thursday.

The article claimed that social media users "are convinced" Khanyi's 15-year-old daughter is pregnant following a video posted by Lasizwe Dambuza on Twitter, which showed her wearing a "baggy shirt" and trying to "find a position that won't show her tummy well".

In an Instagram post, the actor said that although she typically does not "entertain gossip", she will not allow her daughter to be "victimised and abused"
