Big Brother Mzansi expells Siyanda Ngwenya known as Adams after being accused of raping a female housemate while she was asleep after a drunken night of partying in the house in Johannesburg.

The pair were last seen on TV kissing and cuddling in bed before the cameras moved away.

Ngwenya reportedly boasted to housemates the next day that he had sex with the woman.

However, the alleged victim is said to have been shocked by the claims and reportedly told female contestants that she did not consent to having sex.

Expelled: Siyanda Ngwenya (pictured), a contestant on the South African version of Big Brother, has been accused of 'sexual misconduct' with a female housemate after drunken night of partying on the show

In a statement last night, Mzansi Magic, the channel which airs Big Brother, said: ‘At this stage, it is not exactly clear what transpired between (the woman) and Adams.

‘Having suspected that there may have been an incident of sexual misconduct, Mzansi Magic acted by removing both individuals from the house.’

The company said the alleged victim had been ‘removed for her own well-being’ and that both contestants were receiving counseling.

It is not yet known whether police have been called into investigate the alleged incident, which took place on Saturday night when alcohol is made freely available to the housemates.
