SELLY AND NATASHA HAVE BEEN EVICTED IN BIG BROTHER AFRICA THE CHASE

Though Selly has been evicted today in Big Brother Africa "The Chase" she said something from her heart after being asked 

"You know I real love each other in the chase as my housemates, but I was attractive with Nando....I do real love Nando!" Then she said, "Sulu wanted me in romantic situation as lovers but unfortunately he was not lucky because I have already sacrificed my whole love to Nando" 

The query is, who gave Nando a sexually transmitted disease?
