Are Zainab And Barbs Lesbians?

Ex BBA 2012 housemates, Zainab Sheriff from Sierra Leone and Babalwa Mneno aka Barbs from South Africa became very close friends right after the Big Brother show.
They’ve been spotted round town together and in weird positions too.
Every time these two sexy ladies meet up, their lips are all over each other, so I’m going to ask the question everyone is scared to ask: – Are they lesbians?
