The new housemates, Miracle Op, Sandra, Theo Traw, and Blue Aiva, were introduced during the Thursday night pool party.
Recall that 20 housemates consisting of 10 Nigerians and 10 South Africans were introduced to the show on Sunday.
The 20 housemates on Monday nominated each other for possible eviction on Sunday.
It is, however, not certain if any housemates will be evicted on Sunday.
There are now 24 housemates battling for the $100,000 grand prize.
