Mercy and Ike will rule as joint head-of-house this week.
This is the first time ever that two housemates will rule as head of house at the same time in the Big Brother Naija reality show .
Big Brother offered both housemates the offer, with both of them winning the game of throwing balls into the cup. He however, told them to decide who will be on immunity this week.
The decision saw Ike receiving the immunity.
Both housemates also won 250 Bet Naija coins, for winning this feat
Recall that Esther and Sir Dee got evicted from the Big Brother house last Sunday.
