Big Brother Naija housemates and couple, Ike and Mercy have made history by becoming the first-ever joint head of house in the reality show. 

During the HOH competition, the pair won the game of throwing balls into the cup and had to be made the joint head of house for the week.

When Biggie told them to decide who will get the HOH immunity this week, Mercy agreed to let her boo Ike have it.

Both housemates also won 250 Bet Naija coins for winning HOH competition.
