Viewers of Big Brother Naija Season 10 were left stunned on Monday morning after housemates Dede and Joanna were asked to leave through an unexpected red phone twist.

The twist unfolded when the red telephone rang inside the house and Dede answered.

The show host, Ebuka instructed her to pick a fellow housemate without explanation, then she chose Joanna, and moments later both were told they had been evicted.

Biggie later did the usual countdown for them to leave the house.

The sudden announcement left housemates in disbelief, with Sultana visibly unsettled while Isabella insisted it might be a fake eviction, recalling similar moments in previous seasons.

This has also fuelled speculation that the duo may have been moved to a secret room, a tactic Big Brother has deployed in past editions to build suspense.

The development comes barely 24 hours after Big Soso, Ivatar, and Doris were evicted during Sunday's live show.
