There was chaos in the Big Brother Naija Season 11 house last night after finalist Keivo physically ass@ulted fellow housemate Tram over a shirt.

The argument began after Tram called Keivo aside to accused him of wearing a shirt which he claimed belonged to him.

Tram insisted that the shirt Keivo was wearing was his, claiming that even the tag was identical to his.

According to Tram, he came into the house with five identical shirts and  had been looking for one.

Although Tram said Keivo could keep the shirt, he expressed disappointment, arguing that Keivo should have asked him for it if he wanted it.

Keivo, however, maintained that the shirt was his, leading to a heated exchange between the two finalists.

The argument soon escalated into Keivo hitting Tram, forcing other housemates to rush in and separate them.

Big Brother eventually intervened, instructing the housemates to freeze.

Physically hitting someone is highly prohibited in the house. Many expect Big Brother to wield the big stick against Keivo today.
