Dennis has been removed from the Big Brother house following last night's argument.
The argument, which began when Rex put water on Jennifer's painting of Stuart, escalated and Dennis spat in Mohamed's face.
A Channel 4 spokeswoman said: "Spitting in someone's face is seriously offensive and Mohamed was understandably upset. Big Brother has very clear rules about offensive behaviour. Like all housemates Dennis was clearly informed before entering the house that he faced eviction if he acted in an unacceptable manner."
Tonight's eviction, in which Mohamed and Sylvia face the public vote, will still take place.
