Lisa, Cameron and Steph have been nominated for eviction from the Big Brother house this week.
They were all chosen by Ray, who was given the responsibility after being named head of the house. None of the other housemates was allowed to nominate.
Ray, who was in tears yesterday when the pressure of his new role became too much, had already revealed that Lisa would be top of his nominations list.
And the Welsh blonde, branded a psycho by the other housemates, is the hottest-ever favourite to get the boot.
Bookmakers Ladbrokes gave her eviction odds of 1/8, followed by Steph at 5/1 and Cameron at 14/1.
Spokesman Warren Lush said: “Tania was only 1/4 at this stage before her eviction. Bookies are wondering whether this eviction is really a contest.”
