Sissy is the bookies' favourite to be evicted from the Big Brother house this week.
The Scouser was nominated for the first time, along with Federico and Jon.
But the boys have escaped eviction before, and bookmaker Ladbrokes think Sissy will be the one to go.
Spokesman Warren Lush said: "Punters believe the bell tolls for Sissy. Federico was always going to be nominated but looks to have got over his task failures and has been well backed to win in the last 24 hours.
"Sissy's arguments in recent days have made her less popular while Jon is in the unfamiliar position of being an outsider for eviction."
