All the girls in the Big Brother house have been nominated for eviction this week.
Nush, Steph and Tania will face the public vote on Friday.
The news is in stark contrast to last week, when all the nominees were male.
Bookmakers immediately installed Tania as the odds-on favourite for eviction.
The wannabe It girl has spent her time inside the house either crying or re-applying her make-up.
Tania is 1-3 favourite to be evicted, followed by Steph at 3-1 and Nush at 8-1.
Ladbrokes spokesman Warren Lush said: “We have always believed that if Tania gets put up for eviction she will go.
“She is the hottest favourite for the boot in this series of Big Brother. She had better get her blusher ready for the walk on Friday and the celebrity parties next week.”
Londoner Tania, 22, who lists Peter Andre and Dane Bowers among her conquests, had her latest sobbing fit last night.
She fled the room in tears and threatened to quit the show after Gae jokingly called her “Piggy” on account of her big appetite.
“After Gaetano said she ate like a pig, Tania threatened to walk – she may as well just wait until Friday.
“The bookies see it as a straight fight between a footballer’s ex-girlfriend and a footballer’s ex-wife,” said the spokesman.
Tania had a fling with West Ham reserve player Youssef Sofiane, while Steph, 28, is divorcing her husband, Grimsby Town’s Stacy Coldicott.
