Silicone enhanced Orlaith, who claims to be one of Belfast's top models, received four nominations yesterday while rapper Science received five, but is considered rank outsider to go on Friday with odds of 9/4.
The outspoken 22-year old is also second favorite to win the show with odds of 3/1, making it even more likely to be curtains for Orlaith.
Ladbrokes spokesman Warren Lush said: "Even flashing the flesh lots in the next few days is unlikely to save Orlaith. Science saw off Maxwell and is amongst the favourites to win so it looks like an uphill battle for the Belfast beauty."
Meanwhile Geordie dancer Anthony's odds on winning the £100,000 prize money has been cut to evens from 2/1 -- making him one of the most popular housemates to win in 'Big Brother' history.
Science is next up with 3/1, Tory speechwriter Derek, once a rank outsider on 33/1 is third favourite on 7/1. Nerdy engineer Eugene is fourth favourite to win, at 8/1.
Makosi and Kemal, the pair dubbed 'Team Diva' who were once favourites to win, have seen their fortunes reverse with odds of 10/1 and 12/2 respectively.
