The busty glamour model has claimed that she would be devastated to suffer the humiliation of being the show's first casualty, but it seems her constant moaning and bad behaviour has done her no favours inside the house.
In her short time on 'Celebrity Big Brother', Marsh has argued with Barrymore over her career choices and with 80s popstar Pete Burns, who has also been nominated, about his fur coat, as well as telling viewers about her sufferings throughout her life.
She has also managed to offend publicity-hungry MP George Galloway with her sex talk.
Respect MP Galloway is also up for eviction with bookmakers offering 2/1 and Burns 8/1 to be the first to leave the house.
Clean-cut Ordinary Boys singer Preston has toppled Barrymore as the new 2/1 favourite to with the show.
David Williams of Ladbrokes said: "He's charmed Jodie and Chantelle and now he's charming the punters. Preston's looking good in the house and in the betting."
