Despite Gina and Dexter striking up a close friendship in the house, her boyfriend hopes she stays away.
Gina's partner Edwin Newton claimed that Dexter was a "snake" and could hurt Gina and her chances of winning the show.
He said: "I'm worried because Dexter is a snake, the biggest snake. He knows she's a strong housemate, so he's trying to manipulate the rest of the house against her. And then for him to go and nominate Gina - I knew that was going to happen. "
Speaking to new! magazine this week, Edwin continued: "He's playing a game. She will play along with it because she has to live with him.
"She's not stupid. He would do anything, or double-cross anyone. He says he's jut playing a game but this is how he is in real life - two faced. I even heard he paid girl to pretend to be his girlfriend."
Gina remains the favourite to win the series in next month's final, with bookies having now installed her as the odds-on tip to scoop the £100,000 prize money.
