Gina is facing off against Sallie Axl in the first eviction after the pair were nominated by the public at the weekend.
They were originally facing eviction alongside Dexter Koh, but he was saved having received the fewest votes by Wednesday night's voting freeze.
It's left the two girls battling it out for survival, and bookies reckon that this could be one of the closest outcomes in the show's history.
“Earlier this week, it looked an absolute certainty that Gina was going to go, but now, it would hardly be surprising if we went into the eviction show on Friday night with Sallie as favourite for the chop,” said William Hill spokesman Joe Crilly.
Meanwhile, TellyMix readers too reckon it'll go the other way, but it's Sallie currently having a narrow lead in our eviction poll.
The model is being backed by 54% of you lot to leave in tonight's first live eviction show.
