It looks like Gemma Merna is going in.

She could be quite good.

Gemma Collins (TOWIE) and Vicki Pattison (Geordie Shore) have both quit their shows - does this mean they are heading for Australia?

Not confirmed by anyone but the mirror. I don't doubt it is likely but to say it is confirmed is pushing it a little.
