Lee got a bollocking and still managed to survive the interviews round, however, Stuart is probably far more 'for the entertainment' than Lee ever was.
Jamie's just not really done enough to warrant making it through...
Chris, Stella and Joanna are still in it and my money's on Stella and Joanna atm, but I wouldn't be surprised if they want 1 girl and 1 guy in the final two, so possibly Stella and Chris?
