i think there could be a catogory of wild cards, i think it would make the most sense, and they have to pad teh 2.5 hour long show out with something and people are tuning in to watch a singing comp, so there has got to be more than the 12 that have already got htrough.
also sharon has said that the feud with danni has been put behind them so she can work on the xfactor, but why would she say that if all she was doing was judges houses with louie? but then again cheryl has been quoted saying that nicole is a threat to her, again why would she be a threat as they havent actually worked together, cheryl is the one with the contract and not even simon can take that away from her untill next year.
