With regard to poor old Lauren, a lot of commentators on the analysis sites have pointed out that both of her semi-final songs were originally sung by boy bands and were in the wrong key for her - and as such were actually probably meant for Stereo Kicks. The theory goes that they were expecting Stereo Kicks to go through but couldn't justify it after their terrible sing off (or possibly due to the pictures of one of them on ketamine coming out in the press that week), but they didn't want to invest anything in Lauren going to the final so she was made to sing their songs. That and the bad slots sealed her fate. I felt very sorry for her, and she seemed resigned to it and not at all surprised to leave. I really hope she has success.
With regard to Andrea, I am fuming at Simon's comments on Xtra Factor "Good luck trying to get an Italian to win British X Factor..... There are British contestants who deserve British votes". Not only did he say "we welcome all nationalities here" to Andrea in the auditions, but he also makes an absolute fortune selling X Factor UK around the world, plus the X Factor franchise has been bought in many international countries too. I wonder whether people in all those countries would be so keen to watch if they had heard his comments...
I really think that every attempt has been made to derail Andrea - comments about his weight, his face, lies in the press - yet he has managed to get through to the final simply because he is a lovely guy who can really sing.

Good for him. Let's all enjoy Saturday for his last performance and then wait until he gets to release his own stuff away from the stress of X Factor. I personally will not be watching on Sunday, or next year!
