In the first results show Alexandra sang first, and then that weeks celebrity mentor, and big guests - Robbie Willaims performed. But it was Alexanda that went in at No 1 in the charts, while Robbie had to settle for number 2.

Last week - Cheryl performed first, then Whitney came out and sang. Again, she was last weeks very special guests and it the whole weekend was basically built around her with "Diva Week". But, Cheryl went to No 1. Whitney is in at No 5.

And after tonight - Westlife have shot up the iTunes chart and are now at No 4 on iTunes chart, while Bublé's "Cry Me A River" is at No 102.

Why is it that the secondary guests, those who perform first, are out doing and out selling the big names - the celebrity mentors? Interesting - non?
