Cheryl and Nadine: one has a voice, one has a break...Why people seem surprised that Cheryl Cole won't be singing live on this weekend's X-Factor surprises me. Everyone knows that 90% of the singing done by Girls Aloud is done by Nadine Coyle. Cheryl's job is just to look cute, which she does admirably. The problem with Cheryl, who is evolving into the sort of everymans' national treasure that we haven't seen since Denise van Outen (both men and women like her), is that she is starting to believe her own publicity and think that she really is a singer. 
Cheryl demonstrates why she is such an effective member of Girls Aloud...
Agent Triple P would have only two words of advice: Victoria Beckham. Stick to being a clothes horse and leave the singing to singers...
