I get what you're saying but even in 2010 they weren't seen as best friends or anything. It had become obvious that Nadine wasn't part of their inner circle and something as trivial such as being the only Girls Aloud member not turning up to watch Cheryl perform FFTL or Promise This already had started that. It didn't work at all. I remember the fuss this caused with the title 'What Will The Neighbours Say'? It was naughty of the GA PR to tweet with that caption!
