Nadine did nothing wrong, just tried to ensure that she wouldn't get the blame again for the split. That's if this is true anyway, there's always been negative stories about them, all the way back to 2002. It could just be the press trying to stir things as usual.
Another article about this says that they have had crisis talks, why would they do that if they've split up?!
The tweet is real .. I've read it.. But I'm not sure if the rest of the media stories ( other girls tweets etc) are.. I don't blame Nadine for making it clear she isn't to blame ..she is protecting herself I think
