Are Girls Aloud about to split?

It's increasingly looking like Girls Aloud have reached Splitsville with Nadine saying that she has left the group. None of the others seem to be in a rush to get back together so Cheryl can fully concentrate on her solo career once she has escaped the clutches of X-facor. Talking of X-factor the show is starting to look like a marriage that is on it's last legs. Louis and Simon can't agree on anything and when the two do fall out over an act Cheryl seems to side with Simon rather than Louis. Whilst the guest judges have helped to break up the tension a little as soon as the guest judge goes and leaves Simon, Louis and Cheryl alone together they start to squabble again.
