That's not the whole story, from Wikipedia:
In 2009 the Daily Mirror claimed a so called "insider" said "They’re exhausted. They haven’t had a break since they first formed and it has started getting to them. When they started out they were all good friends, but they just don’t seem to get on any more. They are sick of the sight of each other. Brandon tries to be a peacemaker but when he loses it the whole band falls apart. They know taking a break could damage their career but they can’t see a way out and they don’t want to split.”
