The rumour mill is going in to overdrive about him rejoining the band. As much as Robbie was always my favourite I don't really want him to rejoin them. I understand there were a lot of issues when the boys got back together and he's never been very good at dealing with stuff but I do feel it's far too late for him now. It's nice that they're all friends again but they should stay that way.
However, I'm sure if he did come back I would probably get over it pretty quickly! ?
